Basilides (or Basileides, Greek: Βασιλείδης; c. 250 – c. 175 BC[1]) was an Epicurean philosopher, who succeeded Dionysius of Lamptrai as the head of the Epicurean school at Athens. c. 205 CE.[2][3] It is not certain who succeeded Basilides: Apollodorus is the next Epicurean leader we can be certain about, but there may have been at least one intermediate leader, and the name Thespis has been suggested.[4] Barnes and Brunschwig suggested that Basilides of Tyre and Basilides the Epicurean could be the same Basilides.[5]
