The passion flower, its clockwork of filaments impossibly precise, set against the stormy, atmospheric backdrop that made *The Temple of Flora* unlike anything before it. Thornton nearly ruined himself producing these plates; the result is one of the most beautiful and dramatic flower books ever printed. He died poor. The book outlived him by two centuries.

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.
