Yet this 'pale rider' notched up two marriages, a number of sons and was the father of Constantine the Great. His first wife Helena would later become the first known Christian tourist and claimed to have found the burial chamber of Jesus in Jerusalem. For that she got a sainthood and an island named after her in the South Atlantic where later another emperor Napoleon would die in self pitying exile. So though Constantius remains a tiny footnote', his son and first wife would achieve a greater immortality in future centuries.
