Satin 24K Gold Plated Bronze Ancient Coin with Athena's Owl Charm. Replica of an ancient Greek coin. In Greek mythology Athena is the goddess of war, civilization, wisdom, strength, strategy, crafts, justice and skill. In Homeric poetry, Athena's most common epithet translates to bright-eyed or with gleaming eyes, much like an owl. Many scholars argue that Athena is the owl herself - she is wisdom. Our gold plated bronze is 40 micro inches of 24K gold plated over bronze with a fine layer of nickel in between to prevent migration of the two metals. Plated in the USA. Length measurement includes the 5mm soldered jump ring.
