Beija-me as mãos, Amor, devagarinho...
Como se os dois nascessemos irmãos,
Aves cantando, ao sol, no mesmo ninho...<p>Beija-mas bem!... Que fantasia louca
Guardar assim, fechados, nestas mãos,
Os beijos que sonhei pra minha boca!

“Then they invite her to join the dance and approach the holy rites, and make room for her in their ranks and rejoice to be near her. Just as Idalian birds, cleaving the soft clouds and long since gathered in the sky or in their homes, if a strange bird from some distant region has joined them wing to wing, are at first all filled with amaze and fear; then nearer and nearer they fly, and while yet in the air have made him one of them and hover joyfully around with favouring beat of pinions and lead him to their lofty resting-places.”
Dehinc sociare choros castisque accedere sacris
hortantur ceduntque loco et contingere gaudent.
qualiter Idaliae volucres, ubi mollia frangunt
nubila, iam longum caeloque domoque gregatae,
si iunxit pinnas diversoque hospita tractu
venit avis, cunctae primum mirantur et horrent;
mox propius propiusque volant, atque aere in ipso
paulatim fecere suam plausuque secundo
circumeunt hilares et ad alta cubilia ducunt.

Odes, XXIV.
Variant: The bull by nature hath his horns, The horse his hoofs, to daunt their foes; The light-foot hare the hunter scorns; The lion's teeth his strength disclose.The fish, by swimming, 'scapes the weel; The bird, by flight, the fowler's net; With wisdom man is arm'd as steel; Poor women none of these can get. What have they then?—fair Beauty's grace, A two-edged sword, a trusty shield; No force resists a lovely face, Both fire and sword to Beauty yield.
