The Pergamon Altar

The Pergamon Altar, c. 200-150 B.C.E., 35.64 x 33.4 meters, Hellenistic Period (Pergamon Museum, Berlin); speakers: Dr. Beth Harris and Dr. Steven Zucker

[0:00] [music]

Dr. Steven Zucker: [0:04] I love Greek sculpture. I love the Archaic. I love the Classical, and all of its restraint and harmony, but I have to tell you, I really love the Hellenistic. The reason I do is because of two fragments from a great frieze from Pergamon. One has Athena at its center and one has Zeus.

Dr. Beth Harris: [0:22] I can see why you love these sculptures. They combine what’s most wonderful about ancient Greek sculpture in the love of the body, but also the sense of expressiveness and drama which we associate so much with the Hellenistic.

Dr. Zucker: [0:38] The Hellenistic refers to the last period of Greek art, the last phase of Greek art after the death of Alexander the Great. Now Alexander, whose father had been a king in northern Greece, in Macedonia, had been able to conquer all of Greece, and ultimately conquer an enormous territory, well beyond Greece’s original borders.

Dr. Harris: [0:56] In so doing, he expanded the influence of Greek culture across a much wider area.

Dr. Zucker: [1:04] That’s right. He, in a sense, Hellenized this area, or made it Greek. His expanded territory reached from the ancient civilization of Egypt all the way to the border between Persia and India, to the Indus Valley itself. It was an enormous territory. But after he died, his empire was divided among his four generals.

[1:24] One of those generals saw a hilltop near the coast of Turkey, which he believed was an important defensive position, and there founded the garrison of Pergamon that became, ultimately, the kingdom of Pergamon.

Dr. Harris: [1:35] Those are the people that built this fabulous altar and sculpted this fabulous frieze. What’s going on here is a battle between the giants and the gods and goddesses of Mount Olympus. We’re witnessing a celestial battle of enormous proportions.

Dr. Zucker: [1:53] This is the great mythic battle where the giants battle the Olympian gods for supremacy of the earth and the universe. Let’s take a close look at it. Let’s start with the fragment that has Athena at its center. She is graceful and beautiful even as she battles a ferocious giant, a Titan.

Dr. Harris: [2:11] It’s clear who’s going to win. Athena looks totally in control. She’s grabbed Alcyoneus by the hair, pulling him out of the earth, disempowering him. His mother on the other side [is] completely unable to help him, although she’s wild with fear over what’s about to happen to her son.

Dr. Zucker: [2:29] Look at the way the artist, whoever it is, has actually constructed this image. My eye starts with Athena herself, where her head would have been. My eye rides down that beautiful arm until it’s grasped almost tenderly by Alcyoneus. It continues around his elbow and then across his face and down his chest. I notice that one of Athena’s snakes is biting him on his right side.

[2:54] My eye then sweeps down that gorgeous curve that is his body, his torso, that leads into his leg. But it’s slowed down by almost the staccato of the intersections of the deeply carved drape that belongs to Athena. Of course, that all leads us right back to Alcyoneus’s mother.

Dr. Harris: [3:13] It’s as though Athena, this powerful, in-control goddess, is bracketed on either side by these passionate, wild figures who are being defeated. And at the same time, Athena is being crowned by a winged Nike, who comes from behind with a crown for her head.

[3:33] There’s really a sense here of figures coming from behind, of figures coming from below, of something that’s completely in flux. Something that’s completely in motion, with an incredible sense of drama.

Dr. Zucker: [3:45] It’s as if the entire surface of this marble is swirling in a counterclockwise motion around Athena’s shield, which is at its very center. It is full of diagonals, which activates the surface. It is full of the deepest carving that creates this brilliant contrast between the highlights of the exposed bodies and the dark shadows behind them.

Dr. Harris: [4:07] What’s also amazing to me is the complexity of the positions of their bodies. Athena, who moves toward the left, keeps her arm to the right. Then Alcyoneus lifts his head up, twists his shoulders. His legs spill back behind him. We’re really talking about virtuoso sculpting here of the human body.

