I was surprised to notice, when exploring Wikipedia's Epithets in Homer, that Agamemnon's individual epithet (or at least one of them) was "son of Atreus (Ἀτρείδης Atreídēs: also transliterated Atrīdēs)". That made me look into the House Atreides in 'Dune', and Wikipedia's Paul says:
According to Brian Herbert, Frank Herbert's son and biographer, House Atreides was based on the heroic but ill-fated Greek mythological House Atreus.
Though this is not sourced.
The Wikipedia's Paul further adds:
A primary theme of Dune and its sequels is Frank Herbert's warning about society's tendencies to "give over every decision-making capacity" to a charismatic leader. He said in 1979, "The bottom line of the Dune trilogy is: beware of heroes. Much better rely on your own judgment, and your own mistakes."
This makes it sound as if the link between Agamemnon and the Atreides is concrete, and an example of why heroes are not the best people to follow in everything. Agamemnon himself, after all, is a very complicated character though almost certainly over-haughty. How relevant are these links?
PS. It's interesting that the Atreides' link symbol is a red hawk, as below. Is this also linked to Greek mythology (the eagle being a symbol of Zeus)?
