This strange mosaic is known as the Lod mosaic. It was named such since it was discovered in the city of Lod in Israel. Serious creative thought was put into the naming process.
Although it looks small in this picture, the Lod mosaic is some 50 by 30 feet. It is actually the floor to a Roman house. It is also quite a mystery to scholars who have yet to determine whether this mosaic is Christian, Jewish, or Pagan. After looking at various close ups of the images, I can see why. The mosaic has an odd mixture of animal pictures. There are angry, vicious looking beasts. But then there are animals with goofy smiles. There are a number of hunting images, with beasts killing other beasts. There are also a number of fish depictions. Fish eating fish. Fish around a sailing vessel. Fish in a basket. I was beginning to think this was the floor of a Roman fisherman and hunter, the mosaic being his version of a trophy case. Then I found the answer.
If you look very closely at the image between the two lions, just above the elephant’s head, you will see the key to solving the mosaic mystery.
Yes. That’s right. It’s Scooby Doo.
