Roman Empire from this point only required a single emperor, ruling from Constantinople. Though Zeno granted Odoacer the distinction of patrician, he also urged the king to accept Julius Nepos back as emperor in Italy. Though Odoacer nominally accepted Nepos as his sovereign, minting coins in his name, Nepos was never able to reoccupy Italy. Later life Odoacer spared the life of the young Romulus on account of his "youth and beauty". Romulus was granted an annual pension of 6,000 solidi (the normal income of a wealthy Roman senator) and granted an estate in Campania near Naples called the castellum Lucullanum (today called Castel dell'Ovo), originally built by the consul and general Lucius Licinius Lucullus in the 60s BC. Castellum Lucullanum had once served as the retirement villa of Tiberius (14–37), Rome's second emperor. By late antiquity, castellum Lucullanum must have been fortified, and it likely functioned as a small administrative and military centre in Campania. Romulus was accompanied to Campania by a large retinue and some of his surviving relatives. Romulus may have been alive as late as 507 or 511, when Theodoric the Great, Odoacer's successor as king of Italy, wrote to a "Romulus" to confirm a grant made to him and his mother by Petrus Marcellinus Felix Liberius, the praetorian prefect of Italy, on Theoderic's authority. Per Thomas Hodgkin, who translated the letter in 1886, the identification of Romulus in the letter as Romulus Augustus is strengthened by the name "Romulus" by this point not being very common and by the letter not giving the Romulus in question any titles or honorifics. The absence of titles differentiates the letter from the vast majority of other letters preserved from Theodoric, as if neither the king nor his scribe were quite sure how to address a former emperor. If the Romulus in the letter is the same person as Romulus Augustulus, it is possible that the letter indicates that Romulus and his family had to renegotiate their financial arrangements and pension with the king, seeing as they had been drawn up under the reign of a different king. Given that Romulus is not mentioned in accounts of the later eastern Roman invasion of Italy in the mid-530s, he had likely died some time before the conflict. Romulus may have played a role in founding a monastery around the remains of Saint Severinus of Noricum at castellum Lucullanum in the
