Lancelot was supposedly King Arthur's premier knight in the fabled English kingdom of Camelot, even though he had a controversial reputation.
Mordred was supposedly King Arthur's evil illegitimate son who attempted to usurp Arthur's kingdom through rebellion.
Archaeologists have already posited the existence of an actual ancient city of Troy that was poetically portrayed as mythological in "The Illiad" (Homer), so it stands to reason that archaeologists would be interested in decoding real truths regarding the otherwise mythological fables written regarding the fantasy Medieval kingdom of Camelot.
There is ample evidence of course that King Arthur was an actual English monarch, so Lancelot and Mordred may have been real life figures and not simply mythology fantasy avatars.
Because Lancelot represents a romantic portrayal of Camelot, it is prudent and scholarly to find his character foil or literary opposite and in this case, this figurative pairing would suit the person of Mordred.
Lancelot and Mordred are opposites simply because they represent the dual potential of monarchy realms between obedience and ambition, which civilization archaeologists would find as reflective of the psychological marketability of history-themed movies such as "Excalibur" (1981) and "Troy" (2004).
The search for elusive Lancelot-Mordred rivalry artifacts ensues.
