Resume : After the destruction of his tribe in a volcano eruption, Rahan moves from land to land and tribe to tribe while spreading goodwill among those-who-walk-on-two-feet, and a powerful ethic of cooperation. With his open altruism often at odds with his powerful will to survive, Rahan's ethic is encompassed by the qualities represented by the bear-claw necklace he received from his dying adoptive father, Crao: courage, loyalty, generosity, resilience, wisdom. Also, after he gets married, he receives a sixth claw, the claw of curiosity. That is well deserved, since in every one of the more than 100 stories spread over 30 years and 3300 pages of illustration (as of June 2005), Rahan uses the scientific method to pick up some bit of knowledge from nature and spin it to some useful purpose - for himself, for some human tribe or even to help some animals in distress. He comes up with the catapult, the net, the fishing pole, the lens, diverts water for use in drinking and agriculture, flies on wings of leather, uses concave mirrors to concentrate the rays of the sun to heat caves and fight rampaging animals,.... Every adventure combines the positive social attitude of a true leader with the inventiveness of a true scientist.
