Fillitas (or possibly Fillytas; see below) of [[Ponylon]] was an early pony philosopher and mathemetician, a near-contemporary of [[Aristrottle]]. She flourished some time around [[1st Millennium BE|600-500 BE]]. She is claimed by classical historians of all three [[Little Pony|Pony tribes]] but was probably an Earth Pony.
 
Fillitas is said to have reformed the system of pony [[Numeracy|numeracy]], creating a base-thirty positional number system, allegedly by multiplying the first four prime numbers. 

A rhetorician Fillytas is also mentioned an ancient documents. She supposedly dropped dead of exhaustion while attempting to enumerate all the grammatical and logical errors in a political speech. Classical historians believed Fillytas the Rhetorician to be the same person as Fillitas the Mathemetician, but it is not known with absolute certainty.
