ipsi vela regent, ipsis donantibus auras 245
navita tranquillo moderabitur aequore pinum.
nunc pateras libare deis, nunc solvere multo
nectare corda libet. niveos iam pandite coetus,
Naides, et totum violis praetexite fontem;
mella ferant silvae; iam profluat ebrius amnis 250
mutatis in vina vadis; iam sponte per agros
sudent inriguae spirantia balsama venae!
