Jessie Laidlay Weston, From Ritual to Romance — Chapter XIII (1921)
“ Perceval, seeking the Grail Castle, rides all day through a heavy storm, which passes off at night-fall, leaving the weather calm and clear. He rides by moonlight through the forest, till he sees before him a great oak, on the branches of which are lighted candles, ten, fifteen, twenty, or twenty-five. The knight rides quickly towards it, but as he comes near the lights vanish, and he only sees before him a fair little Chapel, with a candle shining through the open door. He enters, and finds on the altar the body of a dead knight, covered with a rich samite, a candle burning at his feet. ”