Dr. Zucker: [4:30] Imagine what this would have looked like when it was painted. We think so often about Greek sculpture as being just this brilliant white marble. We have to remember that all of this was brilliantly painted. Let’s take a look at the fragment with Zeus at its center.

Dr. Harris: [4:44] Like Athena, he seems composed and totally in control. Even as he rushes forward, we have no doubt that he’s the victor here.

Dr. Zucker: [4:53] Zeus is an enormously powerful figure. We have this beautiful exposed chest and abdomen and this wild, almost living, drapery that seems to whip around his legs. He is taking on not one but three giants at the same moment.

Dr. Harris: [5:08] Luckily, he’s the king of the gods. He’s got things like eagles and thunderbolts to help him out.

Dr. Zucker: [5:14] That’s right. If you look at the upper right, you can see that an eagle, Zeus’s emblem, is taking on the elder Titan. As the eagle is preoccupying that giant, Zeus is able to turn his attention to the giant at his feet, who is on his knees and is shortly going to be vanquished.

[5:31] You can see that on Zeus’s other side, he’s just finished putting away a giant who almost seems to be sitting on a rock. He’s got stuck in his thigh what looks like a torch, but is actually the way that the Greeks represented Zeus’s thunderbolts.

Dr. Harris: [5:46] Ouch, that has to hurt.

Dr. Zucker: [5:47] It does. There is a sense of heroism, a sense of balance, even as there is a sense of the momentary and a kind of excitement that really pulls us in. The story of the gods and the giants is a story that was really important to the Greeks. It was really a set of symbols that spoke of the Greeks’ fear, but also optimism that they could overcome chaos.

Dr. Harris: [6:10] This battle is really a metaphor for the victory of Greek culture over the unknown, over the chaotic forces of nature.

Dr. Zucker: [6:20] Right, and also represents the military victories over cultures that they didn’t understand and that they feared.

[6:27] Let’s walk up the stairs of the great altar into the most sacred part of the altar, where the fire, presumably to Zeus, would have been lit, and where sacrifices might have been offered.

[6:36] You had mentioned earlier that the figures seem to almost spill out away from the wall, and I think that’s most clearly seen as we walk up the stairs. There are moments when the figures that are carved in this high relief actually rest their knee on the stairs, literally enter our space.

[6:53] For instance, one of the sea nymphs, whose legs actually end in the tail of a great serpent, coils her tail on one of the stairs. There is this wonderful way in which they literally pour out into our world.

Dr. Harris: [7:06] And so this whole drama is unfolding around us, moving into our space, and it must have been an amazing thing to have seen.

Dr. Zucker: [7:16] One of the questions that comes to mind is, why are these sculptures here in Berlin? The answer can be found in the political ambitions of Prussia at the time. They very much wanted to be the equal of the French and the British.

[7:28] That meant, in part, to have great museums that expressed the civilizations of the past, so they could be in a sense the inheritors of the great classical tradition, which was so revered in the 19th century. Berlin in some ways wanted to be the new Rome.

Dr. Harris: [7:43] One of the great things about being in the Pergamon Museum in Berlin is that, instead of just putting what remains of the frieze on the wall, they’ve reconstructed the altar and as much of the frieze as possible, and so we really get a sense of what this was like in the city of Pergamon in the 3rd century B.C.

Dr. Zucker: [8:05] Right. And so if this was the 3rd century, we would be on the acropolis, this hilltop, in the city of Pergamon, about 20 miles from the coast in what is now Turkey. We would walk up this hill and we would find the altar of Zeus, surrounded by a great library that is reported to have had 200,000 scrolls, a garrison for soldiers, a royal palace for the king.

Dr. Harris: [8:28] And so this whole drama is unfolding around us, moving into our space, and it must have been an amazing thing to have seen in the 2nd century B.C.

But Ge [goddess of earth] . . . brought forth the giants, whom she had by Uranus [god of the sky]. These were matchless in the bulk of their bodies and invincible in their might; terrible of aspect did they appear, with long locks drooping from their head and chin, and with the scales of dragons for feet.—Apollodorus, Library 1.6.1

The battle between the gods and giants

The ancient Greeks represented the mythological battle between the Olympian gods and the giants in a wide variety of media—from miniature engraved gemstones and vase paintings, to over-life-sized architectural sculptures.

