I have spoken about the Coptic Synaxarium in different places (search under Coptic Synaxarium). Here, I just would like to put up links to the Coptic Synaxarium, extant in Arabic, to ease research. It was published, with a French translation, by Réne Basset (1848-1924), the famous French Orientalist, in Patrologia Orientalis (P.O.), from 1907 to 1923, under the title Synaxaire Arabe-Jacobite. Five volumes of P.O., tomes 1, 3, 11, 16, and 17, included the 13 Coptic months.
P.O. Tome 1 (1907): Mois de Tout et de Babeh
P.O. Tome 3 (1909): Mois de Hatour et de Kihak
P.O. Tome 11 (1915): Mois de Toubeh et d’Amchir
P.O. Tome 16 (1922): Les mois de Baramhat, Barmoudah et Bacans
P.O. Tome 17 (1923): Les mois de Baounah, Abib, Mésoré et jours complémentaires
