Typical Legend
Many of the legends of the Middle Ages associated with Architecture are reminiscent of the early customs of sacrifice in the oft-repeated traditions of demoniacal aid. The story generally deals with some difficult problem in design or construction for the solution of which the architect or builder enters into the usual compact with the evil one, the terms being that the latter party to the contract shall take possession of the first living being that enters into or crosses the structure.
Invariably the enemy of mankind is outwitted, a dog or some other animal being the first to enter, the builder’s sense of caution being in every instance greater than his vanity.
Similar in idea was the Hebrew custom of the scapegoat, which also anticipated and symbolised the Atonement.
With the Greeks the cock was not sacrificed, it being sacred to the Sun and Moon, as it announced the hours.
The cock was also sacred to the Goddess of Wisdom and to Æsculapius. Therefore it represented Time, Wisdom and Health, none of which should be sacrificed.
