Celestine IV

He died on the 22nd of August 1241, while Frederick II. was advancing against him, and was succeeded by Celestine IV.

Celestine IV. died after eighteen days, and this time, in spite of the seclusion of the cardinals, there was an interregnum of twenty months.

From his master Buonamico had the portraits of Pope Celestine IV. and Innocent IV., both of which he afterwards introduced in the paintings which he made in S. Paolo a Ripa d'Arno at Pisa.

If the claim of the Castillione ancestry be allowed the archives of the race would be still farther enriched by the name of Pope Celestine IV.,
