Even though crows were not well thought of, they were viewed as holy because of the connection between them eating carrion and the action of piercing flesh in battle. They thought this was noble. The Celtic god of war, Bodb, was believed to change into a crow when he flew over battlefields. In Gaelic, Bran means crow, and Bran was also the name for the god of sailors. Many Celtic sailors carried crows on board their boats as good luck, and if they ever got lost at sea, they could release the crow, and it would head for land.
Crows also appear at various times in the Bible.
In the story of the great flood, Noah sends out a crow while at sea to search the vast sea for some dry land. Later the crow returns, but neglects to tell Noah that the flood has ended. Because of this, crows were viewed as selfish. It is also believed that in Paradise crows were beautiful almost tropical birds, but when Adam and Eve were thrown out of Paradise, crows began to eat dead animals and that is why they became black. It is believed that crows will again become beautiful tropical birds.
