Question moral si el chocolate quebranta el ayuno eclesiastico. : Tratase de otras bebidas i confecciones que se vsan en varias provincias.
A 1636 Spanish treatise printed in Madrid by the widow of Juan Gonçalez, questioning whether chocolate breaks the ecclesiastical fast and surveying other drinks and confections used in various provinces. The title page has an engraved architectural frame with a crowned coat of arms, a central figure in a niche, and dense lettering in black ink. The second picture shows a plain endpaper with a pasted bookplate of two oval portraits and a coat-of-arms label, a detail useful for ex-libris or vintage ephemera layouts.
