The illustration is from Peacham's
Rosicrucian 1612 emblem book "Minerva Britanna, or a
garden of heroical devices, furnished and adorned with
emblems and Impresas of sundry devices, newly devised,
moralized and published." On the frontispiece is an oval
wreathed with laurel, and a Latin motto which translated as:
"One lives in one's genius, other things depart in death,"
Within the oval is the proscenium of a theater, the curtain
supposed to conceal the figure of a man whose forearm only
appears, the hand holding a pen which has just written
"Mente Videbor": "By the mind shall I be seen."
That clouds thy worth in such obscurite"
On page 34 is a dedication to Bacon : "To the most judicious and learned Sir Francis Bacon, Knight."
