In these two works Brentel has used information given
to him by Georg Galgemair (see Addenda entry for
Galgemair) to write about both the proportional compass
and the sector, which he called Schregmess. The dates for
Galgemair are uncertain. Following Brental’s practice of
producing full-size broadsheets for sundials, he includes
full-sized plans for both instruments in this work. He also
includes tables giving the positions at which each scale
should be marked. Any instrument maker possessing this
work could easily have reproduced each device.

Brerewood was born and educated in Chester. At the
age of fifteen, he enrolled in Oxford. In 1590, after
graduating with an M.A., he applied for a fellowship
there, but lacking the right connections, he was not given
the position. However, Oxford did recommend him for
the job as the first professor of astronomy at Gresham
College. Ward describes him (Lives of the Professors
of Gresham College, 1740) as very communicative,
and ready to impart what he knew to others, either in
conversation, or by writing, but he never published
anything during his lifetime. A nephew, Robert
