I am setting out to write a paper, the thesis of which only needs to have the property that it addresses "how was mathematics used in Ancient Greece".
I have begun my own investigation (i.e. excessive googling) to see what I can find, but was curious if any users of this community are already familiar with a source or sources that address interesting aspects $X$ of Ancient Greece with the property that one could argue $X$ was an application of mathematical ways of thinking.
Some first thoughts I had were that if any form of trade and barter was occurring, an argument could be presented that this required some informal notion of solving elementary algebraic equations or arithmetic. Or perhaps if any form of architecture was taking place, an argument could be presented that some informal notions of geometry / spatial relations may have been being applied.
As you can see, there are many stances one could take, and a lot of leeway in how I argue that aspect $X$ of Ancient Greece was 'using mathematics'.
Due to the fact that I do not know much about the history of Ancient Greece, I really don't know what types of things may have been occurring in their culture. Nor do I know where their notion or understanding of mathematics may have been during that time period. Of course, learning and researching both of these is part of the journey of writing this paper - so I am not expecting anyone to answer these for me, I am only hoping or inquiring as to whether anyone can point me towards some niche areas of the internet that address these topics, perhaps someone has something that may not come up in my google searching. If anyone has any sources or insight relating to the use of mathematics in Ancient Greece, that would be most appreciated!
Addendum: I did not even know enough history when I wrote the question to know how ambiguous the term 'Ancient Greece' was. The more specific time period I need to address is Classical Greece, or approximately around 500 - 200 BCE. My instructor is most likely is intending us to address instances before Euclid's formalization.
