Scriptors Tres [the three writers].
Meaning Richard of Cirencester, Gildas Badonicus, and Nennius of Bangor. Julius Bertram, professor of English at Copenhagen, professed to have discovered the first of these treatises in 1747, in the royal library of that city. Its subject is De Situ Britanniæ, and in 1757 he published it along with the two other treatises, calling the whole The Three Writers on the Ancient History of the British Nations. Bertrams forgery was completely exposed by J. E. Mayor, in his preface to Ricardi de Cirencestria Speculum Historiale. (See SANCHONIATHO.)
