No other sky was quite what this one was. Any time of year, any season: whether a late autumn’s cold dawn or midday in drowsy summer among the cicadas. Or when the knife of wind—the mistral—ripped down the Rhone valley (the way soldiers had so often come), making each olive or cypress tree, magpie, vineyard, lavender bush, aqueduct in the distance stand against the wind-scoured sky as if it were the first, the perfect, example in the world of what it was.

Aix-en-Provence, the city, lay in a valley bowl west of the villa. No trees in that direction to block the view from this high. The city, more than two thousand years old, founded by Romans conquering here—surveying and mapping, levelling and draining, laying down pipes for thermal springs, and their dead-straight roads—could be seen on spring mornings like this one crisply defined, almost supernaturally clear. Medieval houses and modern ones. A block of new apartment buildings on a northern slope, and—tucked into the old quarter—the bell tower of the cathedral rising.

They would all be going there this morning. A little later than this, but not too much so (two alarm clocks had gone off in the house by now, the one woman was already showering). You didn’t want to linger of a morning, not with what they were here to do.

Photographers knew about this light.

They would try to use it, to draw upon it as someone with a thirst might have drawn from an ancient well—then again at twilight to see how doorways and windows showed and shadowed differently when the light came from the west, or the sky was blood-red with sunset underlighting clouds, another kind of offering.

Gifts of different nuance, morning and evening here (noon was too bright, shadowless, for the camera’s eye). Gifts not always deserved by those dwelling—or arriving—in a too-beautiful part of the world, where so much blood had been shed and so many bodies burned or buried, or left unburied, through violent centuries.
