The DUENOS inscription, found by Heinrich Dressel in 1880 on a vase on Quirnal Hill in Rome, is the second earliest known Old Latin text. It is inscribed on the sides of a kernos, in this case a trio of small globular vases adjoined by three clay struts. The kernos is preserved in the Staatliche Museen in Berlin (inventory no. 30894,3).
Old Latin, the precursor of classical Latin, is known from non-book writing, such as stone inscriptions.
