It is questionable to what extent it was De Morgan's advocacy of Horner's priority in discovery that led to "Horner's method" being so called in textbooks, but it is true that those suggesting this tend themselves to know of Horner largely through intermediaries, of whom De Morgan made himself a prime example. However, this method "qua" method was known long before Horner. In reverse chronological order, Horner's method was already known to: However, this observation on its own masks significant differences in conception and also, as
