The structure of their societies, the management of their industry, agriculture, commerce, the size of their settlements, the subjects of their stories, everything is shaped to fit the somer-kemmer cycle. Everybody has his holiday once a month; no one, whatever his position, is obliged or forced to work when in kemmer. No one is barred from the kemmerhouse, however poor or strange. Everything gives way before the recurring torment and festivity of passion.
