Based at the University of Oxford, this site collects images from the Roman territories, from 300 BC to the beginnings of Islamic rule in the 7th Century AD. Indexing is in both English and Arabic. The site is under continuous development.
Duke University Libraries' Art History Librarian, Lee Sorensen, designed this carefully curated section for his larger guide on images, listed below. It explains and provides links to many considerations, among them fair use; legal issues, including links to laws in the EU; liars and hacks, as well as permission forms.
