[1] The man subsequently known as Juan Andrés was born in Xàtiva, Spain, the son of an Islamic scholar.
Trained as a faqīh himself, he converted to Catholicism in 1487 and was baptised in Valencia Cathedral, taking the Christian name Juan Andrés.
Becoming a priest, he was made an envoy by the Catholic Monarchs Ferdinand and Isabella, to preach Christianity in Granada after it was reconquered.
[5] Juan Andrés' main apologetical work, Confusion de la secta mahomatica y del alcoran (Valencia, 1515), while written to encourage Muslims to convert to Christianity, was later banned by the Spanish Inquisition due to the extensive quotations from the Qur'an that it contained.
It was translated from Spanish into Dutch as Een zeer wonderlycke ende waerachtighe historie van Mahomet (Antwerp, 1580), and from Latin into German as Confusio Sectae Mahometanae: darinnen deß Mahomets Ursprung, Ankunfft, Leben vnd Tod (Leipzig, 1598).
