The life of David and Constantine of Yaroslavl
Constantine seems to have died earlier than his brother, though the sources do not agree on how.
Father and sons together were the first princes of the Yaroslavl line to be honored as saints of the whole Russian Church, their veneration growing directly out of the household's shared holiness rather than any one man's alone. Their relics were found together in a single grave in 1463, Theodore himself a man of notable height, his two sons laid at his side both shorter in stature. David and Constantine keep their commemoration on the anniversary of their father's death and again in early spring, on the day their relics were uncovered together at Yaroslavl.
They are remembered less for deeds recorded of each individually than for having stood, with their father, at the founding of the city's line of holy princes.
