... W. C. Borlase observes that Carew calls St. Levan St. Siluan, and that this form is still retained in the euphonious name of an estate Selena.  Selena was a title under which the Mother of Night, the consort of Cain, the Man in the Moon, was worshipped by the Greeks.  With regard to the Sel of Selena or Silenus it will be seen as we proceed that silly, Seeley, etc., did not imply idiocy, but that silly, as in Scotland where it meant holy, and as in the German selig, primarily meant innocent.  We speak to-day of "silly sheep"; in the Middle Ages Christ was termed the silly Babe, and the county of Suffolk still vaunts itself as Silly Suffolk.  Silene or Selina would thus imply the Innocent or Holy Una: her counterpart Silenus was usually represented as a jovial, genial, and merry patriarch.  Selenus, like Janus, was apparently the Old Father Christmas, and Selena or Cynthia seemingly the maiden Cain, Kayne, St. Kenna, or Jana.
