CHAP. V. Of the Sense of Feeling, the deli∣cacy of it in some, and its aboli∣tion in others, also what Vertue hath been found in the touch of some Persons.
WHereas, in the other senses, men are very much excelled, and discernibly surpass'd by the bruit Beasts; yet the judgement of touch, is noted to be more accurate in us, than in most other Creatures. It is true, that this sense is the most abject and inferiour of all other, as perceiving nothing, but what is con∣joyned to it, nor that neither, but by a medium, that is intrinsick; and therefore some will not think it matter of much commendation, that we are so perfect in this, when so comparatively dull in all other senses: Howsoever that be, methinks I cannot but extremely admire the Histories of those persons, wherein this sense hath discover'd it self in its uttermost excellency.
1. Meeting casually with the deserved famous Dr. I. Finch, extraordinary Anatomist to the now Great Duke of Tuscany; and inquiring what might be the chief rarity he had seen in his late return out of Italy into England: He told me it was a man of Maestricht in the Low Countries, who at cer∣tain times, can discern and distinguish colours, by the touch with his finger. I propos'd divers scruples particularly, whether the Doctor had taken care to bind a Napkin or Handkerchief over his Eyes so carefully, as to be sure he could make no use of his sight, though he had but coun∣terfeited the want of it. To which I added divers other questions to satisfie my self, whether there were any likelihood of collusion or other tricks. But I ••ound that the judicious Doctor having gone far out of his way, purposely to satisfie himself, and his learned Prince about this wonder; had been very watchful and circumspect to keep him∣self from being impos'd upon; and that he might not, through any mistake, in point of memory, misinform me: he did me the favour at my re∣quest, to look the notes he had written, for his own, and his Princes information: The sum of which Memorial was this:
That having been in••orm'd at Utrecht, that there liv'd one some miles distant from Maestricht, who could distinguish colours by the touch: When he came to the last named Town, he sent a messenger for him, and having examin'd him, he was told upon enquiry these particulars: That the mans name was John Vermaesen, at that time about thirty three years of age, that when he was but two years old, he had the Small Pox, which rendred him absolutely blind; that at this present he is an Organist, and serves that office in a publick Quire. That the Doctor discoursing with him over night, he affirm'd, he could distinguish colours by the touch, but that he could not do it, unless he were fast∣ing; any quantity of drink taking from him that exquisiteness of Touch, which is requisite to so nice a sensation; that hereupon the Doctor provided against the next Morning seven pieces of Ribbon, of these se∣ven colours; Black, White, Red, Blew, Green, Yellow, and Grey: but as for mingled colours, this Vermaesen would not undertake to discern them, though if offer'd, he would tell that they were mix'd. That to discern the colour of the Ribbon, he places it betwixt the thumb and forefinger; but his most exquisite perception was in his thumb, and much better in his right thumb, than in the left. That after the blind man had four or five times told the Doctor the several colours (though blind∣ed with a Napkin) the Doctor found he was twice mi∣staken, for he call'd the White Black, and the Red Blew; but still he (before his errour) would lay them by in pairs; saying, That though he could easily di∣stinguish them from all others, yet those two pairs were not easily distinguished amongst themselves: Where∣upon the Doctor desir'd to be told by him, what kind of discrimination, he had of colours by his touch: To which he gave a reply: That all the difference was, more or less, asperity: For, says he, Black feels as if you were feeling needles points, or some harsh sand; and Red feels very smooth: That the Doctor having desir'd him to tell him in order the difference of colours to his touch: he did as follows:
Black and White are most asperous, or unequal of all colours, and so like that 'tis hard to distinguish them; but Black is the most rough of the two: Green is the next in asperity; Grey next to Green in aspe∣rity; Yellow is the fifth in degree of asperity: Red and Blew are so like, that they are as hard to distin∣guish as Black and White but Red is somewhat more asperous than Blew: So that Red hath the sixth plaec, and Blew the seventh in asperity.
2. I know there are many will esteem it a fa∣bulous and feigned thing, and I my self should blush to set down the following History in writ∣ing to the World, were it not now well known to all that are in Rome. Iohannes Gambassius Vo∣laterranus from his first youth for twenty years together wrought as a Statuary, and made Statues with great fame and reputation to himself. Soon after he fell stark blind, and for ten years intire lay idle, and never work'd, yet daily revolving in his mind to find out a way, whereby he might recal, and retain that glory he had gain'd in the framing of Statues. He therefore so supply'd the want of his Eyes, with the vigor of his mind, that he attempted a deed unheard of in the Memory of all ages: He undertook to frame of Clay, the Effigies of Cosmo the Great Duke of Hetruria and Tuscany, taking for his Pattern a Marble Statue of the same Cosmo, which he diligently felt and handled. He made it so lively and like, that all men were amaz'd at this new Miracle of Art. Excited therefore with the excellency of the Work, and the acclamations and applause of such as had beheld it, he came to Rome in that ample Theatre, to present a specimen of his Art. It was anno 1636. where first he fram'd the Statue of Pope Vrban the Eight, to such an exact resemblance of him, as was to the admirati∣on of all men, and presented it to Vrban himself. He afterwards made the Statues of Duke Braccia∣nus, of Gualdus and divers others. When he lay sick near St. Onuphrius, and I then his Physician, he often promised me his workmanship in my own, which I utterly refused, that my s••ight service should not be rewarded with so over great a re∣compence: When most men were amaz'd at this
