He delivered a fervent address on the conversion of England, which led to a decree being passed by the chapter, urging provincials and priors to do all they could to receive English, Irish, and Scotch novices into the order, with a view to its preservation in those countries.

He also founded at Vilvoorde a convent of nuns of the Second Order of Saint Dominic, which later moved to Carisbrooke on the Isle of Wight.

He died in the twentieth year of his cardinalate, at the age of 64, and was buried in his titular church of Santa Maria sopra Minerva at Rome.
