1096 Crusade to Jerusalem. Chookaszian's hypothesis is based on the assumption that like most prominent Crusaders of the time, Sinclair married an Armenian. The approximate dates of Roslin's birth and death can be determined using the dates of his manuscripts. Based on the following it can be assumed that Roslin was at least 30 in 1260. At the time one could only achieve the level of mastery displayed in the Zeytun Gospel of 1256 no earlier than in their mid twenties. In the colophon of the Gospel of 1260, Roslin mentions that he has a son, indicating that he was likely a priest since a monk would have no children while a member of the laity would likely not have been an illuminated manuscript painter. By the time of the Gospel of 1265, Roslin already had his own apprentices. Roslin painted two portraits of prince Levon, the earliest of which was executed in 1250 (the prince was born in 1236) and the second in 1262 showing the prince with his bride Keran of Lampron. Roslin's name isn't seen on any manuscript dated after 1286 and he most likely died in the 1270s. None of Roslin's contemporaries or his pupils refer to him in their work and in the following centuries, his name is only mentioned once when the scribe Mikayel working in Sebastea in the late 17th century found in his monastery a gospel book illustrated in 1262 by the "famous scribe Roslin" which he later copied. Manuscripts Signed by Toros Roslin Seven manuscripts have been preserved that bear the signature of Roslin, they are made between 1256 and 1268 five of which are copied and illustrated by Roslin. Of these four are owned by the Armenian Patriarchate of Jerusalem located in the Cathedral of St. James. These include the Gospel of 1260 (MS No. 251) copied for Catholicos Constantine I. The Gospel of 1262 (MS No. 2660) was commissioned by Prince Levon, during the reign of King Het’um (I, 1226 to 1270), copied at Sis by the scribe Avetis, illustrated by Roslin at Hromkla and bound by Arakel Hnazandents. The Gospel of 1265 (MS No. 1965) was copied for the daughter of Constantine of Lampron, lady Keran who after the death of her husband Geoffrey, lord of Servandakar, retired from the world. Mashtots (MS No. 2027) was commissioned in 1266 by bishop Vartan of Hromkla, copied by Avetis who
