From Achilles to Zephyr, from Abraham to Ursula, The Gallery Companion provides a complete background to the classical and biblical knowledge necessary for a fuller appreciation of paintings.
Marcus Lodwick has a doctorate in ancient Greek architecture from the University of Oxford. He is currently engaged on further Classical research, and frequently leads archaeological tours to the ancient sites of the Greek and Roman world.
A very handy art guide to bring with you to the museum. It's useful for looking up subjects and symbols in Greek and biblical paintings. I recommend this book for artists and classical art lovers!
A nice compact guide to 150 of the classic paintings from the Western Art canon (no, not cowboy art! Though there's a fine tradition; I was impressed with the The National Cowboy and Western Heritage Museum in Oklahoma City, OK). Major themes, contextualization with previous & following works, and artist are explored, briefly. There are good, albeit small, color pictures of the paintings.
It's not really a guide to Western Art. It's less about the art than a guide to Greek Myths & Biblical stories - the barebones of the dramatic myths & stories - with the drama of a good story sucked out. Makes you want to read more or revisit those stories though.
