There is no evidence for any form of writing in Italy before the arrival of Greek colonists in the 8th century bce. The Euboean alphabet brought by settlers at Pithecusae (mod. Ischia) and Cumae was borrowed by the Etruscans, who acted as intermediaries for the spread of writing throughout much of the peninsula. Only in southern regions adjacent to other Greek settlements was the Greek alphabet again borrowed directly, as in Lucania (for writing Oscan see Sabellic languages) and the Sallentine peninsula (with some modifications, for writing Messapian). Greek cities, of course, continued to write in the Greek alphabet throughout antiquity.An alphabet learnt as such (the theoretical alphabet) may contain more letters than are used in practice. So a number of 7th-century Etruscan abecedaria (written-out alphabets) adhere to the Greek model and include letters such as b, d, or o that are not found in texts: abcdevzhθiklmnsopśqrstuṡφχ.
