Metrodorus of Lampsacus was a Greek philosopher of the Epicurean school. Although one of the four major proponents of Epicureanism, only fragments of his works remain.

The philosophy of Metrodorus appears to have been of a more sensual kind than that of Epicurus. Perfect happiness, according to Cicero's account, he made to consist in having a well-constituted body, and knowing that it would always remain so. He found fault with his brother for not admitting that the belly was the test and measure of every thing that pertained to a happy life. According to Seneca, Epicurus placed Metrodorus among those who acquire assistance in working their way towards truth.

This bust has a very unclear origin and is could have been 'perfected' from several other original representations of Metrodorus. The piece itself was cast by an 'E. Gastecloux' in 1793 from a mould at The Academy of Fine Arts in Saint Petersburg.
