There can be no doubt that Desmond was jealous of James Fitzmaurice; and historians well-affected to the Geraldines have attributed the latter's rebellion to the ill-feeling existing between them. It is said that Lady Desmond, who was a Butler, had prevented her husband from making any provision for his distinguished kinsman. It was reported to Drury that Fitzmaurice had called himself Earl of Desmond on the Continent, and that this would be sure to annoy the Earl, whose pride was overweening. But this does not seem to have been the case. Fitzmaurice is not called Earl either in his own letters or in those written to him. The general of the Jesuits addresses him as 'the most illustrious Lord James Geraldine'; the Pope speaks of him as James Geraldine simply, and so he calls himself, sometimes adding 'of Desmond.' But that he should have been appointed general of a force which was to operate in Desmond's country was quite enough to excite suspicion. No sooner did the news of his arrival reach the Earl than he wrote to tell Drury that he and his were ready to venture their lives in her Majesty's quarrel, 'and to prevent the traitorous attempts of the said James.' He had nevertheless been in correspondence with Fitzmaurice, and had urged his immediate descent upon the Irish coast some eighteen months before.[17] [Sidenote: Nicholas Sanders, the Jesuit.] Not less important than Fitzmaurice was Dr. Nicholas Sanders, who acted as treasurer of the expedition. He was known by the treatise _De Visibili Monarchia_ which Parker said was long enough to wear out a Fabius, and almost unanswerable, 'not for the invincibleness of it, but for the huge volume.' Answers were nevertheless written which no doubt satisfied the Anglican party, but the Catholic refugees at Brussels thought so highly of Sanders that they begged Philip to get him made a cardinal.
