The short-lived 'Old Academy' of Antiochus of Ascalon is a movement, which arose after Sulla's siege of Athens in 86 BC and the subsequent closure of the Athenian philosophical schools. A product of the lack of institutional unity and the decentralisation of philosophical activity during the First century BC, it is a sign of the contested nature of the Academic identity during this era. After examining Antiochus' construction of a unitary Academy, I will trace the roots of his stance in the Hellenistic Peripatetic tradition. (Georgia Tsouni, University of Bern)
