I also suggest that this is possibly a reference to the many works of art entitled The Three Graces dating back to the 16th-century painting by Raphael.
I could well be wrong on both counts, so don't quote me!
Pictured below is Antonio Canova's statue The Three Graces, a Neoclassical sculpture, in marble, of the mythological three charites, daughters of Zeus - identified on some engravings of the statue as, from left to right, Euphrosyne, Aglaea and Thalia - who were said to represent beauty, charm and joy. The Graces presided over banquets and gatherings primarily to entertain and delight the guests of the Gods.
