So Lollio, in “The Changeling,” tells Franciscus that “Luna” made him mad.[12:4] The “parson” who figures, too, among the mad folk in “The Pilgrim,” has to be “tied short” since “the moon’s i’ th’ full.”[12:5]

That the superstition connected with the moon, however, was under high medical patronage is shewn by a reference to the “Anatomie of the Bodie of Man” by one Vicary, chief surgeon at St. Bartholomew’s Hospital (1548-1562). “Also the Brayne” (he writes) “hath this propertie that it moveth and followeth the moving of the moone; for in the waxing of the moone the brayne discendeth downwarde and vanisheth in substance of vertue; for then the Brayne shrinketh together in itselfe and is not so fully obedient to the spirit of feeling, and this is proved in men that be lunaticke or madde . . . that be moste greeved in the beginning of the newe moone and in the latter quarter of the moone. Wherefore when it happeneth that the Brayne is either too drye or too moyst, then can it not werke his kinde; then are the spirits of life melted and resolved away, and then foloweth feebleness of the wittes and of al other members of the bodie, and at the laste death.”

The word “lunatic” itself, it may be noted, quickly passed into common speech, and was used without reference to its original significance. We shall find it constantly recurring throughout this study, but as there is little variety in its use, no further examples need be quoted.

An interesting superstition is connected with

the mandrake plant, round which, from the supposed resemblance of its strangely cleft root to the human figure, many weird notions have gathered. One of these was that when torn from the ground, the plant would utter groans of “sad horror,” which, if heard, caused instant madness, or even death.[14:1] From the numerous references to this superstition in Elizabethan drama may be extracted two,—the first from “Romeo and Juliet” (iv., 3, 47-8), where Juliet speaks of

“shrieks of mandrakes, torn out of the earth

That living mortals, hearing them, run mad”;

the second from a speech of Suffolk’s in “2 Henry VI.” (iii., 2, 310), where the Duke reminds the Queen that curses will not kill

“as doth the mandrake’s groan.”

Other causes to which, rightly or wrongly, insanity is attributed may be grouped together for convenience. In the “Emperor of the East” is an obvious reminiscence of Holy Writ where Flaccilla says of Pulcheria:
