Democritus has regarded the nyctegreton2066 as one of the most singular of plants. According to that author, it is of a dark red colour, has leaves like those of a thorn, and creeps upon the ground. He says that it grows in Gedrosia2067 more particularly, and that it is taken up by the roots immediately after the vernal equinox, and dried in the moonlight for thirty days; after which preparation it emits light by night. He states also, that the Magi and the kings of Parthia employ this plant in their ceremonies when they make a vow to perform an undertaking; that another name given to it is “chenomyche,”2068 from the circumstance that, at the very sight of it, geese will manifest the greatest alarm; and that by some persons, again, it is known as the “nyctalops,”2069 from the light which it emits at a considerable distance by night.
