son of Seleucus, was sick for Stratonice, his mother-in-law, and would not confess his grief, or the cause of his disease, Erasistratus, the physician, found him by his pulse and countenance to be in love with her, [5254]"because that when she came in presence, or was named, his pulse varied, and he blushed besides.”  In this very sort was the love of Callices, the son of Polycles, discovered by Panacaeas the physician, as you may read the story at large in [5255]Aristenaetus.  By the same signs Galen brags that he found out Justa, Boethius the consul’s wife, to dote on Pylades the player, because at his name still she both altered pulse and countenance, as [5256] Polyarchus did at the name of Argenis.  Franciscus Valesius, l. 3. controv. 13. med. contr. denies there is any such pulsus amatorius, or that love may be so discerned; but Avicenna confirms this of Galen out of his experience, lib. 3.  Fen. 1. and Gordonius, cap. 20. [5257]"Their pulse, he saith, is ordinate and swift, if she go by whom he loves,” Langius, epist. 24. lib. 1. med. epist. Neviscanus, lib. 4. numer. 66. syl. nuptialis, Valescus de Taranta, Guianerius, Tract. 15. Valleriola sets down this for a symptom, [5258]"Difference of pulse, neglect of business, want of sleep, often sighs, blushings, when there is any speech of their mistress, are manifest signs.”  But amongst the rest, Josephus Struthis, that Polonian, in the fifth book, cap. 17. of his Doctrine of Pulses, holds that this and all other passions of the mind may be discovered by the pulse. [5259]"And if you will know, saith he, whether the men suspected be such or such, touch their arteries,” &c.  And in his fourth book, fourteenth chapter, he speaks of this particular pulse, [5260] “Love makes an unequal pulse,” &c., he gives instance of a gentlewoman, [5261]a patient of his, whom by this means he found to be much enamoured, and with whom:  he named many persons, but at the last when his name came whom he suspected, [5262]"her pulse began to vary and to beat swifter, and so by often feeling her pulse, he perceived what the matter was.”  Apollonius Argonaut. lib. 4. poetically setting down the meeting of Jason and Medea, makes them both to blush at one another’s sight, and at the first they were not able to speak.

Phaedria trembled at the sight of Thais, others sweat, blow short, Crura tremunt ac poplites,—­are troubled with palpitation of heart upon the like occasion, cor proximum ori, saith [5264]Aristenaetus, their heart is at their mouth, leaps, these burn and freeze, (for love is fire, ice, hot, cold, itch, fever, frenzy, pleurisy, what not) they look pale, red, and commonly blush at their first congress; and sometimes through violent agitation of spirits bleed at nose, or when she is talked of; which very sign [5265]Eustathius makes an argument of Ismene’s affection, that when she met her sweetheart by chance, she changed her countenance to a maiden-blush.  ’Tis a common thing amongst lovers, as [5266]Arnulphus, that merry-conceited bishop, hath well expressed in a facetious epigram of his,
