Most of the immortals changed their names as time passed. I used to think it was to protect themselves from the humans discovering how old they were. But I’d changed my hypothesis lately. I think after a long time, some people grew tired of themselves. A new name gave them a chance to reinvent who they were, to become someone else, some other kind of person. Or sometimes, as in Iacopo Bonarata’s case apparently, they decide to pick a name easier for their soon-to-be minions to say.
