In 2001, the first volume in the then-new commentary series on Philo was published: On the Creation of the Cosmos according to Moses. Introduction, Translation and Commentary, by David T. Runia. Then followed Philo’s Flaccus (by Pieter van der Horst) in 2003; On Virtues in 2011 (by Walter T. Wilson), and On Cultivation (by Albert C. Geljon and David T. Runia), in 2013.
Several volumes have been in the making for several years no, and it seems that in the not so far away future, there will be published several new volumes.
Maybe the volume published most recently introduces a new wave of commentaries on Philo. Anyway, at the very end of 2019, it was announced that a fifth volume was out:
Philo of Alexandria On Planting
Introduction, Translation and Commentary
Philo of Alexandria Commentary Series (PACS)
By Albert C. Geljon and David T. Runia
The volume is introduced thus by the publisher:
The Jewish exegete and philosopher Philo of Alexandria has long
been famous for his complex and spiritually rich allegorical
treatises on the Greek Bible. The present volume presents
first translation and commentary in English on his treatise De
plantatione (On planting), following on the volume devoted to On
cultivation published previously by the same two authors. Philo
gives a virtuoso performance as an allegorist, interpreting Noah’s
planting of a vineyard in Genesis 9.20, first in theological and
cosmological terms, then moving to the spiritual quest of both of
advanced souls and those beginning their journey. The translation
renders Philo’s baroque Greek into readable modern English. The
commentary pays particular attention to the treatise’s structure, its
biblical basis and its exegetical and philosophical contents.
The next volume to be published will be On the Life of Abraham, written by Ellen Birnbaum and John M. Dillon. Scheduled for Apr. 22. 2020.
Congratulations to the writers and editors for keeping this commentary series alive!
