Just a quick note on a recent update: A reader of this blog has drawn our attention to a digitisation of the 1545, Diego Hernández, Zaragoza edition of the Tragicomedia at the Biblioteca Digital Memoria de Madrid. Thanks to him we are, thus, able to provide you with a new title page at the relevant post, and a new link at our links section.
