The holy Martyrs Bassos, Eusebios, Eutychios and Basileides lived during the reign of Emperor Diocletian (284-305), and suffered martyrdom in 303. They were wealthy and members of the Senate. They came to believe in Christ and were baptized after witnessing the martyrdom of Bishop Theopemptos of Nicomedia (January 5), who endured with spiritual bravery the horrible tortures to which the pagans had had subjected him.
The idolaters denounced these men as Christians and brought them before the emperor because they refused to worship the gods of the pagans. The Saints showed no fear whatsoever, but boldly proclaimed their faith in Christ and their eagerness to follow the path which would lead to martyrdom.
In the Synaxarion it is stated that the martyrs removed their belts, the symbols of their rank, and then each of them submitted to severe tortures.
Saint Bassos was buried in the ground up to his waist, and his upper body was cut to pieces. Saint Eusebios was suspended head downwards, and his limbs were cut off with axes. Saint Eutychios was tied to four poles by his hands and feet, and he was pulled apart. Saint Basileides was stabbed in the stomach with a knife.
