The remote and inhospitable landscape of Iceland made it a perfect breeding-ground for heroes. The first Norsemen to colonize it in 860 found that the fight for survival demanded high courage and tough self reliance; it also nurtured a stern sense of duty and an uncompromising view of destiny. The Icelandic sagas relate the adventurous lives of individuals and families between 930 and 1030, which began as spoken tales but were skilfully documented in the thirteenth and fourteenth centuries, and are now regarded as written literature.
