The grey day seems to suit this image of Stonewall Jackson over his grave in the cemetery named in his memory -- click photo for more detail. (He's facing south, of course.)
The 1891 sculpture was done by Edward Virginius Valentine, a Richmond artist known also for his likenesses of Thomas Jefferson (in Richmond), Robert E. Lee (standing, in the Capitol in Washington; and recumbent, in the Lee Chapel), and Jefferson Davis (on Monument Ave. in Richmond).
Valentine's studio has been preserved and is open to the public. It seems to have been an attraction even during the artist's lifetime -- a guest book there contains the names of both Woodrow Wilson and Oscar Wilde.
