Prepare a research paper on  the mathematician Giovanni Girolamo Saccheri and the essay is about him.

The paper should contain:
1. 1200–2000 words.
2. A description of the geometric work of an individual, group or school and its significance in geometry.
3. Biographical information of at least one individual involved in the work.
4. A reference to at least one primary source (original work), if possible, and a discussion of its
significance. (It is not necessary to read the source, since it is likely to be in a language you may not know. Of course, you may read it and incorporate it into your paper, if possible and appropriate.)
5. A bibliography with at least three references from published sources.
