Considering the character of the Roman curia in the Middle Ages it would scarce be malicious to suggest that the chief object of these prohibitions was to create a market for licenses to violate them, and St. Antonino of Florence, about the middle of the fifteenth century, tells us that as a rule the Venetian merchants had them (S. Antonini Confessionale)
In spite of his laxity in practice, Alfonso X in the Partidas embodies the Lateran decree denouncing slavery for all who aid the Saracens in any manner (Partidas, P. IV, Tit. xxi, ley 4) and in 1253 he admitted papal control in such matters by obtaining in advance from Innocent IV ratification of certain treaties which he was negotiating with the princes of Africa (Fernández y González, p. 337).
