This set of essays originate in Lagarde"s printed collection Orientalia. The first contribution to this booklet is Lagarde"s analysis of the Coptic manuscripts of the Göttingen library. In addition to describing the manuscripts, he provides data concerning the content, including the biblical passages slated for various liturgical seasons, in keeping with the character of the material. To this is attached an article on selections of the Coptic translation of the Old Testament. Here annotated extracts of the Bible are presented in their original Coptic script, along with relevant apparatus by the author.
