Seth Long takes a closer look at the number of memory treatises from 1550-1650 to come up with a more concrete reason for the disappearance of mnemonic imagery (and the method of loci) in English rhetoric and pedagogic traditions. Some writers have attributed it to the rise of more writing and publishing. Long extends Frances Yates' idea of its decline to the rise of Ramism by presenting some general data about the number and quality of memory treatises published during the time period in question. Comparison of this data with European continental publications helps to draw some more concrete conclusions.
In particular, he highlights an example of a Ramist sympathizer re-writing a previous treatise and specifically removing the rhetorical imagery from the piece.
