It is an unfavourable symptom if the rest after this intercourse be uneasy, which plainly indicates that more has been lost than could be repaired by sleep; but if, at the same time, it be productive of relaxation, so as to affect the insensible perspiration, it is a still stronger proof that it has been detrimental to the constitution.[72] ESSAY III. APHRODISIACS, OR, EROTIC STIMULI, AND THEIR OPPOSITES, AS KNOWN TO, AND USED BY, THE ANCIENTS AND MODERNS. When it is considered how strongly the sexual desire is implanted in man, and how much his self-love is interested in preserving or in recovering the power of gratifying it, his endeavours to infuse fresh vigour into his organs when they are temporarily exhausted by over-indulgence, or debilitated by age cannot appear surprising. This remark particularly applied to natives of southern and eastern climes, with whom the erotic ardour makes itself more intensely felt; since it is there that man's imagination, as burning as the sky beneath which he first drew breath, re-awakens desires his organs may have long lost the power of satisfying, and consequently it is there more especially that, notwithstanding the continual disappointment of his hopes, he still pertinaciously persists in searching for means whereby to stimulate his appetite for sexual delights. Accordingly it will be found that in the remotest ages, even the vegetable, animal, and mineral kingdoms have been ransacked for the purpose of discovering remedies capable of strengthening the genital apparatus, and exciting it to action. But however eager men might be in the above enquiry, their helpmates were equally desirous of finding a means whereby they might escape the reproach of barrenness,--a reproach than which none was more dreaded by eastern women. Such means was at last discovered, or supposed to be so, in the mandrake,[73] a plant which thenceforth became, as the following quotation proves, of inestimable value in female eyes. "And Reuben went in the days of wheat harvest, and found mandrakes in the field, and brought them unto his mother, Leah. Then Rachel said to Leah, Give me, I pray thee, of thy son's mandrakes. "And she said unto her, Is it a small matter that thou hast taken my husband? and wouldest thou take away my son's mandrakes also? And Rachel said, Therefore he shall lie with thee to-night for thy son's mandrakes. "And Jacob came out of the field in the evening, and Leah went out to meet him, and said, Thou must come in unto me, for surely I have hired thee with my son's mandrakes. And he lay with her that night. "And God harkened unto Leah, and she conceived and bare Jacob the fifth son."[74] There is only one other passage in the Bible in which this plant is alluded to, and that is in Solomon's song: "The mandrakes give a smell, and at our gates are all manner of pleasant fruits, new and old, which I have laid up for thee, O my beloved."[75]
