You are to know, then, that in a convent in Lombardy of very great repute for strict and holy living there was, among other ladies that there wore the veil, a young woman of noble family, and extraordinary beauty. Now Isabetta--for such was her name--having speech one day of one of her kinsmen at the grate, became enamoured of a fine young gallant that was with him; who, seeing her to be very fair, and reading her passion in her eyes, was kindled with a like flame for her: which mutual and unsolaced love they bore a great while not without great suffering to both. But at length, both being intent thereon, the gallant discovered a way by which he might with all secrecy visit his nun; and she approving, he paid her not one visit only, but many, to their no small mutual solace. But, while thus they continued their intercourse, it so befell that one night one of the sisters observed him take his leave of Isabetta and depart, albeit neither he nor she was ware that they had thus been discovered. The sister imparted what she had seen to several others. At first they were minded to denounce her to the abbess, one Madonna Usimbalda, who was reputed by the nuns, and indeed by all that knew her, to be a good and holy woman; but on second thoughts they deemed it expedient, that there might be no room for denial, to cause the abbess to take her and the gallant in the act. So they held their peace, and arranged between them to keep her in watch and close espial, that they might catch her unawares. Of which practice Isabetta recking, witting nought, it so befell that one night, when she had her lover to see her, the sisters that were on the watch were soon ware of it, and at what they deemed the nick of time parted into two companies of which one mounted guard at the threshold of Isabetta's cell, while the other hasted to the abbess's chamber, and knocking at the door, roused her, and as soon as they heard her voice, said:--"Up, Madam, without delay: we have discovered that Isabetta has a young man with her in her cell."
