I am more famed in Heaven for my works than I could well conceive. In my brain are studies & chambers filled with books & pictures of old, which I wrote and painted in ages of Eternity before my mortal life; and whose works are the delight & study of Archangels. Why, then, should I be anxious about the riches or fame of mortality?
