Byblo Apostolos. A 36-folio fragment of the apostolos (acts and epistles of Christ's apostles) found in the village of Byblo near Peremyshl and, most probably, transcribed there in the late 13th–early 14th century from the Church Slavonic text. It contains many peculiarities of the Ukrainian southwestern dialects at that time. The apostolos was researched and published by P. Kopko in Denkschriften der Wiener Akademie, Phil.-hist. Klasse, 55 (Vienna 1912).
