Isaac of Ourville
Isaac of Ourville was a medieval French rabbi, author of the mostly-lost Sefer ''haMenahel, a book of halakha''.
Life and Time
Isaac appears to have been a contemporary of Perez of Corbeil ;Isaac cites Moses of Coucy's Semag, from the generation before Perez, while segments of Isaac's Menahel are, in turn, cited alongside the Perez's teachings.
His master was Hayyim of Blois,
who is possibly identical with Hayyim ben Isaac the Frenchman, the author of Ez Hayyim on Jewish monetary law, a disciple of Samuel of Evreux.
Toponym
