 His generosity to the poor was renowned, and although his income was small, he daily distributed among them bread, money and even remedies, such as quinquina, then newly discovered, which the people at Rome used for a time to call Lugo's powder.The works of Juan de Lugo, some of which have never been printed, cover nearly the whole field of moral - and dogmatic theology.The first volume, "De Incarnatione Domini" (Lyons, 1633), of which the short preface is well worth reading to get an idea of de Lugo's method, came out in 1633.
