Pallas Athena (or more commonly known as Athena) was a goddess in Greek (Athena/Athene) , Roman (Minerva), and (possibly) Trojan (Pallas Athena) religion. She is the goddess of wisdom, courage, inspiration, civilization, law and justice, just warfare, mathematics, strength, strategy, the arts, crafts, heroic endeavor, and skill. Athena was often a companion to heroes.
The name Pallas Athena comes from the myth that Pallas was an entity on their own (legend isn’t clear on relation, but could be sister, father, half-sister, cousin, or a close childhood friend). In the legend, Athena accidentally murders Pallas, and takes the name for herself out of guilt.
All the gods and goddesses were invited to the marriage of two mortals (Achilles’s parents). All except the goddess of discord, Eris. She was unhappy so she brought a golden apple labeled “to the fairest” and threw it to the goddesses Athena (Pallas Athena), Hera, and Aphrodite (Cypris) who all believed they were the fairest. Unable to decide amongst themselves, Zeus appointed Paris, a Trojan prince, to decide. Hera promised him control over Europe and Asia. Athena promised him wisdom in battle. Howoever, Aphrodite promised him the love of the most beautiful women in the world, Helen of Sparta. Paris picked Aphrodite, and Helen’s (Menelaus’s wife) abduction was the cause of the Trojan war. As patron goddess of Athens she fought on the side of the Greeks, however, she disliked fighting unless for a good reason. Her uncle, Poseidon, (with whom she was in disagreement with) sided with Troy.
It should also be noted that Athena then turned on the Greeks after the rape of Cassandra in her temple, and that it affected her not only for the disrespect, but another god had attempted to rape Athena as well.
