Ecclesiastical Chronicle, Volume 3

3. After Addai, the proclaimer of the Gospel, Aggai his disciple.

This artisan who wove silk for King Abgar had been raised by him. When his master Addai was killed, he fled to the East and began to preach in all of Persia, Assyria, Armenia, Media, Babylon, and Huzistan original: "ܚܘܙܝܐ" and Gela original: "ܓܠܝܐ", as far as the borders of the Indians. Then he returned to Edessa, because he feared that the faith might vanish from there on account of the paganism of the son of King Abgar. When he arrived in Edessa, the son of Abgar ordered him to weave silk for him just as he had woven for his father. Aggai, however, said to him, "In the time when my master was tending the flock of Christ, I wove for your father. But now that he has committed the hands of the flock of the Church to me, I cannot perform other tasks." Because of this, that pagan became enraged, and he broke his legs and killed him.

4. After Aggai, Mari, another disciple of Addai.

This Mari, when Aggai was killed, departed.

[The Latin translation corresponds to the Syriac text above, describing Aggai’s flight to the East, his preaching in Persia, Assyria, and neighboring regions, and his return to Edessa. It details his refusal to weave silk for the pagan son of Abgar, resulting in his martyrdom by having his legs broken.]

Footnotes explain geographical terms: "Huzistan" (the region of the Huzites near Basra) and "Gela" (the region of Ghilan near the Caspian Sea). It also references the Doctrine of the Apostles regarding the extent of Aggai’s travels and confirms the account of his death as found in historical texts like the History of Armenia by Moses of Chorene.
