Rari quippe boni, numerus vix est totidem quot
Thebarum portoe, vel divitis ostia Nili. JUV. Sat. xiii. 26.
Good men are scarce, the just are thinly sown:
They thrive but ill, nor can they last when grown.
And should we count them, and our store compile,
Yet Thebes more gates could shew, more mouths the Nile.
