By studying the rotation of planets in our solar system, Hypatia (370 AD-415 AD) revolutionized our knowledge of astronomy by creating the Astrolabe (Star Taker) which sailors later used to navigate the seas by locating the North Star (similar to how a compass works) in alignment with the planets to find latitude. Sailors in the south do the same by instead locate the star constellation Crux; Southern Cross. Similar devices are the Spherical Astrolabe, Planispheric Astrolabe, Dioptra Astrolabe, and the Astronomical Clock which display the position of the sun, stars, and planets.
An astrolabe consists of a disk (mater; mother). The mater is held in place by an alidade on a pin.
On top of the mater are plates (tympans).
On top of the plates is a circular rete.
On top rests a horse.
The tympans are to find latitude. They are engraved with a stereographic projection of circles denoting azimurth, altitude and a portion of celestial sphere.
The rim of the mater is to note hours, time, and degree of arc or both.
The rete bears eliptic plane and pointers of brightest stars. It represents the sky as a star chart.
An alidade is attached to the back face.
Some astrolabes have a ruler or label attached as well.
Astrolabes can also be used to read a horoscope. Simple set the degree on east (ascendant), another on the west (descendant), a 3rd on the meridien (mid heaven), then set to time, date of interest (birth, death, etc). The ecliptic degrees are then read. (Stonehenge?)
A Stargate is also a form of an astrolabe. It is a large circular device that when aligned creates a wormhole enabling transportation to cosmic distances and/or other dimensions and time travel.
