Saint Juliana of Nicomedia suffered Christian martyrdom during the Diocletian persecution in 304. She was popular in the Middle Ages as the patron saint of sickness.
Saint Stephen (†c.34), venerated as the protomartyr or first martyr of Christianity, was, according to the Acts of the Apostles, a deacon in the early church at Jerusalem who aroused the enmity of members of various synagogues by his teachings. Accused of blasphemy at his trial, he made a speech denouncing the Jewish authorities who were sitting in judgment on him and was then stoned to death.