Perhaps the most famous and well-preserved of these decorates the Pergamon Altar. The Altar once stood in a sacred precinct on the acropolis of the ancient city of Pergamon (on the west coast of modern-day Turkey), which was ruled by the Attalid dynasty from 282–133 B.C.E.

In comparison to other Hellenistic kingdoms (kingdoms formed after the death of Alexander the Great in 323 B.C.E. and stretching from the eastern Mediterranean to Central Asia), Pergamon emerged relatively late on the scene. Monumental building projects—including the Altar—served as an important way for the Attalids to stake their claim as legitimate inheritors of Alexander’s empire and, by extension, the legacy of Classical Greece.  

In the early 20th century the Altar found a new home in Berlin, Germany—2,677 kilometers from its original location—where it has remained on view since 1930 as the centerpiece of the museum bearing its name (see end note below and learn more here about how the altar ended up in Berlin). [1]

The Altar’s architectural framework alone is impressive—it comprises a monumental Π-shaped structure surrounded by columns and accessed by a grand staircase. However, its most eye-catching feature is undoubtedly the frieze, a massive 113 meters long and 2.3 meters high marble high-relief that wraps around the building’s entire exterior and depicts the mythological battle between the Gods of Mount Olympus and Giants.

The battle, known as the gigantomachy—from the ancient Greek γίγαντες (“giants”) and μάχη (“battle”)—represented a crucial shift for the ancient Greeks: the old religion, which was rooted in the natural world (for example, Ge, the earth goddess and mother of the giants), was overthrown by the new, civilized order of the Olympian gods (for example, Zeus, Athena, and others). According to the myth, the gods received a prophecy that the giants could only be defeated with the help of a mortal. Zeus (assisted by Athena), called upon the hero Herakles who dealt the decisive blow by shooting them with arrows. [2] Over time, the visual tradition of the gigantomachy expanded to include the presence of other Greek heroes, who also aided the gods.

Viewing the Altar

The approach

Ancient viewers would have first approached the Altar from its rear, where the gigantomachy’s main protagonists—the god Zeus and goddess Athena assisted by the hero, Herakles—decisively defeat their giant antagonists. From this view, the figures in the relief appear inaccessible as they tower above—their over-life-sized bodies often twisting into near-impossible positions in the midst of battle. While the stepped platform made it possible to access the frieze up close, this would only have placed viewers in uncomfortable proximity to the immortal skirmish.

The sides of the altar

As visitors continued along either side of the Altar they encountered gods and goddesses thematically assembled (for example, the twin gods Apollo and Artemis with their mother Leto). Despite the Altar’s fragmentary state of preservation, many of the figures can be identified—now, as in ancient times—through inscriptions included above (in the case of the gods) and below (in the case of the giants) the frieze.

The Front of the Altar

Once ancient viewers reached the Altar’s front the characters began to increasingly invade their space, projecting outwards to the point where some giants (such as those battling water divinities on the north side) even kneel on the steps. It’s as if they are inviting us to join the terrifying conflict as we ascend. Despite the immense number of figures on the frieze, each panel manages to offer new discoveries for its viewers.

A battle for Hellenistic times

This version of the gigantomachy is characteristic of the Hellenistic style (Greek art dating from c. 323 to 31 B.C.E.). It is highly dramatic, both in terms of the overtly exaggerated dynamism of the figures’ bodily positions and the pathos exhibited by their expressions. The frieze, and its enigmatic central characters, first draw viewers in via the two central panels featuring the god Zeus and the goddess Athena.

The goddess Athena grasps the giant Alkyoneos by his unruly wavy hair, pulling his face to the left. His right arm grasps in vain at Athena’s forearm. A serpent, the agent of Athena, restrains the giant’s body and simultaneously exposes his anatomy to the viewer. Alkyoneos kneels on his right leg, while his left leg extends outwards, crossing over Athena’s striding form. His face, with its wrinkled brow and open mouth, exaggerates his suffering. It is framed by the interlocked arms of giant and goddess as well as by the giant’s wings, which fill the top of the panel in low relief. Ge, goddess of the earth and mother of giants, emerges from the ground to beg for her son’s life. Notably, the earth goddess is the only figure to be identified with an inscription on the frieze itself (rather than above or below, as with the other gods and giants) emphasizing her role as an intermediary. Nevertheless, Nike, goddess of Victory, has already flown in to crown Athena, sealing Alkyoneos’ fate.

