Et scribatur viro nobili ser Angelo Venerio, consuli nostro Sibilie. Acción consular, comunicación diplomática y estrategia mercantil veneciana en Castilla a principios del siglo XV

The present article proposes the edition and study of the only letter sent by a Venetian consul in Castile found until now. We reconstruct the life course of its author, Angelo Venier, and Luca Falier's, a Venetian merchant with interests in Andalusia, named in the letter. The richness of contents allows us to deal with many different and complex issues, such as Venetian private navigation in the Iberian peninsula; juridical mechanisms for the resolution of conflicts between foreign merchant nations in Castile; the Genoese situation; Venetian perspectives in Andalusia; and merchant and private businesses of other Venetians in Seville. The image that arises is much more detailed than what we knew up to this moment.
