Quintus Claudius Quadrigarius, Roman annalist, living probably in the 1st century BC, wrote a history, in at least twenty-three books, which began with the conquest of Rome by the Gauls and went on to the death of Sulla or perhaps later.
Livy freely used Quadrigarius in part of his work (from the sixth book onwards). A big fragment is preserved in Aulus Gellius (ix. 13), giving an account of the famous single combat between T. Manlius Torquatus and a Gaul. His language was antiquated and his style dry, but his work was considered important.
