Eryri, Snowdon, which some suppose derived from mynydd eryrod, the hill of eagles, but more probably from mynydd yr eiry, the hill of snow. Snowdon, in English, signifies literally the hill of snow, from Snow and Down, that being still a common name for a hill in England, as Barham Downs, Oxford Downs, Burford Downs, &c.
