I suggest this is a different method of body time-keeping from the one shown
in the woodcut. Perhaps one of the methods included in Mario Arnaldi's book:

In 1996 I wrote a book on sundials (Orologi solari a Taggia) and I put in
the chapter headed 'natural sundials' (orologi naturali), many types of
those sundial between 'feet sundials', 'Mount sundials', 'flower's sundial'.
The different methods I found making a sundial with hands are essentially
four, plus your.

The dial illustrated is certainly not horizontal. I believe it's a form of
altitude dial.  The surface of the hand is intended to be parallel to the
equator at noon and rotate about the zenith throughout the day.  The user's
back is _always_ to the sun.

As for the translation, please see George McDowell's suggestion, and
possible solution, which is still at:
