Conceptual Sequences II

I mentioned a time travel conceptual sequence: Wells/de Camp/Ward Moore/Anderson. This sequence began with two pre-hard sf, pre-technological time travel stages:

"Missing One's Coach: An Anachronism," Anonymous, 1838;
A Connecticut Yankee In King Arthur's Court, Mark Twain, 1889.

(The Time Machine was 1895.)

"Missing One's Coach" definitely describes pastward time travel but is possibly a dream. The Connecticut Yankee tries to change if not the course of history, then at least the unrecorded course of events in an obscure period.

Being pre-Wellsian, they lack the language of "time travel." "Missing One's Coach" is "An Anachronism," involving "...a fault in the strata of time...," while the Yankee experiences "transposition of epochs."

Although I found A Yankee... implausible and almost unreadable, it is a major part of the sequence and Anderson cited it as an influence.
