The historic view of the Fians is taken by the annalists, by Keating, O'Curry, Dr. Joyce, and Dr. Douglas Hyde.[506] According to this view, they were a species of militia maintained by the Irish kings for the support of the throne and the defence of the country. From Samhain to Beltane they were quartered on the people, and from Beltane to Samhain they lived by hunting. How far the people welcomed this billeting, we are not told. Their method of cooking the game which they hunted was one well known to all primitive peoples. Holes were dug in the ground; in them red-hot stones were placed, and on the stones was laid venison wrapped in sedge. All was then covered over, and in due time the meat was done to a turn. Meanwhile the heroes engaged in an elaborate toilette before sitting down to eat. Their beds were composed of alternate layers of brushwood, moss, and rushes. The Fians were divided into _Catha_ of three thousand men, each with its commander, and officers to each hundred, each fifty, and each nine, a system not unlike that of the ancient Peruvians. Each candidate for admission to the band had to undergo the most trying ordeals, rivalling in severity those of the American Indians, and not improbably genuine though exaggerated reminiscences of actual tests of endurance and agility. Once admitted he had to observe certain _geasa_ or "tabus," e.g. not to choose his wife for her dowry like other Celts, but solely for her good manners, not to offer violence to a woman, not to flee when attacked before less than nine warriors, and the like.
