Abstract : In preparing the critical edition of Cyril’s Against Julian, substantial new evidence regarding the indirect tradition of Cyril’s massive refutation of Julian’s pamphlet Against the Galileans has come to light, including some new fragments of both Julian’s and Cyril’s work and a great number of quotations from Cyril’s Against Julian by the Byzantine historian and exegete Michael Glycas (12th century). A thorough investigation of the manuscript transmission has, moreover, shown that the late Augsburg Humanist David Hoeschel (1556-1617) intended to produce a Greek edition of Cyril's Against Julian and for that purpose was comparing the readings of various manuscripts between the years 1613-1617. The Paris manuscript Q (Parisinus supplementi graeci 424: saec. XVII ineuntis) may actually have been written in Augsburg with Hoeschel’s planned edition specifically in mind. The article concludes with an addendum on the newly found Codex Patmos 263 by Katarzyna Prochenko and Christoph Riedweg.
