What surviving instrument does Mace describe?  What specific
measurements associated with what specific tuning does Mace give us?

Praetorius' 1620 Theatrum Instrumentorum is an encyclopedic work that
shows generic theorbos, not any specific identifiable instrument, but
what the heck:

Praetorius' Lang Romanische Theorba: Chitarron is 14-course double re-
entrant in G, with a length of about 89cm (roughly 3.1 Brunswick Feet
multiplied by 28.536cm per BF) for its six fingerboard strings and an
extension about twice that.  Scaled down for a theorbo in A it would
be about 79 cm.  Would such an instrument be a toy?

Praetorius' Paduanische Theorba is a 16-course instrument, also in G,
about 96cm for the eight fingerboard strings, and 128cm on the
extension, which goes down to a  contra D (i.e. a full octave lower
than the ninth course).  I'd be interested to know how such low notes
at such a short length would work, and how they would balance the
long fingerboard strings.

The lowest fingerboard string on the Paduan theorbo would have been
an E, and thus considerably shorter in relation to its pitch than the
lowest G on the fingerboard of the Roman theorbo; to match the pitch/
length proportion of the Roman theorbo's G, the E would need to be
about 106cm.  Put another way, a theorbo string tuned to A (the sixth
course of a theorbo in A) with the same relation of length to pitch
as a 96cm E string would be 75cm long.  So even the Paduan theorbo
has its toyosity problems.

Has any such instrument survived?  Did anyone else ever mention such
a thing?  Or was it a short-lived variant?  Or was Praetorius'
information faulty?  And is anyone playing such an instrument now?

Praetorius does not mention an absolute pitch level.
