At Rome some objection was still made to his extreme youth; but he hastened thither, and delivered before the pope a Latin harangue, which scattered all objections to the wind.

After consecration at Rome, in 1607, he returned to Paris, and hastened to take possession of his see of Lucon, "the poorest and the nastiest in France," as he himself said.

He could support poverty, but he also set great store by riches, and he was seriously anxious for the expenses of his installation.

"Taking after you, that is, being a little vain," he wrote to one of his fair friends, Madame de Bourges, with whom he was on terms of familiar correspondence about his affairs, "I should very much like, being more easy in my circumstances, to make more show: but what can I do?
No house; no carriage; furnished apartments are inconvenient; I must borrow a coach, horses, and a coachman, in order to at least arrive at Lucon with a decent turn-out." He purchased second-hand the velvet bed of one Madame de Marconnay, his aunt; he made for himself a muff out of a portion of his uncle the Commander's martenskins.

Silver-plate he was very much concerned about.
"I beg you," he wrote to Madame de Bourges, "to send me word what will be the cost of two dozen silver dishes of fair size, as they are made now; I should very much like to get them for five hundred crowns, for my resources are not great.
