As down the steep of Snowdon's <note xmlns="http://www.tei-c.org/ns/1.0" place="bottom"> <emph>Snowdon</emph> was a name given by the Saxons to that mountainous tract, which the Welch themselves call <emph>Craigian-eryri</emph>: it included all the highlands of Caernarvonshire and Merionethshire, as far east as the river Conway. R. Hygden[,] speaking of the castle of Conway built by King Edward the first, says, ''Ad ortum amnis Conway ad clivum montis Erery [At the source of the River Conway on the slope of Mt. Erery];'' and Matthew of Westminster, (ad ann. 1283,) ''Apud Aberconway ad pedes montis Snowdoniae fecit erigi castrum forte [Near (<emph>or</emph> at) Aberconway at the foot of Mt. Snowdon, he caused a fortified camp to be constructed.].'' </note> shaggy side
