Pope Innocent, who had carried on violent war against the emperor Frederic, and had endeavored to dispossess him of his Italian dominions, still continued hostilities against his grandson; but being disappointed in all his schemes by the activity and artifices of Mainfroy, he found that his own force alone was not sufficient to bring to a happy issue so great an enterprise.
He pretended to dispose of the Sicilian crown, both as superior lord of that particular kingdom, and as vicar of Christ, to whom all kingdoms of the earth were subjected; and he made a tender of it to Richard, earl of Cornwall, whose immense riches, he flattered himself, would be able to support the military operations against Mainfroy.

As Richard had the prudence to refuse the present,[*] he applied to the king, whose levity and thoughtless disposition gave Innocent more hopes of success; and he offered him the crown of Sicily for his second son, Edmond.[**] Henry, allured by so magnificent a present, without reflecting on the consequences, without consulting either with his brother or the parliament, accepted of the insidious proposal, and gave the pope unlimited credit to expend whatever sums he thought necessary for completing the conquest of Sicily.

Innocent, who was engaged by his own interests to wage war with Mainfroy, was glad to carry on his enterprises at the expense of his ally: Alexander IV., who succeeded him in the papal throne, continued the same policy, and Henry was surprised to find himself on a sudden involved in an immense debt, which he had never been consulted in contracting.

The sum already amounted to a hundred and thirty-five thousand five hundred and forty-one marks, beside interest;[***] and he had the prospect, if he answered this demand, of being soon loaded with more exorbitant expenses if he refused it, of both incurring the pope's displeasure, and losing the crown of Sicily, which he hoped soon to have the glory of fixing on the head of his son.
