bonae, obliging; cf. Catul. 89.1. So Tibullus (Tib. 2.4.45) praises the courtesan bona quae nec avara fuit, and Horace's Cinara was bona (Hor. Carm. 4.1.3).
[2] accipiunt: etc. i. e. the price they set is willingly paid.
[2] quod: see Crit. App.
[2] facere: to set; cf. Pl. Pers. 582 “ ‘Indica; fac pretium.’ ‘Tua merx est; tua indicatio est.’”
[3-4] quod … quod: the first quod is probably a conjunction and the second a relative. In promising what she has not performed Aufilena has played the part of an inimica instead of an amica. (With quod as direct object of mentita cf. Prop. 3.17.1 “mentiri noctem” .) Thus vv. 3 and 4 correspond verb for verb,
[3-4] promisti … nec das: she promises but does not perform.
[3-4] mentita … fers: she breaks her appointment but pockets the price.
[3-4] promisti: cf. v. 5 promisse; Catul. 14.14n. misti.
[4] saepe: for she had often received money from him, and hence ought to treat him better now.
[4] facis facinus: cf. Catul. 81.6; Propertius also (l.c.) thought such a breach of faith an awful crime.
[5] ingenuae, honest.
[6] fuit: strictly related in time to v. 5 est: the time to profess virtue was before she made the promise; now honesty requires her to keep it.
[6] data corripere fraudando: etc. to secure the reward by fraud is to exceed the wicked greed of the most abandoned of prostitutes. But none of the emendations yet offered for the corrupt efficit are at all satisfactory.
