Just a small not on Pedro Nunes - he was not a Jew who converted to catholicism (he was catholic, though - in 1548 he was even knighted with an honorific catholic order by the King of Portugal), he was a New Christian of Jewish origin, that is to say, someone whose ancestors (no one knowns if recent of distant) were Jewish and converted or were forced to convert to catholicism. He never had problems with the Portuguese Inquisition, although two of his grandsons were arrested, Matias Pereira from 1623 to 31 and Pedro Nunes Pereira from 1623 to 32 (they were both released alive and given back their properties, though, which was quite rare).
