The Coptic Church celebrates the Feast of the Cross on the 17th of Tut (27 September) and on the 10th of Baramhat (19 March). The first date commemorates the discovery of the Cross by Queen Helena, the mother of the Great, in the fourth century. The second date commemorates the recovery of the Holy Cross from the by the Roman Emperor in the seventh century. Although these two are Byzantine par excellence, the Coptic Church has a special rite for these days. The tune of Palm Sunday is used for these as well as for the procession.

There is a praising King Constantine, who ordered the closing down of the idol temples and the reopening of the churches of the Christians. It seems that the cult of was imported from the Byzantine church.
