Expressa solis spiculo
nitens imago, quam bene
frontis decus, vim luminum
refers et oris gratiam!

o mira virtus ingeni
novumque monstrum! imaginem
naturae Apelles aemulus
non pulchriorem pingeret.

(Leo XIII, Ars Photographica)

Drawn by the sun’s bright pencil,
How well, O glistening stencil,
You express the brow’s fine grace,
Eyes’ sparkle, and beauty of face.

O marvelous might of mind,
New prodigy! A design
Beyond the contrival
Of Apelles, Nature’s rival.

(tr. Robert Adams)
