Polyhymnia (Polymnia), "She of Many Hymns," is the muse of Sacred Poetry and is seen with a pensive look upon her face. She has also been called the Muse of geometry, mime, meditation and agriculture. Polyhymnia is often veiled.

The Muses are the Greek goddesses who preside over the arts and sciences and inspire those who excel at these pursuits. Daughters of Zeus, king of the gods, and Mnemosyne ("memory"), they were born at Pieria at the foot of Mount Olympus.