The giants from the Zeus panel are rendered from three distinct perspectives. One, directly to Zeus’ left, kneels on his left leg, his body not nearly as extended as Athena’s opponent. A second, furthest from Zeus, shows us his muscular back, buttocks, and serpentine legs as he turns toward the god with his bearded face in profile. The third, to Zeus’ right, has been pierced by Zeus’ weapon, the thunderbolt, and sits in profile view, wounded on the ground. Although barely preserved, just to the right of this wounded giant the figure of Herakles can be detected by a paw from the Nemean lion’s skin (an attribute of the Greek hero Herakles). Herakles’ essential role in the gigantomachy has been appropriately emphasized through his proximity to Zeus. (In fact, the Attalid’s choice to monumentalize this particular myth was likely tied to the presence of the Greek hero who was the father of Telephos, the mythological founder of Pergamon).

Just as impressive as their dynamic poses, these two panels depict a diversity of giant types—from human to animal. On the Altar, a giant could be fully humanized, and even wear armor. But many more are anguiform (snake-like) and some possess further animalistic features. A few, besides, are even more overtly animal-like, almost monstrous.

Visual traditions of the gigantomachy 

Some of the earliest representations of the gigantomachy, such as the frieze from the Treasury of the Siphnians at Delphi (c. 525 B.C.E.), appear to follow Hesiod’s Theogony, in which he describes the giants as born wearing  “gleaming armor with long spears in their hands.” [3] For example, a detail from the north frieze shows the god Apollo and goddess Artemis advancing towards a fleeing giant, who turns back to look at them. The Archaic-style giants are uniformly depicted in armor (similar to the that worn by hoplites, the foot soldiers of ancient Greece) and face the gods almost as equals.  To the left of this scene, a lion—pulling a goddess’s chariot—attacks a giant. The frieze is dominated by overlapping profiles of gods and giants who stride toward one another but there is little indication of physical engagement between the figures, save for the lion and the giant.

Over time and in countless artworks, artists reimagined the gigantomachy to include a variety of characters, interactions, and attributes, eventually making the Pergamon Altar version possible. One of the most recognized examples of the gigantomachy, on the east metopes of the Parthenon (447–438 B.C.E.), promoted the Athenians as civilizers and preservers of Greek culture over the barbarous Persian forces. Following the Persian wars (545–448 B.C.E.) the attire of the giants changed to include animal skins (difficult to see on the metopes today). The Classical-style Parthenon metopes have evolved from the Archaic depictions of the Siphnian treasury to emphasize a clearer distinction between god and giant. The gods are generally portrayed above the giants; the giants have shed the majority of their hoplite armor in favor of donning animal skins and wielding rocks or clubs, which connect them to the natural world. 

The Athenian Parthenon, and the city of Athens more broadly, became incredibly influential in both the Classical and later periods. Hellenistic rulers, including the Attalid kings of Pergamon, sought to emulate Athens and, significantly, forged visual connections between their own newly formed kingdoms and the established cities of mainland Greece. The Pergamene Acropolis contained numerous sculptural and architectural references to Athens, including an over life-sized marble copy of the colossal chryselephantine (gold and ivory) Athena Parthenos that once stood inside the Parthenon. The Altar too may have contained compositional allusions to the renowned Athenian temple, namely in the striding figures of Athena and Zeus, whose poses resemble that of Athena and Poseidon on its west pediment (see a reconstruction drawing of it here).

On the Parthenon, the Athenians used myths to provide commentaries on their contemporary reality. The barbaric giants, decisively defeated by the Olympian gods and assisted by Greek heroes, served as an appropriate visual metaphor for the Persians, who had desecrated the sacred sites of Greece including the Athenian Acropolis. Similarly, were the figures of giants on the Altar meant to evoke the enemies of Pergamon—the Gauls and the Macedonians?

