St. Bonaventura was educated in Paris under Alexander Hales, the Irrefragable Doctor, and in 1245, at the age of twenty-four, became a Professor of Theology in the University. In 1256 he was made General of his Order; in 1273, Cardinal and Bishop of Albano. The nuncios of Pope Gregory, who were sent to carry him his cardinal’s hat, found him in the garden of a convent near Florence, washing the dishes; and he requested them to hang the hat on a tree, till he was ready to take it.
