Some 2,000 years ago, during military parades in northern Europe, cavalry officers in the service of Rome wore bronze masks that were intended to induce awe in the rabble. In 1970, the mask pictured here made its way into the collection of Rupert Wace (www.rupertwace.co.uk), a London antiquities dealer, who this month will bring it and 78 other pieces to the 53rd annual Winter Antiques Show (www.winterantiquesshow.com) at the Seventh Regiment Armory in New York City. Wace says that he expects the mask to fetch about $280,000. An Egyptian sculpture in his collection, a limestone relief of a male head dating to about 660 B.C., could command a similar price. The antiques show, which will take place from January 19 through 28, will include 74 exhibitors displaying such items as medieval manuscripts, Chinese porcelain, Russian artworks, jewelry, carpets, textiles, and arms and armor.
