Martin de Azpilcueta, Comentario resolutorio de cambios (Salamanca, 1556)

A canon lawyer set out to explain one decretal on usury and, on printed page 85, explained inflation instead: goods and the labour of men fetched far less in Spain before the Indies covered it with gold and silver, the cause being that money is worth more where it is scarce. The quantity theory of money reaches print here, in a commentary on moneylending, twelve years before Bodin.
