Philo of Alexandria and Early Judaism in Biblical Research: Te Contributions of Ralph Marcus, Earle Hilgert, and Tomas H. Tobin, SJ Michael B. Cover, Marquete University Abstract: Te purpose of this celebratory essay is to trace ways Biblical Research has helped foster early Jewish studies (espe- cially on texts of Second Temple Judaism outside of the Hebrew Bible), both as an independent feld and as an integral part of “biblical research,” with a special focus on Philo of Alexandria. In the essays of Ralph Marcus, Earle Hilgert, and Tomas H. Tobin, SJ, Biblical Research has published the work of scholars who represent three major phases of Philonic studies in the twentieth century: (1) Philo in the era of Wolfson, the Loeb Classical Library translations, and the discovery of the Dead Sea Scrolls (Marcus); (2) Philo in the era of Studia Philonica and the fourishing of source criticism (Hilgert); and (3) Philo in the era of Te Studia Philonica Annual and the composition of exegetical commentaries on individual treatises (Tobin).
