"The Devil's Coach Horses" is a 1925philological essay byJ. R. R. Tolkien ("devil's coach horse" is the common name of a kind ofrove beetle).[1]
Tolkien draws attention to the devil's steeds calledeaueres inHali Meidhad, translated "boar" in theEarly English Text Society edition of 1922, but in reference to thejumenta "yoked team, draught horse" ofJoel (Joel 1:17), in theVulgata Clementinacomputruerunt jumenta in stercore suo.[2]
Rather than from the Old English word for "boar",eofor (GermanEber) Tolkien derives the word fromeafor "packhorse", from a verbaferian "transport", related to Middle Englishaver "draught-horse", a word surviving in northern dialects. The Proto-Germanic root*ab- "energy, vigour, labour" of the word is cognate to Latinopus.
