The Greek myth of Athena and Arachne is a myth of a wonderful contest
    in which the skills of  a goddess were matched against the skills of
    disrespectful mortal Arachne.  The young Arachne was of a very low
    status in society, and for this reason the goddess Athena took pity on her
    and taught her the art of weaving. Arachne was a very quick learner and soon she
    became a master weaver, excelling in the skill of weaving. So
    talented had Arachne become that the nymphs would gather to see her
    beautiful designs.

    all her glory
    
 People would gather in the hope of learning from
    Arachne's great skill.  Soon questions began to appear, "Arachne
    who taught you how to weave so beautifully?", "No one" would
    reply Arachne.  Arachne had become engulfed in her self-conceit that she
    could not even give credit to her teacher. However, everyone new that the
    only one who could teach her this fine art was Athena, and they could not
    understand how a mortal could have such disrespect towards a
    god.   Athena was saddened by the disrespect of her pupil so she
    decided to pay her a visit in the hope that she could make Arachne realize
    the folly of her ways. Athena came to her in the form of a very old woman
    with jagged and torn old clothes, she told Arachne that she should respect
    the gods as even the wise do, as true skill comes with age and wisdom. 
    Arachne would have none of this, why should she respect someone who in her
    eyes did not help her? She proceeded to mock the goddess and challenged her
    to an open contest.
    
Such disrespect Athena could no longer handle. Under the
    shadow of the old woman appeared the glory of the god of wisdom and war
    Athena.  All who were present trembled in fear and bowed down to the
    goddess Athena
    offering her praise except Arachne.
    
The competition then began and each competitor proceeded to
    weave beautiful masterpieces. Athena wove the story of how she won the
    competition with Poseidon for the naming of Athens. The story told of how
    Poseidon had struck the ground of Athens with his trident and brought forth
    salt water, where as Athena struck the ground with her staff and brought
    forth an olive tree. The people of Athens chose Athena as their patron
    goddess over Poseidon as they found her gift more useful to their
    city.  Along with this creation she created images of mortals being
    transformed to hideous beasts from gods as a result of their disrespect.

Arachne's disrespect
    was magnified in her marvelous design  a clear mockery of her teacher
    and the gods, she wove scenes of the brutality
    of the gods showing them in compromising situations. Athena quickly became
    angered, looking for fault in the girl's work she found none. Athena  grew angry
    and rose up hitting Arachne in the face
    with her tool. Upon being struck Arachne realized the magnitude of her
    arrogance and hung her self.
Upon seeing the death of the girl Athena
    became saddened and decided that the girl should continue to weave as should her descendants
    for all time. She sprinkled her with a magic potion  and transformed her into
    a spider.. and till this day we can find her descendants spinning their magnificent webs
    throughout world.
