Adding to the above, I've written the image with the greek text on the above linked page into unicode: Μὴ μου τοὺς κύκλους τάραττε
The difference between that and what's already listed is that I added to accent grave marks over the first Eta and the Upsilon in the third word. I don't know which one is more correct, eventually I'll check with an expert. The difference may be due to something different between modern and ancient greek.
Do not disturb my cycles 
The last words of Archimedes "Μὴ μου τοὺς κύκλους τάραττε" can also be translated as "Do not disturb my thought process" metaphorically, since "κύκλος" can be a synonym for "λογισμός", which means "thought". 188.8.131.52
