Pseudo-Nero
One of the things that led to the belief that Nero survived was the fact that he died in a location that was not well known. Suetonius wrote that Galba's freedman Icelus saw the dead emperor's body and reported back to his master. Nero was also denied the lavish burial that was accorded to popular emperors and members of the imperial family.  This may have left those plebeians who loved him dissatisfied and suspicious. Furthermore, he was not buried in the Mausoleum of Augustus with the other Julio-Claudian emperors, but in a tomb on the Pincian Hill at the family burial place of the Domitii Ahenobarbi. Many Roman plebeians  though Nero was very popular after his death, and  so they laid flowers at his tomb.