From myth to reality: the Pergamon Altar as a victory monument

Prior to the construction of the Altar, the first king of Pergamon, Attalos I, set up monuments to commemorate his victory over the Gauls and legitimize his rule. The fact that his sons (Eumenes II and Attalos II) also fought the Gauls has prompted scholars to consider the Great Altar as another victory monument.

Single figures of Gauls from the earlier victory monuments that survive in the form of Roman copies bear clear resemblance to the giants from the Altar frieze. Compare the thick, curly, wild locks of hair of the Wounded Gaul in the Louvre to that of a giant from the Zeus panel. The Gauls were known to have covered their hair with a watered down plaster mixture, giving it a thickened rough appearance. [4] While the giants on the Altar were not exact quotations of the Gauls, their agonized twisting figures likely reminded viewers of the earlier monuments, some of which were probably erected nearby.

Left: Helmeted giant striding forward with shield; right: trampled giant with shield, Pergamon Altar, c. 197–139 B.C.E. (Staatliche Museen, Berlin)

The armored giants in the frieze evoke comparison with another contemporary adversary. Two giants from its east side—one striding toward the goddess Artemis bearing a shield, and a second trampled beneath Hera’s chariot, also holding a shield—bear characteristically Macedonian armor. The shield of the trampled giant is adorned with a starburst, a common emblem of the Macedonians. [5]

The Altar is not alone in alluding to victory of Pergamon over the Macedonians—images of their armor also appear at the Sanctuary of Athena, located just north of the Altar precinct on the Pergamene acropolis. The emphatic inclusion of these attributes may have served as a means to quash rumors that Eumenes II was considering peace or an alliance after the Third Macedonian War (172–168 B.C.E.), in which the Attalids had fought alongside the Romans. Furthermore, it has been suggested that the Altar—similar to other multifunctional structures in cities and sanctuaries throughout the Greek world—also served as a treasury for arms and armor captured in the Gallic and Macedonian wars (among others). These reminders—both real and sculpted—would have strengthened viewers’ visual associations between the enemies of Pergamon and the giants on the Altar frieze.

As ancient visitors traversed from the rear to the front of the Altar they witnessed the metamorphosis of giants from overtly monstrous anguiform and animal-headed representations to fully anthropomorphic figures equipped with the arms and armor of Attalid enemies. [6] Taking its cue from the example of the Classical Parthenon, the Pergamon Altar went one step further in encouraging its viewers to visually compare contemporary adversaries with the fearsome giants. Ultimately, in conflating a mythological battle with contemporary Attalid victories the Altar elevated the triumph of Pergamon to that of the gods.


End note

The Pergamene Acropolis was first rediscovered as early as the 14th century when Cyriacus of Ancona, an Italian antiquarian, visited the ruins. However, the site remained unexcavated until the late 19th century when the German engineer, Carl Humann, was commissioned by the Ottoman Empire to survey the area for a road-building project. Sultan Abdul Hamid II allowed the Germans a permit to fund their own excavations at Pergamon, where archaeologists have continued to work for the past 140 years under the aegis of the German Archaeological Institute and with the permission of the Ministry of Culture and Tourism of the Republic of Turkey (for more information, see the Pergamon Excavation Project). Alexander Conze, director of the Berlin Antikensammlung (Collection of Classical Antiquities), oversaw the legal purchase and transport of the Altar, in its entirety, to Berlin, where it was first displayed in the Altes Museum until the Pergamon Museum was constructed. During World War II, the Altar was moved to a bunker for protection. At the conclusion of the war, the Soviet Union claimed the Altar and transferred it to St. Petersburg. It was eventually returned to Berlin in 1958. In the late 1990s, the Altar was part of a conversation about the repatriation of Turkish heritage. Since the modern Republic of Turkey was officially founded in 1923, the legality of some excavations and purchases conducted under the authority of the Ottoman Empire have been disputed (especially in cases where documentation hasn’t survived). However, unlike some other controversial objects remaining in foreign museums, the Altar’s acquisition has been accepted as legal by the Turkish government.
