The king covers the crag with cloughes full high,
To the crest of the cliff he climbes on loft,
Cast up his umbrere and keenly he lookes,
Caught of the cold wind to comfort himselven.
Now he moves his might with mirthes of herte
Over mountes so high, those marvelous wayes,
Gos in by Goddard, the garret he winnes, Mt. Goddard watchtower
Graithes the garnison grisly woundes! Deals garrison
When he was passed the height, then the king hoves
With his hole batail beholdand about,
Lookand on Lumbardy and on loud meles:
‘In yon likand land lord be I think!’
(3103–9)In the Alliterative Morte Arthure, a poem composed in English by an anonymous poet at the turn of the fifteenth century, the above two passages describe Arthur's experience of what we would today term ‘mountaineering’: the physical act of climbing a mountain or promontory. The brevity of these passages, in contrast to the ever-expanding body of literature on mountain ascents since the advent of Alpinism, is one example of the radical shift in our attitude towards mountains in recent centuries. For many in the modern world, mountains are a source of pleasure, excitement, wonder and escape, in a way that would seem alien to our medieval forebears. And yet mountains and hills are as much a part of the medieval world as they are our own, linked to worship, military strategy, defence, geopolitics, agriculture, industry, travel and commerce. In art and literature, they serve as sites of contemplation, as figurative embodiments of worldly and spiritual power, and as otherworldly landscapes associated with monstrosity and otherness. In the specific context of the medieval Arthurian tradition, the primary focus of this essay, they are also linked to the figure of King Arthur.
