Pompey Pillar
An approximately 25m red Aswan granite column with a
circumference of 9m, was constructed in honor of the Emperor Diocletain.
Originally from the temple of the Serapis, it was once a magnificent structure
rivaling the Soma and the Caesareum. Nearby are subterranean galleries where
sacred Apis bulls were buried, and three sphinxes.
After his defeat by Julius Caesar
in the civil war, Pompey fled to Egypt where he was murdered in 48 BC;
mediaeval travelers later believed he must be buried here, and that the capital atop the corner served as a container for his head. In fact, the pillar
was raised in honor of Diocletain at the very end of the 4th century. Diocletain captured Alexandria after it had been under siege. The Arabs called it "Amoud
el-Sawari", Column of the Horsemen. The Pillar is the tallest ancient
monument in Alexandria.
