Two History of Astronomy Books

Here are a couple of good surveys on the history of astronomy.

A History of Astronomy - A. Pannekoek

Aristarchus of Samos - Sir Thomas Heath

The first is a general history which ranges from ancient to modern times. The second contains a reprint of Aristarchus's work on the diameters and distances of the Sun and the Moon as well as some coverage of prior efforts in Greek astronomy.
