M' Lady's Spots

Supplementing my entomological reading of "Ephelia" is contemporary usage of "spots" to refer to stylish cosmetic patches (beauty marks) worn by courtesans and (to conceal venereal blemishes) by prostitutes. When Queen Catherine of Braganza's mother died, "the Court wore the deepest mourning; the ladies were directed to wear their hair plain and to appear without spots on their faces, the disfiguring fashion of patching having just been introduced. Lady Castlemaine was considered to appear to great disadvantage without her patches."(Strickland, "Catherine of Braganza," Lives X:261). If Mary Villiers had been in the habit of wearing 'spots,' her choice in pseudonym could be easily explained; but, to date, I have not found anything in contemporary sources to support this. And if she were naturally spotted or freckled, she would not have been praised as a great English beauty.
