[14] The abbreviation in the inscription "pLan" is difficult to
interpret. According to Father F. X. Winters, S.J., it may represent
"sit planetis" or "sit planetarum." The use of an abbreviation was
necessary to prevent the addition of another letter I or M, which would
have disturbed the formation of the chronogram desired. Literally, "sit
planetis" means "May he be eternal ruler _by_ [or _through_] favor of
the planets," while "sit planetarum" is to be translated "May he be
eternal ruler _of_ the planets." Father Winters considered both versions
somewhat overexaggerated and proposed that the best translation might be
"Long Live Francis I, Emperor."
[15] The word "Tempe" refers to the Vale of Tempe, in Thessaly, through
which the Peneus River flows. It is between Mounts Olympus and Ossa, and
is situated between the town of Larissa and the sea. In mythology, it is
told that these mounts were originally joined and Hercules separated
them to allow the river to pass between them. The word "Tempe" is also
used to mean any pleasant place. Thus, the inscription "Tempe
indesinenter clausa, Scaturigo signata" is literally translated "Tempe
always closed, A fount of water sealed up" or, freely translated, as "A
garden enclosed, a fountain sealed up."
[16] "Phoebi" or Phoebus, called Apollo, the sun god; Phoebes or Diana,
the moon goddess, sister of Apollo.

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..._.]

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].
