By Sir Lodovico Gandini.

P ainting, which every man so greatly delights in,
Is called mute poetry: This refers to a famous ancient aphorism attributed to Simonides of Ceos: "painting is silent poetry and poetry is speaking painting."
But let it also be called
Poetry that speaks;
Since within your style all of it is discerned
So well adorned with eternal words.

S peaking painting
We call Poetry.
Eloquent Poetry
We say is Painting:
Painting therefore and Poetry are equals.
But how much more are they equal,
If to this To poetry. light was given through his pages by
Homer, who was without lights; original: "senza luci". In Italian verse, "lights" is a standard metaphor for eyes. Homer, the father of Greek epic poetry, was famously blind.
And you, deprived of lights, Lomazzo lost his sight in 1571 at age 33; this "deprivation" is a recurring theme in the book's introductory poems to emphasize his inner vision.
Give light to this To painting. with your pen?

P ainters once had lights; They had physical eyesight.
But they did not paint with light: Here, "light" refers to the intellectual and theoretical clarity that Lomazzo’s writing provides to the practice of art.
Now they shall not only have lights,
But they shall paint with light.
Who offers them this light?
Your shining work, though you are deprived of lights.
Most high Painter, overflowing with light.

Bernardini Likely referring to the printer or a member of the production circle.
