Luca Giordano·1651
Historical Context
Euclid in the Gemaldegalerie Berlin depicts the ancient Greek mathematician, part of a tradition of portraying famous scholars and thinkers that was popular in seventeenth-century painting.

Look Closer
- ◆Notice the geometric instruments that identify Euclid — compasses, ruler, or diagram — depicted alongside the ancient mathematician as attributes of his discipline.
- ◆Look at the aged face illuminated by Ribera-style directed light: the weathered philosopher whose face carries both age and intellectual intensity follows the tradition of ragged sages that Ribera established in Naples.

- ◆Observe that this 1651 Gemäldegalerie Berlin work places Giordano's Euclid in one of the world's great paintings collections alongside works by Vermeer, Caravaggio, and Rembrandt — the context revealing how highly these philosopher portraits were valued.
