I am from ancient Greece

Text

A group of archeologists managed to find some notes of an ancient Greek philosopher. Unfortunately, because his philosophy is so complex, it cannot simply be put into plain mortal words. Thus, he encrypted it using a Polybius square (see attached file)! Can you unravel his wise words? This is what was written on the scroll: 24-13-43-44-51-{-44-15-44-42-11-22-15-14-42-35-33-}

How To Solve

Difficulty: Easy Every pair of numbers corresponds to a greek letter in the polybius square. Translate the letters (https://en.wikipedia.org/wiki/Greek_alphabet) and you get the key in Latin alphabet
