An abridged version of the Slavonic Scaliger Patericon is shown to be copied both from Cyrillic and Glagolitic antigraphs; the same circumstance is observed in the translations of the Scete Patericon and Athanasius of Alexandria’s Homilies Against the Arians. Twofold transmission makes it possible to contrast the features of copying from Glagolitic with those of copying from Cyrillic.
