The Plato MS. designated by Bekker as Ω and by Burnet as O escaped the investigation of editors of the text of Plato for nearly a century, because it was wrongly cited by Bekker as Vat. 796. Finally, in 1908 Rabe published an account of the missing MS., which he had discovered in the Vatican library listed as Vat. gr. 1. Until its rediscovery the opinion of Jordan prevailed that it was a comparatively late MS., copied from A (Parisinus graecus, 1807). It actually belongs, however, to the late ninth or early tenth century—i.e. it is of almost equal age with A and B.
