Like the Fertile Crescent, Crete had rich soil, a warm climate, and plenty of water. With less time spent fighting to live, the Cretans began to make complicated things. From the wild crocus flowers which covered their island, the Cretans collected saffron used in yellow dye, in food, and in medicine. From the Egyptians, they received rich cloth and jewels. From the Hittites, they learned how to use iron. From the wealthy Lydians, they learned to use money. From Phoneicia, the Cretans received the alphabet which is used today.
