In an apartment of the great temple of Denderah, some fifty years ago, there was discovered upon the granite ceiling a sculptured and painted planisphere, abounding in centaurs, griffins, and dolphins, similar to the grotesque figures on the celestial globe of the moderns.
Then my eyes fell upon the vast planisphere spread upon the table, and I placed my finger on the very spot where the given latitude and longitude crossed.
At this point indicated on the planisphere one of these currents was rolling, the Kuro-Scivo of the Japanese, the Black River, which, leaving the Gulf of Bengal, where it is warmed by the perpendicular rays of a tropical sun, crosses the Straits of Malacca along the coast of Asia, turns into the North Pacific to the Aleutian Islands, carrying with it trunks of camphor-trees and other indigenous productions, and edging the waves of the ocean with the pure indigo of its warm water.
Astrolabes are older, more complex versions of planispheres.
Later that night, they can take part in Superzoom Stargazing where, in partnership with the Mind Museum, they can learn all about heavenly bodies-identifying constellations, naked-eye stargazing with laser pointers, telescopic viewing of celestial bodies, night orienteering, and how to use instruments like planispheres and astrolabs.
These include maps, sketches, plans, drafts, drawings, but also itineraries, derrotas, [2] and travel reports, since cartographic representations can be produced and circulated in other supports than graphic planispheres, such as travel literature (Dym, 2007, pp.
If you've been in this hobby for a number of years, it's easy to think of computer planetarium programs as the digital version of planispheres, those cardboard "star wheels" we used before the computer revolution.
The large manuscript planispheres from the Lisbon padrao and the Seville padron real show the western hemisphere but fill it with large compass roses.
Mr Holmes also correctly observed that the rete (star chart) on the astrolabe is a mirror-image of the sky--for example, Orion's sword appears on the right--and differs from modern planispheres in this respect.
By including only the most prominent deep-sky objects, the ConCards fill the gap between planispheres (such as the Southern Star Wheel) and star atlases.
download an app There are a great number of apps available which make use of the technology inside smartphones, making a great modern alternative to planispheres.
5-million art collection that adorns and inspires, and in some cases has practical functions too--like vibrant canopies that shade from the sun by the main pool (pictured above) and an atrium sculpture that tells in which direction you are sailing (the six-story-high aluminum and stainless-steel creation by Larry Kirkland, inspired by 19th century planispheres, has a compass arrow that is attached to the ship's navigational system).
