Thesis (Ph. D.)--Columbia University, 1940. / Vita. "As originally planned this book was to present two separate units of work on the Loherain cycle. It was decided later, however, to print only the study below ... The unprinted material consists of the text of follos 76d-81c (lines 10823-12438) of Gilbert de Mes in the Berne manuscript, with variants of eight other manuscripts. This material, including several pages of introduction of an explanatory nature and a complete bibliography on Gilbert de Mes, is to be found in the Library of Columbia university."--Pref. Published also without a thesis note. Bibliography: p. 149-156.
