The Constellation Hercules
Lots of Brawn But...
Not Very Bright



The constellation Hercules is big in size but... not very luminous. Hercules is the fifth largest constellation but its brighest stars are only of the low second or third magnitude. This makes this constellation hard to spot for the inexperienced stargazer.

Originallly known as Heracles to the Greeks, Hercules' name was changed by the Romans.

As the son of the god Zeus and the mortal woman Alcmene, Hercules came under the wrath of Zeus' wife Hera. She attempted to kill the baby Hercules by sending two giant snakes to attack him in his crib.

Already possessed of great strength Hercules was able to strangle the snakes and save his life. Eventually Hercules was sent out to perform his famous twelve labours. These tasks were thought to be impossible to accomplish and Hera thought that surely Hercules would be killed.

The twelve labours are as follows:

1.slay the Nemean lion Leo.

2.slay the 9-headed Hydra. During this fight Hercules killed Cancer the Crab.

3.capture the golden hind of Artemis.

4.capture the Erymanthian boar.

5.clean the Augean stables in one day.

6.slay the Stymphalian birds Lyra, Cygnus and Aquila.

7.capture the Cretan bull, which some believe to be Taurus.

8.steal the mares of Diomedes.

9.obtain the girdle of the Amazon queen Hippolyta.

10.obtain the cattle of the monster Geryon.

11.steal the golden apples of the Hesperides.

12.capture Cerberus.
