The Studia Philonica Annual celebrated its twenty-fifth anniversary last November, a fitting indication of the flourishing state of Philonic studies and a far cry from the short-lived and less polished Studia Philonica of the 1970s. The annotated (2011) and provisional (2012-2014) bibliographies of works directly or significantly addressing Philo and eight book reviews are preceded by eight articles. The articles reflect a range of interests: philosophical/theological issues, Philo’s patristic Nachleben, and a Special Section on non-biblical Hellenistic Jewish and non-Jewish sources. The conceptual and methodological sophistication of these articles appears throughout.
