Captivity and Martyrdom
The accounts of Luarsab's captivity emphasize his steadfastness in the face of repeated inducements and threats. The shah, according to the tradition, alternately offered him release with treasures and threatened him with death by torture if he would not accept Islam, and the king refused throughout. One incident preserved in the synaxarion records that, during Great Lent, Luarsab declined to eat fish despite the shah's demands, a detail cited as a sign of his strictness in fasting and prayer even under duress.
He was held for several years in chains in Persia and subjected to beatings intended to break his resolve. His execution is described as a strangling carried out on the shah's orders at a fortress in what is now southwestern Iran. The Georgian Orthodox Church numbers him among its royal martyrs, and his commemoration is linked with that of St Archil II, an earlier Georgian king martyred for the faith, with whom he shares a joint feast on January 28.
