Only 30% of ancient Greece's land was arable, meaning that crops were able to be grown on it. Ancient Greeks grew olives, grapes and barley.
Olives.....
Olives were very important to the ancient Greeks. They used olives for eating and to make olive oil, which they used for cooking and as a lubricant.
Grapes......
Grapes were also a very important crop for the ancient Greeks. From grapes, the Greeks made wine. The common drink of everyone was a mixture of wine and water. Even children drank it! Dionysos was the mythological god of the vine, meaning he oversaw and blessed everything having to do with growing grapes and making wine.
Barley.....
Barley is a type of grain that was used in the same way as wheat. It was used to make bread and was a staple part of the Greek diet. Demeter was the mythological goddess of grain.
Livestock!
The ancient Greeks kept chickens, pigs, sheep, and goats (for milk and meat). Ancient Greeks would only eat meat of animals who had been sacrificed, meaning killed in the name of a god. Generally, Greeks did not eat a whole lot of meat, but instead depended on fish (since they are so close to the ocean) and legumes for protein. Legumes are bean, chickpeas, and lentils.
