"the Doric column on her head"
Doric columns were another architectural invention of the Ancient Greeks. They were the plainest of the three styles making up the Classical Order, the other two being Ionic and Corinthian. They can be seen on the Parthenon at the Acropolis in Athens. As with so many features of Classical civilisations, they were highly sophisticated; part of their design allowed rainwater to be drained away from above. Made of marble, they were used to support the sides of temples and create visual harmony.
