Note 135
Paul Warnefrid (de Gestis Langobard. 1. iv. c. 44, p.
853, edit. Grot.) allows that Arianism still prevailed under
the reign of Rotharis (A.D, 636-652). The pious Deacon does
not attempt to mark the precise era of the national
conversion, which was accomplished, however, before the end
of the seventh century.
