of Chrysopolis. Fate Due to the intervention of Flavia Julia Constantia, Constantine's sister and also Licinius' wife, both Licinius and Martinian were initially spared, Licinius being imprisoned in Thessalonica, Martinian in Cappadocia; however, Constantine seems to have soon regretted his leniency as both former emperors were subsequently executed. Martinian was probably executed in the spring of 325, in Cappadocia. Notes References DiMaio, Michael, "Licinius (308 – 324 A.D.)", DIR (1997).
