The Alexander Mosaic from the House of the Faun (c. 100 BCE) is a Republican Roman floor mosaic made of tiny tesserae, depicting Alexander the Great charging Darius III at the Battle of Issus. It is a required Unit 2 work and a copy of a lost Greek painting, showing Rome's love of Greek art.
The Alexander Mosaic is a huge floor mosaic from the House of the Faun, one of the largest private homes in Pompeii, dated around 100 BCE during the Roman Republic. It is built from tesserae, which are tiny cut cubes of stone and glass. Millions of them. The scene shows Alexander the Great on horseback, bareheaded and fearless, crashing into the army of the Persian king Darius III, who turns back in panic from his chariot. Most scholars read it as the Battle of Issus.
Here is the part the AP exam cares about most. This Roman mosaic is almost certainly a copy of a lost Hellenistic Greek painting from around 310 BCE. So you are looking at a Roman translation of Greek art, installed in a rich Roman's floor to show off his taste, wealth, and education. The dramatic diagonals, the foreshortened horse seen from behind, the crowded tangle of spears, and the emotional faces all carry Hellenistic drama into a Roman domestic space.
This is one of the required works in Topic 2.5, Unit 2 (Ancient Mediterranean, 3500 BCE-300 CE), so you can be asked to identify it fully by title, date, culture, and materials. It does double duty in the course. First, it shows what Republican Roman patrons valued, which was Greek art and the status that came with owning it. Second, it preserves Hellenistic style, with theatrical movement, illusionistic depth, and raw emotion, even though the original painting is gone. That makes it a go-to example for contextual analysis questions about patronage, function (decorating a private home), and cultural borrowing across the Mediterranean.

Great Altar of Zeus and Athena at Pergamon (Unit 2)
Both are dramatic Hellenistic-style battle scenes, and the 2018 LEQ literally asked you to pair the Pergamon battle frieze with another battle work. The mosaic shows a historical battle while the altar shows a mythological one, which is exactly the kind of contrast a comparison essay rewards.
Doryphoros (Spear Bearer) (Unit 2)
Same survival story. The Doryphoros we study is a Roman copy of a lost Greek bronze, and the Alexander Mosaic is a Roman copy of a lost Greek painting. Together they prove how much of Greek art we only know through Roman admiration.
Gigantomachy (Unit 2)
The gigantomachy on the Pergamon altar uses a cosmic gods-versus-giants battle to glorify a ruler's victories. The Alexander Mosaic does similar glorification work but with a real, named conqueror instead of myth.
Head of a Roman Patrician (Unit 2)
Both are Republican Roman works from roughly the same era, but they pull in opposite directions. The patrician portrait is hyper-Roman veristic realism, while the mosaic is Rome borrowing Greek idealized drama. Knowing both lets you talk about Republican art as a mix, not one style.
Expect this work in identification-based MCQs (culture, date, material, original context) and as strong FRQ evidence. The 2018 LEQ showed the Pergamon altar battle scene and asked for another work depicting a battle, and the Alexander Mosaic is a textbook choice for that comparison. To use it well, you need to do more than name it. Be ready to explain its function as floor decoration in a wealthy Pompeiian house, its status as a copy of a Hellenistic Greek painting, and specific visual evidence like Alexander's bareheaded charge, Darius's panicked retreat, the foreshortened horse, and the forest of spears. Full identification means all four identifiers, so memorize: c. 100 BCE, Republican Roman, mosaic (tesserae), House of the Faun in Pompeii.
Both are violent, dynamic battle scenes in the Hellenistic style, so they blur together fast. Keep them apart by subject and medium. The Pergamon altar is a Hellenistic Greek marble relief showing a mythological gigantomachy, gods fighting giants. The Alexander Mosaic is a Republican Roman floor mosaic showing a historical battle between named humans, Alexander and Darius. Myth in stone versus history in tesserae.
The Alexander Mosaic is a Republican Roman floor mosaic from c. 100 BCE, found in the House of the Faun in Pompeii, and made of tiny stone and glass tesserae.
It depicts Alexander the Great charging the Persian king Darius III, most likely at the Battle of Issus, with Darius fleeing in his chariot.
It is widely believed to copy a lost Hellenistic Greek painting, which makes it key evidence for both Greek painting techniques and Roman taste for Greek art.
Its function was domestic display, since a wealthy Roman put it on his floor to broadcast education, wealth, and cultural sophistication.
On the exam it pairs naturally with other battle imagery like the Pergamon altar frieze, with the historical-versus-mythological contrast doing the heavy lifting in a comparison essay.
It's a large Republican Roman floor mosaic, c. 100 BCE, made of tesserae and found in the House of the Faun in Pompeii. It shows Alexander the Great attacking the Persian king Darius III in battle, and it's a required Unit 2 work for AP Art History.
It's Roman. The mosaic itself was made around 100 BCE in Republican Rome, but it copies a lost Hellenistic Greek painting from around 310 BCE. On an ID question, the culture is Republican Roman, and the Greek connection is your contextual analysis point.
Most scholars identify it as the Battle of Issus (333 BCE), where Alexander the Great defeated Darius III of Persia. Alexander charges in from the left while Darius wheels his chariot around in retreat.
The Pergamon altar is a Hellenistic Greek marble relief showing a mythological battle of gods and giants, while the Alexander Mosaic is a Roman tessera mosaic showing a real historical battle between Alexander and Darius. Both share dramatic Hellenistic style, which is why exams pair them.
It decorated a room in the House of the Faun, one of the grandest private homes in Pompeii. Displaying a copy of a famous Greek painting in your floor advertised the owner's wealth, taste, and knowledge of Greek culture, which is the patronage angle the AP exam loves.
