France, jealous of Henry of Lorraine, Duke of Guise, anno 1588, caused him to be murdered in his own chamber. [6009]Louis the Eleventh was so suspicious, he durst not trust his children, every man about him he suspected for a traitor; many strange tricks Comineus telleth of him.  How jealous was our Henry the [6010]Fourth of King Richard the Second, so long as he lived, after he was deposed? and of his own son Henry in his latter days? which the prince well perceiving, came to visit his father in his sickness, in a watchet velvet gown, full of eyelet holes, and with needles sticking in them (as an emblem of jealousy), and so pacified his suspicious father, after some speeches and protestations, which he had used to that purpose.  Perpetual imprisonment, as that of Robert [6011]Duke of Normandy, in the days of Henry the First, forbidding of marriage to some persons, with such like edicts and prohibitions, are ordinary in all states.  In a word ([6012]as he said) three things cause jealousy, a mighty state, a rich treasure, a fair wife; or where there is a cracked title, much tyranny, and exactions.  In our state, as being freed from all these fears and miseries, we may be most secure and happy under the reign of our fortunate prince: 

[6013] “His fortune hath indebted him to none
        But to all his people universally;
        And not to them but for their love alone,
        Which they account as placed worthily. 
        He is so set, he hath no cause to be
        Jealous, or dreadful of disloyalty;
        The pedestal whereon his greatness stands. 
        Is held of all our hearts, and all our hands.”

But I rove, I confess.  These equivocations, jealousies, and many such, which crucify the souls of men, are not here properly meant, or in this distinction of ours included, but that alone which is for beauty, tending to love, and wherein they can brook no co-rival, or endure any participation:  and this jealousy belongs as well to brute beasts, as men.  Some creatures, saith [6014]Vives, swans, doves, cocks, bulls, &c., are jealous as well as men, and as much moved, for fear of communion.

[6015] “Grege pro toto bella juvenci,
        Si con jugio timuere suo,
        Poscunt timidi praelia cervi,
        Et mugitus dant concepti signa furoris.”

       “In Venus’ cause what mighty battles make
        Your raving bulls, and stirs for their herd’s sake: 
        And harts and bucks that are so timorous,
        Will fight and roar, if once they be but jealous.”

In bulls, horses, goats, this is most apparently discerned.  Bulls especially, alium in pascuis non admittit, he will not admit another bull to feed in the same pasture, saith [6016]Oppin:  which Stephanus Bathorius, late king of Poland, used as an impress, with that motto, Regnum non capit duos.  R. T. in his Blazon of Jealousy, telleth a story of a swan about Windsor, that finding a strange cock with his mate, did swim I know not how many miles after to kill him, and when he had so done, came back and killed his hen; a certain truth, he saith, done upon Thames, as many watermen, and neighbour gentlemen, can tell. Fidem suam liberet; for my part, I do believe it may be true; for swans have ever been branded with that epithet of jealousy.
