Eubulus was a Christian martyr who lived in the early 4th century. He traveled to Caesarea Maritima alongside Adrian of Batanea to provide ministry to the local Christian community. Upon their arrival, the pair was detained by guards acting under the orders of Governor Firmilian. Following their imprisonment and torture, Eubulus was eventually executed for refusing to renounce his faith through idol sacrifice. He is remembered as one of the final martyrs of a long period of persecution in the region.
Life and death

After arriving at the gates of Caesarea, Eubulus and his companion Adrian were immediately arrested for their religious purpose. Following a period of imprisonment and torture, Adrian was executed on 5 March. Two days later, the judge offered Eubulus his freedom if he would perform sacrifices to idols. When he refused, he was martyred, concluding a twelve-year era of persecutions in the city.
Veneration
The saint is commemorated within the Catholic and Orthodox traditions. His feast day is observed on 7 March, two days after the commemoration of his companion, Adrian. He is recognized as a martyr who remained steadfast in his beliefs despite the threat of death.
