Another update for the timeline, I think we can all appreciate just how bad it is that the entire human race only had six humans contribute to mathematics over the course of 100 years.
Zenodorus (c. 100?? BCE?)
Posidonius (c. 135-c. 51)
Marcus Terentius Varro (116-27)
Zeno of Sidon (c. 79 BCE)
Geminus of Rhodes (fl. c. 77 BCE)
Cleomedes (c. 40? BCE?)
