No founder, founding act or inception year is on record. The Greek Orthodox Archdiocese of America says the Church has kept Great Friday, Great Saturday and Pascha as an annual commemoration from the beginning, and when the pilgrim Egeria wrote about Jerusalem on a journey scholars place between 381 and 384, the day already ran from a morning veneration of the Cross to an evening reading of the burial.
Three hours in the open air
The veneration ran until the sixth hour. Then the crowd moved into the court between the Cross and the Anastasis, in rain or in heat, and for three hours nothing was done but the reading of lessons. Psalms, the Apostle, the Gospels and the prophets, arranged so that the prophecy and the fulfilment sat side by side.
The 1919 English edition adds a note to that passage. It is probably the earliest record we have, it says, of the observance of the Three Hours.
