This online edition presents the Third Letter of Gregory Palamas to Gregory Akindynos – a crucial text for the history of the Hesychast controversy – in the two different versions that have come down to us. Besides the first-time synoptic and searchable edition of the two Greek texts, the website provides information on and links to the manuscripts, English summaries of both versions, information on the historical background, annotations to the texts and a bibliography. 
The digital edition was realised by Renate Burri (synopsis and editing of Greek texts, website design, preparation of DTD/XML documents, English texts) and Rafael Schwemmer / text & bytes (technical implementation, website design).
