Berechiah was also a translator, his version being extant of Adelard of Bath's "Quæstiones Naturales", entitled "Dodi ve-Nekhdi" or "Ha-She'elot". He also wrote "Ko'aḥ Avanim", a translation-adaption of a Latin lapidary containing a description of sixty-three species of stones and their magical properties. Besides these works, Berechiah is also said by Zunz to have contributed to the "Tosafot", and, as his name implies, was probably an expert in Hebrew grammar, for which reason he is quoted by Moses ben Issac ha-Nessiah of London, in his "Sefer ha-Shoham." As this work was probably written before 1215, these references confirm the date and place suggested above.
