In the metrical life of Celestine V. by the cardinal of St. George (Muratori, tom. iii. P. i. p. 613, etc.), we find a luminous, and not inelegant, passage (l. i. c. 3, p. 203 etc.): —
___genuit quem nobilis Ursae (Ursi?)
Progenies, Romana domus,veterataque magnis
Fascibus in clero, pompasque experta senatûs,
Bellorumque manû grandi stipata parentum
Cardineos apices necnon fastigia dudum
Papatûs iterata tenens.
Muratori (Dissert. xlii. tom. iii) observes, that the first Ursini pontificate of Celestine III. was unknown: he is inclined to read Ursi progenies.
