It came to passe, that _Arriguccio_, either by rumour, or some other more sensible apprehension, had received such intelligence concerning his Wife _Simonida_, as he grew into extraordinarie jealousie of her, refraining travaile abroad, as formerly he was wont to doe, and ceassing from his verie ordinary affayres, addicting all his care and endeavour, onely to be watchfull of his Wife; so that he never durst sleepe, untill she were by him in the bed, which was no meane molestation to her, being thus curbd from her familiar meetings with _Roberto_. Neverthelesse, having a long while consulted with her wittes, to find some apte meanes for conversing with him, being thereto also very earnestlie still solicited by him; you shall heare what course she undertooke.
Her Chamber being on the streete side, and somewhat juttying over it, she observed the disposition of her Husband, that every night it was long before he fell asleepe: but beeing once falne into it, no noyse whatsoever, could easily wake him. This his solemne and sound sleeping, emboldned her so farre, as to meete with _Roberto_ at the streete doore, which (while her Husband slept) softly she would open to him, and there in private converse with him.
But, because shee would know the certaine houre of his comming, without the least suspition of any: she hung a thred forth of her Chamber Window, descending downe, within the compasse of _Robertoes_ reach in the street, and the other end thereof, guided from the Window to the bed, being conveyed under the cloathes, and shee being in bed, she fastned it about her left great Toe, wherewith _Roberto_ was sufficiently acquainted, and thus enstructed withall; that at his comming, he should plucke the thred, & if her husband was in his dead sleep, she would let go the thred, and come downe to him: but if he slept not, she would hold it strongly, and then his tarrying would prove but in vaine; there could be no meeting that night.
This devise was highly pleasing both to _Roberto_ and _Simonida_, being the intelligencer of their often meeting, and many times also advising the contrary. But in the end, as the quaintest cunning may faile at one time or another; so it fortuned one night, that _Simonida_ being in a sound sleepe, and _Arriguccio_ waking, because his drowsie houre was not as yet come: as he extended forth his legge in the bed, he found the thred, which feeling in his hand, and perceiving it was tyed to his wives great toe; it prooved apt tinder to kindle further Jealousie, and now hee suspected some treachery indeede, and so much the rather because the thred guided (under the cloathes) from the bed to the window, and there hanging downe into the streete, as a warning to some further businesse.
