WASHINGTON.- "Miriam," a head of a woman carved in alabaster from the 1st century BCE, appears in a gallery of artifacts discovered by American adventurer Wendell Phillips in southern Arabia, now Yemen, during an exhibition of his discoveries at the Smithsonian's Freer and Sackler Galleries of Art in Washington, DC, October 2, 2014. Wendell Phillips was still in his mid-20s when he spearheaded his own expedition into the desert of what is today Yemen, searching its sifting sands for relics of a civilization that thrived 2,500 years before. Several of his discoveries have just gone on display at the Smithsonian's Freer-Sackler museum of Asian art in Washington, in a show that honors his groundbreaking archeological work in southern Arabia.
