 This was granted near the close of 46 BC, though Marcellus did not start out for Rome until the middle of 45 BC.En route near Athens he was murdered by one of his own attendants, P. Magius Chilo, an event that some attributed to Caesar, but Cicero suggested was almost certainly caused by a dispute between Magius and Marcellus.Marcellus was the son of another Marcus Claudius Marcellus, "aedile curulis" in 91 BC; the brother of Gaius Claudius Marcellus Maior, consul in 49 BC and the cousin of Gaius Claudius Marcellus Minor, consul in 50 BC.
