This comprehensive study offers a critical, comparative analysis of the sources available on Bardaisan and a reinterpretation of his thought. In this connection, special attention is paid to many parallels with Origen, to the possible relationship between Origen, Bardaisan, and their schools, and to the implications of the valuable fragments preserved by Porphyry.
