and chose a torch, representing progress, for the figure to hold. Crawford's statue was designed in the early 1850s. It was originally to be crowned with a pileus, the cap given to emancipated slaves in ancient Rome. Secretary of War Jefferson Davis, a Southerner who would later serve as President of the Confederate States of America, was concerned that the pileus would be taken as an abolitionist symbol. He ordered that it be changed to a helmet. Delacroix's figure wears a pileus, and Bartholdi at first considered placing one on his figure as well. Instead, he used a radiate diadem, or crown, to top its head. In so doing, he avoided a reference to Marianne, who invariably wears a pileus. The seven rays form a halo or aureole. They evoke the sun, the seven seas, and the seven continents, and represent another means, besides the torch, whereby Liberty enlightens the world. Bartholdi's early models were all similar in concept: a female figure in neoclassical style representing liberty, wearing a stola and pella (gown and cloak, common in depictions of Roman goddesses) and holding a torch aloft. According to popular accounts, the face was modeled after that of Charlotte Beysser Bartholdi, the sculptor's mother, but Regis Huber, the curator of the Bartholdi Museum is on record as saying that this, as well as other similar speculations, have no basis in fact. He designed the figure with a strong, uncomplicated silhouette, which would be set off well by its dramatic harbor placement and allow passengers on vessels entering New York Bay to experience a changing perspective on the statue as they proceeded toward Manhattan. He gave it bold classical contours and applied simplified modeling, reflecting the huge scale of the project and its solemn purpose. Bartholdi wrote of his technique: Bartholdi made alterations in the design as the project evolved. Bartholdi considered having Liberty hold a broken chain, but decided this would be too divisive in the days after the Civil War. The erected statue does stride over a broken chain, half-hidden by her robes and difficult to see from the ground. Bartholdi was initially uncertain of what to place in Liberty's left hand; he settled on a tabula ansata, used to evoke the concept of law. Though Bartholdi greatly admired the United States Constitution, he chose to inscribe JULY IV MDCCLXXVI on the tablet, thus associating the date of the country's
