Small Greek city near Tanagra, on a rocky peninsula between two bays. Its most famous monument is the temple of Artemis and its neighbouring buildings. The best harbour in northern Boeotia, Aulis is most famous as the point of assembly for the Achaean expedition against Troy. Here Iphigenia was sent to be sacrificed for a safe voyage of the fleet, a theme developed by Euripides. Hesiod (Op. 651 ff.) sailed thence to Euboea. Strabo (9. 2. 3) states that an Aeolian fleet sailed from it to Asia. Agesilaus attempted to sacrifice there in 396 bce, before his expedition to Asia (Xen. Hell. 3. 4. 4), but the Boeotians interrupted the ceremony. It was the principal base for Epaminondas' unsuccessful naval ambitions in 364 bce. In 312 bce Antigonus (1)'s admiral Ptolemaeus docked 150 ships there in the conflict with Cassander (Diod. Sic. 19. 77. 4). L. Aemilius Paullus (2) visited Aulis in 167 bce to view the anchorage of the Achaean fleet.
