Klaus said:Gygax mentions the chansons-de-geste as an influence over the Paladin, and I believe we'd still see a paladin akin to the original form of the class.
Have you read any chansons de geste? Or even Orlando Furioso? The paladins of Charlemagne were just fighters. Nothing holy about them, except that Turpin was a bishop. Paladins picked up some of their holy abilities from Lancelot, Perceval, and Galahad. But most of their flavour comes from Holger Carlson in Poul Anderson's Three Hearts and Three Lions (who was, indeed, supposed to be a reincarnation of Charlemagne's paladin Ogier the Dane, but owed nearly everything to Anderson's imagination and almost nothing to literary borrowings from the chansons or Ariosto).
Now, Three Hearts and Three Lions was published before Lord of the Rings. But in 1953, only a few months before The Fellowship of the Ring came out. It would not have been availableto influence paladins as it unquestionably did in the '30s scenario we are asked to consider.
Three Hearts and Three Lions also contributed alignment and regenerating trolls.
