Long since the vow was made, and now is fulfilled." (_Ciris_, 42-7.)[1]

The story, beginning at line 101, was familiar. Minos, King of Crete, had
laid siege to Megara, whose king, Nisus, had been promised invincibility
by the oracles so long as his crimson lock remained untouched. Scylla,
the daughter of Nisus, however, was driven by Juno to fall in love with
Minos, her father's enemy; and, to win his love, she yields to the
temptation of betraying her father to Minos. The picture of the girl when
she had decided to cut the charmed lock of hair, groping her way in the
dark, tiptoe, faltering, rushing, terrified at the fluttering of her own
heart, is an interesting attempt at intensive art: 209-219:

auribus erectis nocturna silentia temptat
et pressis tenuem singultibus aera captat.
tum suspensa levans digitis vestigia primis
egreditur ferroque manus armata bidenti
evolat: at demptae subita in formidine vires
caeruleas sua furta prius testantur ad umbras.
nam qua se ad patrium tendebat semita limen,
vestibulo in thalami paulum remoratur et alti
suspicit ad gelidi nictantia sidera mundi
non accepta piis promittens munera divis.
