Armand, Seigneur de Sillègue, d'Athos, et d'Autevielle ("Lord of Sillègue, Athos, and Autevielle"), better known as Armand d'Athos (c. 1615 – December 21, 1643), was a Gascon Black Musketeer[1] of the Maison du Roi in 17th-century France.
He took his name from the small market town of Athos-Aspis on the Gave d'Oloron, close to Sauveterre-de-Béarn and Autevielle.
[3][4] He served as the inspiration for Alexandre Dumas's character Athos in The d'Artagnan Romances.
[3] After joining the Musketeers of the Guard in 1640, Athos maintained his friendship with d'Artagnan.
[3] Athos was killed in a duel on December 21, 1643, and was buried at the Pré aux Clercs near Paris.
