Who was the last emperor of Rome?
Romulus Augustulus
Cassiodorus, then a secretary to Theodoric the Great, wrote a letter in 507 to a "Romulus" confirming a pension.[5] Thomas Hodgkin, a translator of Cassiodorus' works, wrote in 1886 that it was "surely possible" the Romulus in the letter was the same person as the last western emperor.[17]  The letter would match the description of Odoacer's coup in the Anonymus Valesianus, and Romulus could have been alive in the early sixth century. But Cassiodorus does not supply any details about his correspondent or the size and nature of his pension, and Jordanes, whose history of the period abridges an earlier work by Cassiodorus, makes no mention of a pension.
