14238 d´Artagnan           Discovered 1999 Dec. 31 by C. W. Juels at Fountain Hills.
D´Artagnan is the main character of Alexandre Dumas's novel The Three Musketeers. He is a swashbuckling swordsman who joins the three musketeers in many adventures and ultimately earns a commission as a King's Musketeer through his skill, loyalty and devotion. The name was suggested by J. Greer.
