Strictly speaking, there is only one festival of encaenia in the ancient Church reported by our ancient or modern authorities on the subject, the feast of the dedication of the Church of the Holy Sepulchre in Jerusalem, instituted on 13 September 335 to mark the tricennalia of the emperor Constantine, and described for us by Eusebius in his Life of Constantine. The rebuilding of churches after the persecution under Diocletian, and a similar encaenia of the Church of Tyre are even more fully recorded in the tenth Book of the History. Both dedications were accompanied by a long panegyric of the emperor, delivered by Eusebius himself, extolling Constantine as a second Solomon, and were the occasion for similar festive addresses and theological discourses from other visiting ecclesiastical dignitaries: but, apart from the magnificence of the occasion, the public banquets, the vast concourse of delegates from every part of the Christian world (Eusebius seems to be as anxious as Luke in his account of Pentecost in Acts ii. to emphasise the ecumenical character of the occasion), there is nothing unexpected in any of the rites or ceremonies performed at the encaenia; in addition to the celebration of the Eucharist, they consisted for the most part of prayers for the general peace, for the Church of God and for the emperor, Scripture readings, singing of psalms, and the lavish distribution of alms.
