Mysia [1]

a surname of the ancient Grecian goddess Demeter, or Ceres, under which she was worshipped near Sparta. The term Mysia is also applied to a festival celebrated by the inhabitants of Pellene in honor of Demeter. This feast lasted for seven days. During the first two days the solemnities were observed by both men and women; on the third day the women alone performed certain mysterious rites throughout the night; and on the last two days the men returned to the festival, and the remainder of the time was passed in raillery and merriment.
