In Greek mythology, Ara is the altar where Zeus and his brothers and sisters said that they were going to win in a war against Cronos and the other Titans. It is also where people burned incense to show that they appreciated Zeus. The Greek poet named Aratus said that if sailors could see the constellation Ara, it meant that there was going to be wind blowing from the south.
