Abstract
A summer spent in the Scandinavian Arctic changes the sense of seasons: the Sámi know eight seasons; the visitor finds summer in the valleys, winter above, in the mountains, and winter below, in the permafrost underfoot. The summer spent in movement makes one understand the force of movement and initiative in human life, the sedentary and the nomadic instincts. The seasonal migrations of reindeer and the periodicity of lemming years make one explore movements of humans that are not launched by initiatives, periodic and rhythmic movements. Exploring rock paintings in Alta and the space station in Kiruna extends the space of human history from humans assembled at the foot of the retreating glacier, 7000 years ago, to human tourists in outer space
