By the 5th century, a legend had arisen that Jacob of Nisibis scaled a mountain in search of Noah's Ark. As related by Faustus of Byzantium, Jacob and his party traveled to the mountains of Armenia, and "came to Sararad mountain which was in the borders of the Ayraratean lordship, in the district of Korduk'." Near the summit, an angel visited him in his sleep, instructing him to climb no further. In consolation, the angel provided Jacob with a board taken from the Ark. Jacob brought the artifact back to the city, which is said to have preserved the relic ever since. Agathangelos relates a similar story, although not directly related to the Ark, in which the 3rd century Armenian king Tiridates scales Masis and brings back eight rocks to use in the foundation of new churches.
