An armoured knight stands between two fountains, one flowing red and one white — the twin streams whose union alchemists took as the heart of the work, sol and luna, the red and the white made one. Splendor Solis stages the meeting as a courtly tableau, the figure poised in a manicured Renaissance garden about 1582. Red and white run through the whole tradition: the two tinctures, the two lights, the marriage the Great Work was always driving toward. The plate hands you the doctrine as a single legible picture — two waters, one ground — and wraps it, as ever, in a border of painted flowers.

Before a size goes on sale, the file is measured against it: pixels per inch at that size, how much of the picture a crop would lose, tone and sharpness. A size that fails is not offered, so there is nothing to choose wrong.
