Appius was the son of Attius Clausus, a wealthy Sabine merchant who emigrated to Rome with a large following in 504 BC, and was admitted to the patriciate under the name of Appius Claudius Sabinus [REF].
The younger Appius is usually regarded as the father of Appius Claudius Crassus, the decemvir, and is so described by both Livy and Dionysius of Halicarnassus.
