Pontifex University Blog: Chartres Cathedral and Philosophers
By Carrie Gress, Ph.D.
I’ve just started doing some research on Chartres Cathedral and ran across this quotation from 11th century Thierry of Chartres. In his work, the Heptateuchon, Thierry says, “Philosophy has two principal instruments, the mind and its expression. The mind is enlightened by the Quadrivium (arithmetic, geometry, astronomy and music), its expression, elegant, reasonable, ornate is provide by the Trivium (grammar, rhetoric and dialectic).” These seven liberal arts and the artists who most exemplify them are featured on the Royal Portal of Chartres Cathedral.
