His books
Ptolemy's book "The Geography"
Ptolemy was not only an astronomer and mathematician, but an author too! In his lifetime he wrote two separate books, one about geography (shown left) and one about light (shown below).
In his book "The Geography." he drew (what was then) modern maps which sailors used to sail. After Ptolemy was gone, even Christopher Columbus used his book! His other book, "Optics" talks about light and his views on it. They are very good books form what I've heard and I suggest you read them!
