Carpe Diem

More Latin in Poul Anderson:

"Carpe diem."
-"The Big Rain,", IV, p. 189.

Tu ne quaesieris, scire nefas, quem mihi, quem tibi
finem di dederint, Leuconoe, nec Babylonios
temptaris numeros. ut melius, quidquid erit, pati.
seu pluris hiemes seu tribuit Iuppiter ultimam,
quae nunc oppositis debilitat pumicibus mare
Tyrrhenum. Sapias, vina liques et spatio brevi
spem longam reseces. dum loquimur, fugerit invida
aetas: carpe diem, quam minimum credula postero.
-copied from here.

Translation:

Ask not ('tis forbidden knowledge), what our destined term of years,
Mine and yours; nor scan the tables of your Babylonish seers.
Better far to bear the future, my Leuconoe, like the past,
Whether Jove has many winters yet to give, or this our last;
This, that makes the Tyrrhene billows spend their strength against the shore.
Strain your wine and prove your wisdom; life is short; should hope be more?
In the moment of our talking, envious time has ebb'd away.
Seize the present; trust tomorrow e'en as little as you may. 
-copied from (same).
