He took her to a road which skirted the forest. At a crossroads he fashioned a kind of pillory and affixed her to this construction. Over her head he posted a sign: DO WHAT YOU WILL WITH ME and stood back. “Here you stay until three passersby, be they dolts, lickpennies or great earls, have their way with you, and that is the spell I invoke upon you, so that in the future you may choose to be more accommodating to those who accost you beside Tilhilvelly Pond."
