How does it happen, Maecenas, that no one is content with that lot in life which he has chosen, or which chance has thrown in his way, but praises those who follow a different course?
[Lat., Qui fit, Maecenas, ut nemo quam sibi sortem,
Seu ratio dederit, seu fors objecerit, illa
Contentus vivat? laudet diversa sequentes.]
The aim of the poet is to inform or delight, or to combine together, in what he says, both pleasure and applicability to life. In instructing, be brief in what you say in order that your readers may grasp it quickly and retain it faithfully. Superfluous words simply spill out when the mind is already full. Fiction invented in order to please should remain close to reality.
