Sources

I borrowed these books form the school library on the 18/8/10:

*The Ancient Greeks,M.I.Finley,1963
*A History of Greece to 322 BC,Third Edition,N.G.L.Hammond,,1959
*Ancient Greece:A Political,Social and Cultural History,S.B.Pomeroy,S.M.Burstein,W.Donlan,J.T.Roberts,1999

These books expressed some ideas behind the growth of Greek art and the way they have been changed over time.
The Verginian art fresco uses these Hellenistic art views in its concept and I thought they were quite helpful,though the few paragraphs in each book were quite short and simplified.
