Penname borrowed from a distant relative, Gioachino Cocchi, the italian 18th century composer better known as "the immortal Comte Saint Germain".
Edgar AllEn Poe helped me solve Saint Germain's riddle along with his own. (See how at Online-literature.com, thread titled Two works by Poe decoded.Announcement!)
Tried-in vain-editing Wikipedia's Al Aaraaf article accordingly, the choice between myth and reality hard to make, I guess, the more so after just realising that Friedrich Melchior Grimm was yet another of Saint Germain's personae .
Let the myth continue and the music play....
Generally: bored.
