Mariana, therefore, and other authors who follow him, err in stating that Caesar, Rodrigo's second son, was older than his brother Giovanni.

In reality, Giovanni must have been two years older than Caesar.

Venetian letters from Rome, written in October, 1496, describe him as a young man of twenty-two; he accordingly must have been born in 1474.[6] Lucretia herself came into the world April 18, 1480.

This exact date is given in a Valencian document.

Her father was then forty-nine and her mother thirty-eight years of age.
