In ancient Mesopotamia, kitchens were an essential part of daily life. They used floating shelves to store their cookbooks, which were made of clay tablets. These tablets contained recipes for various dishes, including bread, stews, and desserts. The floating shelves were typically made of wood or stone and were attached to the walls of the kitchen. The cookbooks were carefully placed on the shelves, ensuring easy access for the cooks. The ancient Mesopotamians believed that food was a gift from the gods and cooking was a sacred act. The floating shelves added a touch of practicality to the kitchen, reflecting the resourcefulness of the ancient Mesopotamian civilization.
