While all this and much more besides is true, it makes the assumption that Red Seas is about actual 'historical' mythology, rather than evoking a pop cultural, and specifically '50-70s movies, version of same.
I believe Colin (and perhaps the Cosh?) to be our pre-eminent Red Seas scholars - perhaps if YNWA could spare a moment from his endless tabulations he could offer an insight?
For my own thruppence: Erebus is a cool name, in Greek myth the child of Chaos himself and a dark part of Hades' realm, and while it clearly is intended to call Cerberus to mind when used in conjunction with a multi-headed dog who is instrumental in the guarding of the nether/afterworld, it's enough to set this particular urbane clock-punk hound apart from his more animalistic namesake, while suggesting that what we think we know about Cerberus and his role may not apply.
As an aside, one of my beefs with many 'Mythological characters in modern days' stories is that IF they are true to their (contested, polysemous, partial) mythological origins, then their stories are known or done. I point a withering finger of judgement at Percy Jackson (film versions) in this regard, and raise a glass of a moderately priced Malbec to Eddie Campbell for navigating that fine line.
Better in general to present a story that uses the keywords, but writes a new mythology around them without pretending faithfulness.
