31. The rite of the greater entrance when a patriarch or a metropolitan celebrates Mass is described by Christianus Lupus, Operum super Conciliis, pt. 3, p. 760 of the Brussels edition. In his Vocabulario Ecclesiastico under the word Prothesis, Magri describes in detail the actions performed by the Emperor while standing at the sacred assembly on the day of his coronation as emperor. Goarius explains most carefully the complete ceremony of the greater entrance in his in notis ad Liturgiam Sancti Joannis Chrysostomi, no. 110, as does Cardinal Bona in Rer. Liturgic., bk. 2, chap. 9, no. 4. Everything done by the Greeks on this occasion is likewise done by the Armenians, Copts, Ethiopians, and Syrian Jacobites, as can be seen in Le Brun, Explanatione Missae, vol. 3; in Chardon, Historia Sacramentorum, vol. 2, chap. 2; and in Renaudot, vol. 1, on in notis ad Liturgiam Cophtorum. Why, even in the city of Rome, on the feast of St. Athanasius, the Greeks may be seen in their own church performing all the ceremonies We have reviewed above. "And in this way even today the Greeks perform the liturgy on the feast of St. Athanasius in his basilica in Rome" (Lupus, loc. cit.).
