In poetry from Homer, an oral tradition of the eighth or seventh century BC, onward, Athena's most common epithet is glaukopis, which usually is translated as, bright-eyed or with gleaming eyes. The word is a combination of glaukos, meaning gleaming, silvery, and later, bluish-green or gray) and ops, eye, or sometimes, face. It is interesting to note that glaux ("owl") is from the same root, presumably because of the bird's own distinctive eyes. The bird which sees well in the night is closely associated with the goddess of wisdom: in archaic images, Athena is frequently depicted with an owl named the Glaucus (or "owl of Athena" and later under the Roman Empire, "owl of Minerva") perched on her hand. This pairing evolved in tangent so that even in present day the owl is upheld as a symbol of perspicacity and erudition.
