Leontine martyrs

The Leontine Martyrs were a group of people who were killed after a long period of captivity in Persia. They were executed by the order of King Yazdegerd II in 455, five years after the insurrection led by Vartan Mamikonian. The group is named after Leontius of Vanand (In Armenian Սուրբ Ղևոնդ, pronounced "Surb Ghevond"), the most senior of the religious group.

Abraham of Arazd.
Abraham of Arazd was an Armenian priest and a disciple of the Leontine martyrs. Like his teachers, he was subjected to prolonged torture, but unlike them, was eventually set free. 
He afterward left society to become a hermit, remaining one until his death in the 5th century. He is regarded as a saint by the Armenian Church, with a feast day of December 20.
