PETS
Popular pets of ancient Greece included birds,
dogs, goats, tortoises, and mice. Cats, however, were not a popular choice.
THEATER
If you were a man living in ancient Greece, you
might also enjoy going to the theater to see dramas performed in honor
of the gods. Greek theaters were built outside, usually along the
slope of a hillside. All of the actors were men - they even played the
female roles! Each actor played several parts in the play by wearing a
different mask for each part.

GAMES
The Greeks took games of all kinds very seriously,
especially athletic competitions. Young men (from richer families who didn't
have to work) in most Greek cities spent a lot of their time training for
these competitions, and the best of them were chosen to compete in the
Olympic
Games against the best young men from other cities. Similar to
the Olympics of today, competitions included running, jumping, throwing
a javelin, and throwing a discus. Because games were usually run in the
nude, women were not allowed to compete or watch.
Greeks also played less active games like dice, marbles, and checkers. Even in these games, though, the competition was very important, and there was a feeling that losing at games meant that the gods disliked you.

This is the stadium at Delphi, which gives a general idea of the configuration of the stadium at Athens built in the fourth century BC. No remains of the Athenian Stadium are visible because a modern stadium was built on its site for the first officially recognized modern Olympic Games in 1896.
