The second declares Giovanni Borgia instead to be the son of Pope Alexander VI himself and runs: "Since you bear this deficiency not from the said duke, but from us and the said woman, which we for good reasons did not desire to express in the preceding writing". The pope was forbidden by canon law to publicly recognize children and did not wish that Giovanni Borgia should suffer in his inheritance as a consequence.
The second declaration states that Giovanni Borgia is the son of Pope Alexander VI. It explains that this fact was not due to the Duke but rather because of the Pope and the woman involved, who were not willing to publicly acknowledge it in previous writings. The pope was forbidden by canon law from publicly acknowledging children and did not want Giovanni Borgia to suffer as a result.
