 Banduri never published these works, though as late as 1722 he announced, as near at hand, their appearance in four folio volumes.In the meantime, he was attracted by the rich treasures of Byzantine manuscript and other material in the Bibliothèque Royale and the Bibliothèque Colbert.In 1711 he published at Paris his De Administrando Imperio ("Imperium Orientale, sive Antiquitates Constantinopolitanae"), a documentary illustrated work on the Byzantine Empire, based on medieval Greek manuscripts, some of which were then first made known.
