consisting chiefly of light-horse, heavy-armed foot, and mercenaries
Note by H Craik to chapter 3 of Battle of the Books

The enumeration does not quite agree with that on p. 212. But in both cases the light-horse are the poets, other than epic; the foot are the historians; while mercenaries seem to be those who have little interest in the points of the struggle, but, from the accident of their date, fight on the side of the Moderns.
