In an unhappy moment Rodaja ate the quince, but had scarcely done so when he began to tremble from head to foot as if struck by apoplexy, remaining many hours before he could be brought to himself.  At the end of that time he partially recovered, but appeared to have become almost an idiot.  He complained, with a stammering tongue and feeble voice, that a quince which he had eaten had poisoned him, and also found means to intimate by whom it had been given, when justice at once began to move in quest of the criminal; but she, perceiving the failure of her attempt, took care to hide herself, and never appeared again.

Six months did Thomas remain confined to his bed; and during that time he not only became reduced to a skeleton, but seemed also to have lost the use of his faculties.  Every remedy that could be thought of was tried in his behalf; but although the physicians succeeded in curing the physical malady, they could not remove that of the mind; so that when he was at last pronounced cured, he was still afflicted with the strangest madness that was ever heard of among the many kinds by which humanity has been assailed.  The unhappy man imagined that he was entirely made of glass; and, possessed with this idea, when any one approached him he would utter the most terrible outcries, begging and beseeching them not to come near him, or they would assuredly break him to pieces, as he was not like other men but entirely of glass from head to foot.

In the hope of rousing him from this strange hallucination, many persons, without regard to his prayers and cries, threw themselves upon him and embraced him, bidding him observe that he was not broken for all that.  But all they gained by this was to see the poor creature sink to the earth, uttering lamentable moans, and instantly fall into a fainting fit, from which he could not be recovered for several hours; nay, when he did recover, it was but to renew his complaints, from which he never desisted but to implore that such a misfortune might not be suffered to happen again.

He exhorted every one to speak to him from a great distance; declaring that on this condition they might ask him what they pleased, and that he could reply with all the more effect, now he was a man of glass and not of flesh and bones, since glass, being a substance of more delicate subtlety, permits the soul to act with more promptitude and efficacy than it can be expected to do in the heavier body formed of mere earth.

Certain persons then desiring to ascertain if what he had said were true, asked him many questions of great difficulty respecting various circumstances; to all these he replied with the utmost acuteness, insomuch that his answers awakened astonishment in the most learned professors of medicine and philosophy whom that university could boast.  And well they might be amazed at seeing a man who was subject to so strange an hallucination as that of believing himself to be made of glass, still retain such extraordinary judgment on other points as to be capable of answering difficult questions with the marvellous propriety and truth which distinguished the replies of Rodaja.
