I can also add that no heretics were to be condemned or subject to any sentences, whatsoever, before been offered at least two chances of renegating their heresies.
In Portugal, for example, very few burnings (Autos-de-Fé) were actually conducted: the majority of the cases were solved with a more or less forced conversion to cristianity (also a more or less truthfull one) or a forced exile to the country of their choice.
Espinosa (dutch philosopher) and David Ricardo (english economist), both of portuguese origins, are perfect examples of how the Inquisition, in Portugal as in Spain, was not quite as it's potraited to be by the Black Legend promoters.
