Holy Martyrs Isaac, Apollos and Quadratus were pagans who served at the
court of the emperor Diocletian (284-305). They were among the
spectators who witnessed the sufferings of the Holy Great Martyr George
His faith, valor and miracles caused them to believe in Christ. The
saints openly declared themselves Christians, and reproached the emperor
for his impiety and cruelty. They were sentenced to death. The martyr
Quadratus was beheaded with a sword, and the martyrs Apollos and Isaac
perished by starvation (+ 303).
