* AlternativeCharacterInterpretation: What exactly is the protagonist? A lost man trying to make the best of a situation? Or a man without respect for traditions, culture and history, trying to transform England into the next ([[TimeTravelTenseTrouble first, whatever]]) United States with a jingoist POV? Or both/none?
* AmericansHateTingle: Predictably, this book was controversial in Great Britain for its [[GenreDeconstruction unfavorable]] [[{{Satire}} depiction]] of Myth/ArthurianLegend, with the 1929 edition noting that it considered the book "a direct attack on [its] hereditary and aristocratic institutions". [[InsultBackfire To which Twain would, of course, heartily agree.]]
* {{Anvilicious}}: Monarchy and aristocracy are bad. Chivalry is a sham. Religion is the enemy of science.
* FridgeBrilliance: King Arthur's reign was remembered as having been a "golden age" because Hank's technology made people's lives better during it.
* OlderThanTheyThink:
** A plot where protagonist in the "modern era" falls asleep and finds themselves transported to the golden age of Myth/KingArthur, only for the story to satirise the setting as backwards and illogical compared to modern sensibilities - this was all done before in ''The Dream of Rhonabwy'', one of the tales in the ''Literature/{{Mabinogion}}''.
** This is one of the oldest examples of the TrappedInAnotherWorld literature genre, being OlderThanRadio.
** The myth that knights were so heavy that they had to be hoisted upon their horses by a crane is attributed to this book, but the first known instance of this gag is in a ''Punch'' magazine of 1843. The trope is [[ZigZaggedTrope Zig-Zagged]] because the book only mentions a "derrick" in passing; it was the 1931 film adaptation that fully milked the idea for laughs.
