[Footnote 45: In describing the fall of the Colonna, I speak
only of the family of Stephen the elder, who is often
confounded by the P. du Cerceau with his son. That family
was extinguished, but the house has been perpetuated in the
collateral branches, of which I have not a very accurate
knowledge. Circumspice (says Petrarch) familiae tuae statum,
Columniensium domos: solito pauciores habeat columnas. Quid
ad rem modo fundamentum stabile, solidumque permaneat.]
