Can anyone recommend books or websites that include historically accurate photographs or illustrations of armor or whatever military dress was worn by the armies of the ancient world. I am interested particularly in the Spartans and Romans, though I would like to see books and sites that depict the armor of other armies as well.

I also am looking for a book about Sparta. I was considering Sparta and Lakonia: A Regional History 1300-362 BC by Paul Cartledge as it is recommended in the EB bibliography section. However there is only one review for it on amazon, so I would like to know if this is a worthwhile read or if there is another book that you would more highly recommend.

Thanks.
