The Linen Rolls, Libri Lintei in Latin, were a collection of books written on linen, a technique attested among the Etruscans. These records which, according to one recent theory, originated from notes jotted by officials on their linen clothing, allegedly contained antique lists of annual state officials, and perhaps included records about other matters also. The mysterious Linen Books, stated to have been preserved in the temple of Juno Moneta, need not be dismissed as sheer forgeries fabricated by Gaius Licinius Macer. Yet it is not very likely that they went back to the fourth century BC, as he believed they did; they may not have been more tahn a hundred years old. The Linen Books were also used, with less confidence, by another historian Aelius Tubero, who likewise wrote about myths.
