[1] A dedicatory inscription appears on the tympanum: By the grace of Christ, I, Vacë, son of Sargis, and my wife Mamaxatun, daughter of Abuserh, we built this hall of relics in this monastery of Horomos, under the prelature of Ter Barsel, son of Amir Erkat', and we gave in present at the library the vineyard that we had bought in Awsakan, for the office and for the relic.
In exchange, the monks of this chapter granted us the mass of the first Sunday after Easter in the churches of this place.
And we gave further the vineyard of Pasakan hol, and the one who will ensure regularly our masses will have free disposal of wine.
