SYNOPSIS OF THE COMPLETE MECHANICAL WORKS OF THE FIRST CLOCK

[Translated from the section entitled "Synopsis Totius Operis
Mechanici" in Francesco Borghesi's first book _Novissima Ac
Perpetua Astronomica Ephemeris Authomatica
Theorico-Practica..._.]

I

Of three movable indices, the farthest from the center of the dial is
fitted with an index on either side and marked with four segments of a
circle. Immediately below are five numbers, divided into the days of
setting the measure of the mean-synodic age of the moon, and into signs,
degrees of the signs, and of the distance of the moon from the sun.
These, in each revolution, revolve once around the solar disk
superimposed on the mean synodic-lunar disk, and also around the lunar
disk. The upper indices, meanwhile, in the two external greatest orbits,
measure the time continuously, in the accustomed manner of the
Germans--the middle index measuring by hours and the uppermost by the
first minutes [of hours].

II

Inside these three circles, perpendicular above their center, is a small
index of the seconds of minutes. At each first minute of time, being the
fastest of all, it describes the smallest orbit. Next to this are two
other slightly larger circles divided into 30 degrees, one [rotating?]
from the right, the other from the left. These two indices are arranged
in such a fashion that the one rotating from the observer's left
completes its period 12 times during one, mean, solar-astronomical year.
The one [rotating] from the right likewise completes its cycle 12 times
during the period of one mean-synodic moon. In between these, there is
placed another small sphere, divided into 40 arbitrary parts, whose dial
does not move automatically, but is moved by hand for speeding up or
sl
