a bit of all this. there's also the fact that almost anybody can be deluded into thinking that they're basically god if they get enough praise from powerful people (which this guy clearly got). funny story: during a roman triumph (basically a festival celebrating recent militairy victories), the triumphal general would ride around wearing a purple toga and a gold diadem (ancient symbols of royalty), and generally be a pompus ass the whole time, as is his right. but there was always a young man who was paid to sit beside the triumphal general during the procession, to intermittently whisper into his ear "you're just a man" or something like that. because apparently delusions of grandeur were common in these ceremonies. so the romans mandated that a guy was there to bring the general back down to earth.
