A Greek inscription found in the excavation of the Nea commemorates the completion of the church in 543 C.E. While the inscription praises Justinian for carrying out the project, it also mentions that Constantinus, the abbot of the church’s monastery, supervised the work. The inscription was carefully framed by a tabula ansata with its flanking triangular handles. A more detailed description of the church appears in the sixth-century account of the Byzantine court historian Procopius.
