The Romans understood it first. Olive, stone, water, light. Down the road their arch and their mausoleum still stand in the grass, and the olive trees around them are the same trees, more or less, doing the same work they have done since antiquity. Provence has spent two thousand years reawakening the classical world, summoning it back through the plainest means there are. A good olive oil. Bread. A tomato that tastes of the sun that made it. The simplicity only works because everything inside it is the very best. Take the quality away and you are left with lack. Leave it in and you have the most finished thing on the table.
You dress for it accordingly, or you dress for nothing at all, which turns out to be the same instinct. An Hermès Oran, white linen, a woven basket. Light layers, bare where the air allows it, the grasshoppers loud in the grass past noon. There's a point in a Provençal afternoon where you understand that only the simplest and the finest is enough, that anything more would be noise, and that the two words have quietly become the same word.
