The Series Graeca has been set up with the explicit aim of filling the gaps in the Patrologia Graeca and redoing editions published elsewhere in a deficient way. Priority is given to post-Nicene authors, thus completing the Berlin corpus. The works of Gregory of Nazianzus are published in the subseries Corpus Nazianzenum. The series also includes editions of Greek translations of and Byzantine commentaries on the works of Thomas Aquinas issuing from the Thomas de Aquino Byzantinus project. [Further reading]
