Contact with [menstrual blood] turns new wine sour, crops touched by it become barren, grafts die, seed in gardens are dried up, the fruit of trees fall off, the edge of steel and the gleam of ivory are dulled, hives of bees die, even bronze and iron are at once seized by rust, and a horrible smell fills the air; to taste it drives dogs mad and infects their bites with an incurable poison.
Pliny the ElderThere is an herb named in Latine Convolvulus (i.e. with wind), growing among shrubs and bushes, with carrieth a flower not unlike to this Lilly, save that it yeeldeth no smell nor hath those chives within; for whitenesse they resemble one another very much, as if Nature in making this floure were a learning and trying her skill how to frame the Lilly indeed.
