Few have heard of Sicyon, although it is a remarkable and very important ancient city, it was the first city-state in ancient Greece.
And even fewer know that numerous painters and sculptors, now forgotten, lived and created there. https://www.hellenicaworld.com/Greece/Geo/en/Sikyon.html
Almost no one knows about Xenocrates of Sicyon, the first art critic in history.
I quote: "the Greek Xenocrates of Sicyon (3rd century bce) was the first art critic, for he “tried to fix a relationship between his own artistic principles, as categories of artistic judgment, and some concrete artistic personalities.” In other words, Xenocrates—a sculptor of the school of Lysippus—had a philosophy of art, which he brought to bear on the work of particular artists, evaluating them and finding the truth in their art by its measure." https://www.britannica.com/art/art-criticism/Foundations-of-art-criticism-in-antiquity-and-the-Middle-Ages
