L'aer a se raccolse
Note to Ad Valorem from Unto This Last by John Ruskin

So also in the vision of the women bearing the ephah, before quoted, "the wind was in their wings", not wings "of a stork", as in our version; but "milvi", of a kite, in the Vulgate, or perhaps more accurately still in the Septuagint, "hoopoe", a bird connected typically with the power of riches by many traditions, of which that of its petition for a crest of gold is perhaps the most interesting. The "Birds" of Aristophanes, in which its part is principal, is full of them; note especially the "fortification of the air with baked bricks, like Babylon", 1. 550; and, again, compare the Plutus of Dante, who (to show the influence of riches in destroying the reason) is the only one of the powers of the Inferno who cannot speak intelligibly; and also the cowardliest; he is not merely quelled or restrained, but literally "collapses" at a word; the sudden and helpless operation of mercantile panic being all told in the brief metaphor, ""as the sails, swollen with the wind, fall, when the mast breaks".
