Hellenopolis was a city in Anatolia (perhaps Bithynia or Mysia) founded by an Attalus, by gathering together the inhabitants of a number of Greek cities.
as was assembled by the Ptolemies' rival Attalus at the Library of Pergamum, it did have a room devoted to the study of anatomy and an installation for astronomical observations.
Olympias, Alexander's mother, has Philip's last wife Eurydice, her infant daughter and her influential uncle, Attalus, killed.
But Antiochus was at of length entirely defeated, chiefly through the efforts of Attalus, king of Pergamon, who defeated him at the Battle of the Harpasus and drove him out of Anatolia.
