Messer Amerigo possessed, a mile or so from Trapani, a goodly estate, to which he was wont not seldom to resort with his daughter and other ladies by way of recreation; and on one of these days, while there they tarried with Pietro, whom they had brought with them, suddenly, as will sometimes happen in summer, the sky became overcast with black clouds, insomuch that the lady and her companions, lest the storm should surprise them there, set out on their return to Trapani, making all the haste they might.  But Pietro and the girl being young, and sped perchance by Love no less than by fear of the storm, completely outstripped her mother and the other ladies; and when they were gotten so far ahead as to be well-nigh out of sight of the lady and all the rest, the thunder burst upon them peal upon peal, hard upon which came a fall of hail very thick and close, from which the lady sought shelter in the house of a husbandman.  Pietro and the damsel, finding no more convenient refuge, betook them to an old, and all but ruinous, and now deserted, cottage, which, however, still had a bit of roof left, whereunder they both took their stand in such close quarters, owing to the exiguity of the shelter, that they perforce touched one another.  Which contact was the occasion that they gathered somewhat more courage to disclose their love; and so it was that Pietro began on this wise:—­“Now would to God that this hail might never cease, that so I might stay here for ever!” “And well content were I,” returned the damsel.  And by and by their hands met, not without a tender pressure, and then they fell to embracing and so to kissing one another, while the hail continued.  And not to dwell on every detail, the sky was not clear before they had known the last degree of love’s felicity, and had taken thought how they might secretly enjoy one another in the future.  The cottage being close to the city gate, they hied them thither, as soon as the storm was overpast, and having there awaited the lady, returned home with her.  Nor, using all discretion, did they fail thereafter to meet from time to time in secret, to their no small solace; and the affair went so far that the damsel conceived, whereby they were both not a little disconcerted; insomuch that the damsel employed many artifices to arrest the course of nature, but to no effect.  Wherefore Pietro, being in fear of his life, saw nothing for it but flight, and told her so.  Whereupon:—­“If thou leave me,” quoth she, “I shall certainly kill myself.”  Much as he loved her, Pietro answered:—­“Nay but, my lady, wherefore wouldst thou have me tarry here?  Thy pregnancy will discover our offence:  thou wilt be readily forgiven; but ’twill be my woeful lot to bear the penalty of thy sin and mine.”  “Pietro,” returned the damsel, “too well will they wot of my offence, but be sure that, if thou confess not, none will ever wot of thine.”  Then quoth he:—­“Since thou givest me this promise, I will stay; but mind thou keep it.”
