The fast of the Great Sabbath was to be continued through the night, as prescribed in the Apost. Const. V. 19: “Continue until cock-crowing and break off your fast at dawn of the first day of the week, which is the Lord’s day, keeping awake from evening until cock-crowing: and assembling together in the Church, watch and pray and beseech God, in your night-long vigil, reading the Law, the Prophets, and the Psalms, until the crowing of the cocks: and after baptizing your Catechumens, and reading the Gospel in fear and trembling, and speaking to the people the things pertaining to salvation, so cease from your mourning.” A chief reason for the watching was that Christ was expected to return at the same hour in which He rose. On the meaning of “superposition” see Routh’s note on the Synodical Epistle of Irenæus to Victor of Rome (Rell. Sac. ii. p. 45, ss.), and the passage of Dionysius of Alexandria there quoted.
