Oldest books on Calculus

Question

What are some of the oldest books available on Calculus? I'm curious to see how the old teaching and explanatory styles compare to modern ones.

Answer 1

You mean like Newton's "Method of Fluxions"?

Or perhaps de l'Hospital's "Analyse des infiniment petits"?

Answer 2

Wikipedia lists these important publications in calculus

Edit: Related is this link that has a reference on history of calculus

Answer 3

The wiki article doesn't seem to mention Isaac Barrow's Lectiones Geometricae (1669); which Morris Kline says is "one of the great contributions to the calculus". This should be a good example of how the old thinking differs, as it uses geometrical arguments rather than analytical.
