Etruscan

Script of the Etruscan civilization of Italy (700–100 BC). It served as the crucial intermediary transmitting the Greek alphabet to the Romans who then spread it worldwide. The Etruscan script can be read, but the Etruscan language itself is not fully decoded — making it famously "readable but not understood." Much of Roman civilization (alphabet, religion, architecture) derived from the Etruscans. ~13,000 Etruscan inscriptions survive today.
