Lac mihi non aestate novum, non frigore defit;
Canto quae solitus, si quando armenta vocabat,
Amphion Dircaeus in Actaeo Aracintho.
Nec sum adeo informis: nuper me in litore vidi,
Cum placidam ventis staret mare; non ego Daphnim

Judice te metuam, si numquam fallit imago. — ECL., IL. 3. Consumptis hic forte aliis, ut vertere morsus

Exiguam in Cererem penuria adegit edendi
Et violare manu malisque audacibus orbem
Fatalis crusti patulis nec parcere quadris,
“ Heus, etiam mensas consumimus!" inquit Iulus;
Nec plura adludens. Ea vox audita laborum
Prima tulit finem, primamque loquentis ab ore
Eripuit pater, ac stupefactus numine pressit.
