The Company of Martyrs
The June 7 commemoration gathers a substantial group rather than a single saint. Named with Sisinius are the deacon Cyriacus and the martyrs Smaragdus, Largus, Apronian, Saturninus, Crescentian, Papias, and Maurus, together with the women Priscilla and Lucy and Artemia, identified in the tradition as the emperor's daughter. The synaxarion associates their deaths with the persecution of Diocletian and Maximian and the reigns of their successors.
The deacon Cyriacus, named among Sisinius's companions, is also honored in the Western calendar, where he is commemorated on August 8 with Largus and Smaragdus and remembered as a deacon of the Roman Church under Popes Marcellinus and Marcellus. Western tradition associates Cyriacus with charitable service to Christians compelled to labor on the Baths of Diocletian and with the healing of Artemia, a daughter of Diocletian, before his own martyrdom by beheading on the Via Salaria.
