Egeria's Diary: Holy Saturday in 4th century Jerusalem

Vigil of Easter.
XXXVIII Now, on the next day, the Sabbath, everything that is customary is done at the third hour and also at the sixth; the service at the ninth hour, however, is not held on the Sabbath, but the Paschal vigils are prepared in the great church, the martyrium. The Paschal vigils are kept as with us, with this one addition, that the children when they have been baptised and clothed, and when they issue from the font, are led with the bishop first to the Anastasis.

2. The bishop enters the rails of the Anastasis, and one hymn is said, then the bishop says a prayer for them, and then he goes with them to the greater church, where, according to custom, all the people are keeping watch. Everything is done there that is customary with us also, and after the oblation has been made, the dismissal takes place. After the dismissal of the vigils has been made in the greater church, they go at once with hymns to the Anastasis, where the passage from the Gospel about the Resurrection is read. Prayer is made, and the bishop again makes the oblation. But everything is done quickly on account of the people, that they should not be delayed any longer, and so the people are dismissed. The dismissal of the vigils takes place on that day at the same hour as with us.
