Giovanni Boccaccio - Decameron (Day the Eighty Eighth) lyrics
Here Beginneth the Ninth Day of the Decameron Wherein Under the Governance of Emilia Each Discourseth According As It Pleaseth Him and of That Which Is Most to His Liking
The light, from whose resplendence the night fleeth, had already changed all the eighth heaven from azure to watchet-colour and the flowerets began to lift their heads along the meads, when Emilia, uprising, let call the ladies her comrades and on like wise the young men, who, being come, fared forth, ensuing the slow steps of the queen, and betook themselves to a coppice but little distant from the palace. Therein entering, they saw the animals, wild goats and deer and others, as if assured of security from the hunters by reason of the prevailing pestilence, stand awaiting them no otherwise than as they were grown without fear or tame, and diverted themselves awhile with them, drawing near, now to this one and now to that, as if they would fain lay hands on them, and making them run and skip.

They were all garlanded with oak leaves, with their hands full of flowers and sweet-scented herbs, and whoso encountered them had said no otherwhat than "Or these shall not be overcome of death or it will slay them merry."

 D'azzurrino in color cilestro. This is one of the many passages in which Boccaccio has imitated Dante (cf. Purgatorio, c. xxvi. II. 4-6, "... il sole.... Che già, raggiando, tutto l'occidente Mutava in bianco aspetto di cilestro,") and also one of the innumerable instances in which former translators (who all agree in making the advent of the light change the colour of the sky from azure to a darker colour, instead of, as Boccaccio intended, to watchet, i.e. a paler or greyish blue,) have misrendered the text, for sheer ignorance of the author's meaning.
