Go Now and Read!

Jessica Palmer at Bioephemera has a wonderful post on Medieval Astrolabs

Quadrant, January 3 1775, "M. H.", Danvers, Massachusetts, inked paper over wood

I've had the opportunity to see and photograph some of the Octants, Quadrants, Astrolabes and Sextants at the Peabody Essex Museum in Salem MA. (click here for Flickr photo set then scroll about halfway down the page) These are truly marvelous and elegant bits of history.

Go and read Ms. Palmer's post. For one thing, her images are clearer than mine.

Planespheric Astrolabe, mid 17th century, attributed to Maquim Muhammed (active 1644), possibly Lahore, Pajistan, brass
