The posture, garb, and idea of the Statue of Liberty was based off the Colossus of Rhodes (a statue of Helios that is widely considered as one of the Seven Wonders of the Ancient World).  The statue was made around BC 285, and was 107 feet high.

The sketches and illustrations of the statue are really badass.

In many of the depictions, in order to enter the city, you have to go under the spread legs of the statue and look up at a giant perineum.
