Vous avez dit que Saint Sylvestre a vécu très longtemps. Quel age avait-il à sa mort? Merci de votre réponse.

Et la date de naissance?

Google is your friend.

Not in this case Chris! Google wasn't around then, and records weren't so accurate back then either apparently. His birth date appears to be "sometime after 280" or "the late 280s" and date of death might have been around 335 to 337. Which would have made him anywhere between 46 and 57 when he died. So not a real long life by modern day standards.
