Lancelot Approaching the Castle of Astolat by: Gustave DorĂ© (Artist) from: Elaine -  1867 This picture illustrates the lines from Tennyson's "Elaine" idyll, later renamed "Lancelot and Elaine": Till as he traced a faintly-shadowed track, That all in loops and links among the dales Ran to the Castle of Astolat, he saw Fired from the west, far on a hill, the towers.
