 Botarel was one of those who attended the disputation at Tortosa (1413–1414), and he is said to have written a polemic against Geronimo de Santa Fe.In 1409, at the request of the Christian scholar Maestro Juan, Botarel composed a commentary on the Sefer Yezirah.In the preface, he excuses himself for having revealed the divine mysteries of this work to Maestro Juan by quoting the saying of the sages that a non-Jew who studies the Torah is equal to a high priest.
