The prototypes of Athos, Porthos and Aramis - the literary heroes of the popular trilogy by Alexandre Dumas "The Three Musketeers", "Ten Years Later" and "Twenty Years Later" were real people.
Athos (his real name is Armand de Sellec d'Atoe d'Auteville) came from a merchant family that received the nobility. He was the royal musketeer and during the time of Louis XIII took part in all the wars waged by the king and cardinal Richelieu. He died in Paris in 1643.
Porthos - Isaac de Porte - was born in 1617 and was a royal notary. De Porte served in the company of the Musketeers a year after the death of Athos, and therefore they could not have known each other.
Aramis - Gascon by birth, the son of an officer, in fact was called d'Aramis. He also served in the Musketeer Company and died in 1650.
D'Artagnan was actually called Charles de Bas d'Artagnan, born in the early 17th century in Gascony. Having achieved honors and awards, he got married, but within six years only twice visited his wife, who in protest went to the monastery.
In April 1673, in a battle with the Dutch, d'Artagnan died, as reported by the then newspapers.
