Mentelin, the first Strassburg printer, used a gothic type which pointed towards roman in his Biblia Latina, finished in 1460. [...] But the font of the 'R Bizarre,' as it is often called, was the first roman letter used in Germany. [...] This ungainly roman type was used by Adolph Rusch of Ingweiden ('the R Printer'), who printed in it an edition of the Rationale of Durandus, at Strassburg, as early as 1464.
