By Dr. Melissa Schons Bishop, Creative Classical Curriculum
Find lots of information under the Homework Help section of Mythman.comEos has excellent art; Iris explains the mythology of this goddess very well.
Eos and Iris on www.pantheon.org.  Excellent overviews of myth and its purpose in antiquity.  Note how the minor status of these goddesses is reflected in the brevity of the articles about each of them on this web site.
For a more in-depth approach to the mythology, try Parada's web page, Bulfinch's or Characters of Greek Mythology - all accessible at the Lenape Latin Mythology page.
