The lectionary manuscript is described in Wright's catalogue 1:154-159 as number CCXXIV. Information on readings has been taken from there: Vellum 11 inch by 8,375 inch. 139 folios. 22-32 lines. Stiff formael Estrangelo. Dated by colophon to 1000 CE (A. Gr. 1311). This is a Jacobite Lectionary containing lessons from the OT and the NT arranged by Athanasius V, patriarch of Antioch between 987 and 1003 CE.

Note in Estrangello on fol. 139a "This lectionary belongs to the holy church of the glorious and holy Mar Barsauma; may his blessing be upon the sinner who wrote (this) according to his ability, Constantine, etc"

Next to it note in small cursive characters: Whosoever reads, let him pray for the sinner Yeshua, full of faults and sores, who read in it; who in the year 1533 (A.D. 1222) was persecuted in the holy church of Mar Bar-sauma in Antioch. And there was with me a man, who feared God more than all of us, Rabban Jacob, of the convent of Mar Bar-Sauma, and he strengthened and comforted me, etc
