About
the Antikythera Mechanism & Graphic Astrology/Astronomy Ephemeris
The Graphic Ephemeris is a twenty-first century digital animated planet
and star chart, presenting the night sky in analog timepiece format,
akin to the Antikythera Mechanism.
The Antikythera Mechanism was an ancient astronomical clock or astrarium.
The ruins of this orrery device were recovered from a two thousand
year old sunken ship wreck in the Mediterranean Sea near the island
of Antikythera.
The relic is presumed to have been constructed by the early Greeks
who, unlike people of the modern era, did not distinguish between
astronomy and astrology. Both scientific observation and esoteric
knowledge are wound-up together in the Antikythera Mechanism.
A complex arrangement of clockwork-like gears controlled the mechanism,
as current day reconstructions of the device demonstrate. On the other
hand, the Graphic Astrology Ephemeris utilizes a database of coordinates,
driven by equations, to achieve a similar looking planetary cyclic
rotation.

about both,
continued...
In the ancient world, the Sun, Moon, Mercury, Venus, Mars, Jupiter
and Saturn were known and, as in a planetarium, their positions are
acutely calculated in the Antikythera astrolabe type artifact. The
Ephemeris adds in the planets Uranus, Neptune and Pluto. These planets
were not incorporated in the Antikythera Mechanism because they are
normally too dim to be seen with the naked eye. Uranus however, is
visible at it's close approach under very clear skies.
Latitude and longitude positions of the planets, along the ecliptic,
are displayed in the Star
version of the Graphic Ephemeris. The
Antikythera Mechanism does not display planetary latitudes in relation
to the zodiac, probably not because this info was unknown to the ancient
Greeks, but due instead to it's difficulty to "gear" it into the machine.
Both celestial computers, like tellurions and torquetums, are anaphoric
star disks, animated views of our solar system's complexity and beauty.
