Note 378 — RAPE OF THE LOCK.
Reading edition
"The silver token" alludes to the silver pennies which fairies were said to drop at night into the shoes of maids who kept the house clean and tidy. "The circled green" refers to those rings of grass of a deeper hue than the surrounding pasture, which were formerly believed to be caused by the midnight dances "of airy elves." This was the lore taught by the nurse. The priest infused the legends of "virgins visited by angel-powers."—Croker.
