 This growing interest in animal mechanism and specifically in the Antoniana Margarita was the cause of the second and final edition of the book in 1749, whose preface and permission generously praised Gómez Pereira, and lamented the fact that such an innovator had fallen into total oblivion among the philosophers of his own land. Unfortunately, this new edition did not remedy the prevailing ignorance about him, as one can realize by reading the different works of natural philosophy and the dictionaries produced in Spain at that time, where there are few references to our doctor and they seem to come from indirect sources, not from a direct reading of the text.
