I hope someone knows what I'm asking. I'll show what I have, and this is my bibliography:

Atsma, Aaron. Theoi Greek Mythology. 2007. 18 March 2008

<Link 9> <http://www.theoi.com/Ther/Sphinx.html>
<Link 10> <http://www.theoi.com/Titan/TitanOkeanos.html>

here are two examples of various quotes I used:

“depicted with horns of a bull and a lower body that is like a tail of a serpent.” (Atsma, Link 10 par. 2)

“this couple is thought to be succeeded by Poseidon and Amphitrite.”(Atsma, Link 6 par. 3)

I really need help with this!
