Mathematics and Mathematical Astronomy - scanned texts

[furrysocks2]

I happened upon a trove of links to scanned texts such as Principia, Elements, Optics, Conics, etc... from various sources.

Not all are in English though, the majority either in Greek, Latin, Arabic or Sanskrit - most refer to mathematics, some to astronomy.

 

A few select titles:

• Aristarchus of Samos: the Ancient Copernicus 
  A HISTORY OF GREEK ASTRONOMY TO ARISTARCHUS
• A Manual Of Spherical And Practical Astronomy (1891)
• On Ancient Hindu Astronomy and Chronology (1862)
