^Martyr Eusebius lived during the reign of Diocletian (284-305 AD) and was a courtier of the Senate. He converted to Christianity during the witness of Bishop
Theopemptus in Rome († 5 January), when he saw the spiritual prowess of that Saint during his tortures, and the miracles that he performed. Because he became a Christian he was arrested and led before the Emperor, where he confessed his faith in Christ. He was martyred with horrible tortures and was partitioned with an axe in the year 298 AD.
^The Life-giving Spring of the
Mother of God was revealed to Leo on April 4, 450. Leo later became Byzantine Emperor Leo I (457-474).
^Fabian succeeded St Antherus as Pope of Rome in 236 and was martyred in 250 under Decius. St Cyprian described him as an 'incomparable man' and added that the glory of his death matched the purity and goodness of his life.
^According to his Life, he was an officer in the imperial army and a favourite of Diocletian. Nevertheless, when he was discovered to be Orthodox no mercy was shown him. Tied to a tree, his body was made a target for Roman archers and he was finally martyred with clubs. His church is one of the seven main churches in Rome.
^Born in Connaught in Ireland, he founded several monasteries. His name is connected with Fobhar (Fore) in Westmeath. Ecclefechan and St Vigean's near Arbroath in Scotland are also called after him.
