Thus far, Ithaca has discovered that the Athenian Decrees were written around 421 B.C.E. — these are the foundational documents of the world’s first democracy. Past conventional thinking had put their date closer to 446 B.C.E. Even the shift of just 15 years helps scholars re-contextualize these documents — now we know they were written at the same time as Athens prepared to go to war with Sparta, another Ancient Greek state that was governed as a military autocracy.
