The original Greek text of the Apostolic Tradition has survived only in fragments; but the full Greek text circulated widely in the Eastern churches from the 4th century onwards, and is consequently found in translation in three ancient collections of the Church Orders, the Alexandrine Sinodos, the Aksumite Collection and the Verona Palimpsest. The Alexandrine Sinodos was re-discovered in the 19th century: a Bohairic Coptic version was published in 1848 by Tattam, the earlier Sahidic Coptic version was published in 1883 by Paul de Lagarde, the Ethiopic and Arabic versions in 1904 by George William Horner. The text found in the Sahidic version was named by the publishers "Egyptian Church Order" and corresponds to what is now usually known as "Apostolic Tradition".
