Astronomy in a parallel universe

[Lionel Mandrake]

5. A note on Kepler's book describing the first two laws

Originally published in Latin, Kepler's Astronomia Nova (1609) has been translated by Max Caspar into German:

and by William H. Donahue into English:

Both of those translations are apparently out of print. The English translation has always been outrageously expensive, but you might find it in a library. Those who can read German can find used copies of Max Caspar's old translation at a reasonable price. But the best deal for most readers would be William H. Donahue's Selections from Kepler's Astronomia Nova (Science Classics Module for Humanities Studies), used copies of which are reasonably priced:

Although I generally prefer complete works to selections, in this case the price differential is overwhelming.
