I've read Philo's
Embassy to Gaius, which also contains the only surviving eyewitness account of Caligula's personality.
In that work, what I see is mainly
,
,
; an awareness of
; not much concern with
, and some
.
When Philo really "lets go", what he seems to be most proud of is an ability to penetrate beneath the surface of people's actions, to see what they are really up to.
So I think Beta is clear; being more specific, I'd have to say EIE. I don't think LSI; I think a good example of an ancient LSI is Tacitus, and his writings are more
and
, and less
, than Philo's.
