Note 81 — Chapter V
Reading edition
Sismondi's account of these facts is strangely inaccurate. One page of his seventy-first chapter contains these four misstatements: 1. That Federigo was son of Bernardino della Carda by the Countess of Urbino; 2. That he married, about 1444, a daughter of Francesco Sforza; 3. That 20,000 florins was the price of both fiefs; 4. That Fossombrone was gifted to Federigo by Sforza. I have not found an authority for any one of these assertions.
