The gigantomachy is the mythological battle between the Olympian gods and the Giants, shown on the frieze of the Great Altar of Zeus and Athena at Pergamon (c. 175 BCE), where its swirling, high-relief drama defines the Hellenistic style tested in AP Art History Unit 2.
Gigantomachy literally means "battle of the Giants." In Greek myth, the Giants tried to overthrow the Olympian gods, and the gods (with some mortal help) crushed them. For AP Art History, the term points you straight to one required work, the Great Altar of Zeus and Athena at Pergamon (c. 175 BCE), whose massive sculptural frieze wraps the gigantomachy around the altar's base.
The Pergamon frieze isn't just an illustration of a story. It's the textbook example of the Hellenistic style. Figures twist, lunge, and spill out of the frame; Athena drags a winged Giant by the hair while his mother Gaia begs for mercy. The carving is so deep it's almost sculpture in the round, and some figures literally crawl onto the staircase visitors climb. The subject also worked as propaganda. The kings of Pergamon used gods-defeating-Giants as an allegory for their own victory over the Gauls, framing themselves as civilization triumphing over chaos.
Gigantomachy lives in Topic 2.5 (Unit 2 Required Works), attached to the Great Altar of Zeus and Athena at Pergamon. Knowing the term lets you do three things the exam rewards. First, you can correctly identify the frieze's subject matter, which is part of a complete identification. Second, you can explain how form serves content, since the chaotic, emotional, deeply carved figures match a story about cosmic struggle. Third, you can talk about function and context, because the mythic battle doubles as political messaging about Pergamene power. That subject-style-context triangle is exactly what Unit 2 essays ask you to build.

Great Altar of Zeus and Athena at Pergamon (Unit 2)
This is the required work where gigantomachy appears. The frieze IS the gigantomachy, so any question about the altar's subject, style, or political meaning runs through this term.
Alexander Mosaic from the House of the Faun (Unit 2)
Another required battle scene packed with emotion, movement, and tangled bodies. Pairing it with the Pergamon frieze shows you can compare how different media (mosaic vs. relief sculpture) create the same Hellenistic-flavored drama.
Doryphoros (Spear Bearer) (Unit 2)
The perfect contrast. Doryphoros is Classical calm, balance, and idealized restraint. The gigantomachy frieze is everything the Classical period held back, which makes the pair a ready-made before-and-after for style-change questions.
Grave Stele of Hegeso (Unit 2)
Both are Greek relief sculpture, but Hegeso is quiet, shallow, and domestic while the gigantomachy is loud, deep, and cosmic. Comparing them shows how relief carving can serve totally different emotional goals.
This term has real exam history. The 2018 LEQ Question 1 showed the battle scene from the Great Altar of Zeus and Athena at Pergamon and asked you to identify another work and build a comparison. So the move isn't just defining gigantomachy. You need to recognize the frieze on sight, name its subject, and use it as evidence about Hellenistic style or political meaning. In multiple choice, expect image-based stems asking what the scene depicts, what stylistic period it belongs to, or why a Pergamene king would commission this particular myth. The strongest answers connect the violent subject to the dramatic form to the propaganda function.
Both are mythic wars against the Olympians, but they're different enemies. The Titanomachy was the gods' earlier war against the Titans (Zeus's parents' generation). The gigantomachy came later, against the Giants, children of Gaia. The Pergamon frieze depicts the gigantomachy. If you write "Titans" in an essay about the altar, you've mislabeled the subject.
Gigantomachy is the mythological battle between the Olympian gods and the Giants, not the Titans.
On the AP exam, the term attaches to one required work, the frieze of the Great Altar of Zeus and Athena at Pergamon, c. 175 BCE.
The frieze's twisting bodies, deep carving, and raw emotion make it the defining example of Hellenistic style in Unit 2.
The Pergamene kings used the gigantomachy as political allegory, casting their victory over the Gauls as order defeating chaos.
A 2018 LEQ used the Pergamon battle scene as its stimulus, so be ready to identify the work and compare it to another piece.
It's the mythic battle between the Olympian gods and the Giants, depicted on the sculptural frieze of the Great Altar of Zeus and Athena at Pergamon (c. 175 BCE), a required work in Unit 2.
No. The war against the Titans is the Titanomachy. The gigantomachy is a separate, later war against the Giants, the children of Gaia, and that's what the Pergamon frieze shows.
It was propaganda. The Attalid kings of Pergamon framed their real-world victory over the Gauls as the gods defeating the Giants, presenting Pergamon as civilization triumphing over barbarism.
Doryphoros (c. 450-440 BCE) shows Classical ideals of calm balance and restraint. The gigantomachy frieze (c. 175 BCE) is Hellenistic, full of violent movement, dramatic emotion, and carving so deep figures spill onto the altar's stairs.
Yes. The 2018 LEQ Question 1 used the battle scene from the Great Altar of Zeus and Athena at Pergamon as its stimulus and asked for a fully identified comparison work.
