SUBSECT.  I.—­Jealousy, its Equivocations, Name, Definition, Extent, several kinds; of Princes, Parents, Friends.  In Beasts, Men:  before marriage, as Co-rivals; or after, as in this place.

Valescus de Taranta cap. de Melanchol. Aelian Montaltus, Felix Platerus, Guianerius, put jealousy for a cause of melancholy, others for a symptom; because melancholy persons amongst these passions and perturbations of the mind, are most obnoxious to it.  But methinks for the latitude it hath, and that prerogative above other ordinary symptoms, it ought to be treated of as a species apart, being of so great and eminent note, so furious a passion, and almost of as great extent as love itself, as [5982]Benedetto Varchi holds, “no love without a mixture of jealousy,” qui non zelat, non amat.  For these causes I will dilate, and treat of it by itself, as a bastard-branch or kind of love-melancholy, which, as heroical love goeth commonly before marriage, doth usually follow, torture, and crucify in like sort, deserves therefore to be rectified alike, requires as much care and industry, in setting out the several causes of it, prognostics and cures.  Which I have more willingly done, that he that is or hath been jealous, may see his error as in a glass; he that is not, may learn to detest, avoid it himself, and dispossess others that are anywise affected with it.

Jealousy is described and defined to be [5983]"a certain suspicion which the lover hath of the party he chiefly loveth, lest he or she should be enamoured of another:”  or any eager desire to enjoy some beauty alone, to have it proper to himself only:  a fear or doubt, lest any foreigner should participate or share with him in his love.  Or (as [5984]Scaliger adds) “a fear of losing her favour whom he so earnestly affects.”  Cardan calls it “a [5985]zeal for love, and a kind of envy lest any man should beguile us.” [5986]Ludovicus Vives defines it in the very same words, or little differing in sense.

There be many other jealousies, but improperly so called all; as that of parents, tutors, guardians over their children, friends whom they love, or such as are left to their wardship or protection.

[5987] “Storax non rediit hac nocte a coena Aeschinus,
        Neque servulorum quispiam qui adversum ierant?”

As the old man in the comedy cried out in a passion, and from a solicitous fear and care he had of his adopted son; [5988]"not of beauty, but lest they should miscarry, do amiss, or any way discredit, disgrace” (as Vives notes) “or endanger themselves and us.” [5989]Aegeus was so solicitous for his son Theseus, (when he went to fight with the Minotaur) of his success, lest he should be foiled, [5990]_Prona est timori semper in pejus fides_.  We are still apt to suspect the worst in such doubtful cases, as many wives in their husband’s absence, fond
