Metal instruments modelled on animal horns survive from as early as the 10th century BC, in the form of lurer (a modern name devised by archaeologists). Nearly fifty of these curved bronze horn have been excavated from burial sites, mostly in Scandinavia, since the first was discovered in 1797. Many are in unison pairs, curved in opposite directions. Because their makers left no written histories, their use and manner of playing is unknown. The lur was likely known to the Etruscans, noted as bronze-workers from the 8th century BC, who in turn were credited by the Romans with the invention of their horn and trumpets, including long curved horns in the form of a letter C or G. Depictions of these instruments are found from the 5th century BC onward on Etruscan funerary monuments. The Etruscan name for them is unknown, but the Romans called them buccina and cornu. The latter name is the Latin word for "horn", and the source of the name of the musical instrument in many Romance languages: French cor, Italian corno, Provençal corn
