Jupiter




According to Roman mythology, Jupiter was the most powerful god. His equal in Greek Mythology is Zeus. Jupiter was married to Juno (Hera in Greek mythology), and they had a daughter named Hebe. Jupiter controlled the weather, and was usually represented with a lightening bolt in his hand. Since the Romans knew Jupiter was an all-powerful god, they believed he knew the past, present, and future, and that he would send signs to the people of Rome. It is also believed that Jupiter rides a white chariot pulled by four white horses.

Io



In Greek mythology, Io was one of the beautiful daughters of the river god Inachus. Juno had caught Jupiter and Io together by the river. Io had sensed Juno coming, so she changed into the form of a calf. Juno was suspicious, and asked Jupiter if the calf could be given to her as a gift. Jupiter didn't want Juno to find out who the calf really was, so he agreed. Juno had Io watched by Argus, who had a hundred eyes in his head. Io watched by his for a long time, but eventually was able to break free with a little help from Jupiter's friend Mercury.

Ganymede



Ganymede was once a handsome young boy who was spotted by Jupiter. Jupiter recognised his beauty, and thought it best to bring Ganymede up to the heavens with him to serve as a cupbarer. Zeus transformed into an eagle and carried Ganymede up with him. Ganymede is also known as a a servant of the gods.

Callisto



In Greek mythology, Callisto was an attendent of Zeus'(Jupiter) daughter, Artemis. She had a son with Zeus, which was named Arcas. The story goes that Hera(Juno) was jealous of Callisto, and changed her into a bear. Arcas was unaware of this, and went out hunting. He found his mother in bear form, but didn't know it was her, when he tried to kill her, Zeus saw what Hera had done, and put both Callisto and Arcas into the heavens as Ursa Major and Arcturus.

Europa



In Greek mythology, Europa was the beautiful daughter of of the king of Phoenicia. Zeus had spotted her one day and fell for her beauty. He turned into a white bull and approached her. She eventually trusted the bull enough to get on his back, but once she did, Zeus flew them to an island. On the island, Europa gave birth to Zeus' three sons, and Zeus gave Europa three gifts. Then he set a bull in the stars, as the constellation Taurus.
