The Frontispeice of the Chronological Automaton or Self-moving EPHEMERIS of ye Celestial Motions, &c Representing ye phaenomena at Noon March 30: 1691 Jnvented and made by SAMUEL WATSON of Coventry Watch-Maker
A Brief Explication of the parts of the first table
aThe center with a little Ball Representing ye globe of ye Earth.
bb &c The orbs of the Respective planets haueing their Epicycles afixt in them
cc &c Shaded lines Representing the Epicycles of ye. Several planets
dd &c The centers of the Epicycles Shewing their Middle Motion ☿ ♀ ☉ ♂ ♃ ♄ Shew what planets the Asterisks to which they are affixt Represent, and ye Asterisks themselv's Shew the apparant place of their respective planets in the Zodiake by a line from the Center to the Asterisk continued to the signe and degree of the Zodiake, as ♄. 28D. of ♏. ♃. 20D. of ♈ ♂ 28D. of ♒. the ☉ neere 20D of. ♈. ♀. 3D of ♓. ☿. 26D. of ♓. and the Moone. 6D. of ♍ when they are direct Swift or Slow Stationary or Retrograde may be Known by obserueing in what part of the Epicycle the planet is or more Mechanically by Seeing the motions of the worke.
The Apogaeons perigaeons and aspects and the Elongations of ♀ and ☿ &c. are suffitiently evident to the intelligent Spectator by observing in what part of their Epicycle they are in and how far distant from each other as ♄ aproaching neere his perigaeon ♃ in his Apogaeon and ♀ drawing towards her Elongation &c.
ee The 12 Celestiall Sign's as computed from the first Star of Aries with the most Remarkable fixt Stars in and about the Zodiak haueing a proper Motion of about one degree in a 100 years &c.
fff &c The Signes of the Zodiak with ye Number of their degrees rekoned from the Vernall Equinox
gg &c The 24 houres of ye Natural Day Serving for ye observation of the horary distance betweene planets of different Longitude, or planets or other Stars &c
hh &c The degrees of terestiall Longitude adapted to the Longitude of London Serving for the Knowledg of ye Southing &c of any of the planets or other Star's to that or any place of Known Longitude &c
ii The Lamina on the Eastern and Western sides of the table with the Characters of the 12 signs of the Eccliptick Fitted for the Latitude of London Shewing the length and Shortness of the Day, And the exact Riseing and Setting of the Signes of the Zodiack with the Stars and planets in them, each Signe then Riseing when it comes ouer against its Correspondent Signe in the Eastern Lamina and setting when it comes to the like on the other side, And the arch aboue or below these Shew (and with the Circle of houres) the Space of tyme which they make aboue or below the Horizon
The Explication of the: 2d: Table
a The center Representing the Earth
kk &c The orbe of the Moon
ll &c The center of her Epicycle Shewing her middle Motion
mm &c The Moon in her Epicycle Shewing her apparent place in ye Zodiak her Apogaeon and perigaeon haueing the Hemisphere next the Sun alwayes Illuminated Serving to Shew her Various phases &c
nn &c.Two Circles one Representing the Eccliptick the other the Orbit of the moon with figures inclosed to shew the degrees of her Latitude
- N☊The North Node
- S☋The South Node
haueing their proper Motion
oo &c The Sun placed here the better to shew his Aspects with ye Moon and Ecclipses;
The Ecclipses, their quantitie, Duration and the parts of the earth which they are Visible in &c. are to be knowne by considering the Latitude of the Moon in her conjunction and opposition with the Sun and the Longitude and Latitude of the Respective places; the Rules for which are here for brevity Sake omited;
pp &c Remarkable Stars in their proper Longitudes which are more Remote from the Eccliptick then those in the former table;
The other parts of this table are Sufficiently Explaind in the Former
The 3 Table
qq &c The innermost Circle by figures from 1. to 28. tells the Cycle of the Sun; The second shews the Dominical Letter; the next shews the months, and the 4 Circles Surrounding it, tells the day of the Month, to be acounted on the inermost the first yeare after Bissextile; and So Succesively to the outermost; which Serues for leape yeare
The 4th Table
rr The innermost Circle shews the Indiction; the middle the golden Number; the outermost the Epact:
The Middle Table
S.M.T.W.T.F.S. are the first Letters of the days of the weeke with their primary planet and in the Circle encompasing them is shewed the houres of the Day computed from 12 to 12:
SS A hole for a Key whereby the whole Machine as depending on one Axis) may be moued for any Number of Days months or yeares either backward or forward presenting to the eye the forementioned phaenomenae happening in that space of tyme, and then being returned to the present yeare Month Day and houre Keeps the tyme for the future, So that upon occasion of any neglect in drawing up the weight which moues the long pendulum (which neede be done but once in Eight Days) the whole is set right;
