No writings of Jacob of Nisibis are known, although he has been confused in the past
<ref group="note">[[w: Gennadius of Massilia| Gennadius]] speaks of Jacob as a copious writer, and gives the titles of twenty- six different treatises of which he was the author. <br> :"These, or some of them, eighteen in number, were found by [[w:Giuseppe Simone Assemani|Assemani]] in the [[w: Mechitarists| Armenian convent of St. Anthony at Venice]] ...The titles of these treatises - ''De Fide, De Dilectione, De Jejunio, De Oratione, De Bello, De Devotis, De Poenitentia, De Resurrectione,'' etc. - correspond generally with those given by [[ w:Gennadius of Massilia|Gennadius]], but the order is different. In the same collection he found the letter of Jacob to the bishops of Seleucia and Ctesiphon, on the Assyrian schism. It is a lengthy document, in thirty- one sections, lamenting the divisions of the church and the pride and arrogance which were their cause, and exhorting them to study peace and concord. These were all published with a Latin translation and a learned preface establishing their authenticity and notes by [[w: Nicolò Maria Antonelli| Nicholas Maria Antonelli]] in 1756. They were also printed in the collection of the [[w: Mechitarists| Armenian fathers]], published at Venice in 1765, and again at Constantinople in 1824. The Latin translation is found in the ''Patres Apostolici'' of [[ w:Armand-Benjamin Caillau|Caillau]], tom. 25, pp. 254-543. " ( Sir William Smith.

Murray, 1882. p. 326.)</ref> with the fourth century Persian writer [[w:Aphrahat|Aphrahat]] (ca.270-ca.345), who composed a series of twenty-three expositions or homilies on points of Christian doctrine and practice.
The author of the homilies, who was earliest known as "the Persian sage", was a Persian subject, and tells us that he took the Christian name ''Jacob'' at his baptism. Hence he was already confused with Jacob of Nisibis by the time of [[w:Gennadius of Massilia|Gennadius]] (before 496), and the ancient Armenian version of nineteen of the homilies was published under this latter name.
The most famous miracle of St. Jacob was that by which he protected the city of Nisibis from the Persians, as is related by [[Theodoret of Cyrrhus|Theodoret]] both in his religious and ecclesiastical history, by [[Theophanes the Confessor|Theophanes]], and even by [[w:Philostorgius|Philostorgius]] himself, who was a rank Arian, and cannot be suspected of being too favourable to St. Jacob.
After [[Constantine the Great]] died in the year 337 and his sons had taken over the kingdom, the Persian king [[w:Shapur II|Shapur II]] (309-379) besieged Nisibis three times over, during his war against the Romans.<ref group="note">From 337-350, the Persian King [[w:Shapur II|Shapur II]] attacked Nisibis on three occasions, as it was the great city of Northern Mesopotamia and the bulwark of the eastern provinces. The first Siege of Nisibis took place in A.D. 338; the second in A.D. 346; and the third in A.D. 350, lasting three months.</ref> St. Jacob and St. [[Ephrem the Syrian|Ephraim]] prayed with the people in the church each time, asking God to help them. The bishops' intercession during the final siege in 350 saved the city:<ref group="note">The tale of the final siege of 350, which lasted three months, and of the bishop's successful efforts to save his city, can be read in the passages of [[w:Edward Gibbon|Gibbon]] (ch. xviii. vol. ii. pp.385ff.), or [[w:Auguste-Théodore-Paul de Broglie|de Broglie]] (''L'Eglise et L'Empire'', tom. iii. pp.180-195.).</ref>
:The bishop would not pray for the destruction of any one; but he implored the divine mercy that the city might be delivered from the calamities of so long a siege. Afterwards, going to the top of a high tower, and turning his face towards the enemy, and seeing the prodigious multitude of men and beasts which covered the whole country, he said: “Lord, thou art able by the weakest means to humble the pride of thy enemies; defeat these multitudes by an army of gnats.” God heard the humble prayer of his servant, as he had done that of [[Moses]] against the Egyptians, and as he had by the like means vanquished the enemies of his people when he conducted them out of Egypt. For scarcely had the saint spoken those words, when whole clouds of gnats and flies came pouring down upon the Persians, got into the elephants’ trunks, and the horses’ ears and nostrils, which made them chafe and foam, throw their riders, and put the whole army into confusion and disorder. A famine and pestilence which followed, carried off a great part of the army; and Sapor, after lying above three months before the place, set fire to all his own engines of war, and was forced to abandon the siege and return home with the loss of twenty thousand men.<ref name="BARTLEBY">[http://www.aol.bartleby.com/210/7/111.html St. James, Bishop of Nisibis, Confessor] at Bartleby.com.</ref>
