As when, from mountain tops, the dusky clouds
Ascending, &c. — (ii. 488.)

Q UALES airii montis de vertice nubes
Cum surgunt, et jam Boreae tumida ora quierunt,
Caelum hilares abdit spissa caligine vultus,
Nimbosumque nives aut imbres cogitat aether:
Tum si jucundo tandem sol prodeat ore,
Et croceo montes et pascua lumine tingat,
Gaudent omnia, aves mulcent concentibus agros,
Balatuque ovium colles vallesque resultant.
