Reddit reviews Art History: A Very Short Introduction

I have a few recommendations for you:

1. First and foremost, Khan Academy's Art History section. It's absolutely wonderful and comprehensive, with videos on each era (which may be a bit more in depth than you need) and summaries of each era and the important points about them. The narrators do a great job of keeping it engaging. I've dropped quite a few hours on there. And best of all, it's free.

2. A Very Short Introduction: Art History
   
   These AVSI books are really great when you like a quick overview of a topic. They're usually 100-150 pages in length and generally pretty high quality. I wouldn't be scared away by the reviews on any of them, the books are all written by professionals and most of the reviewers are highbrow snobs. Cheap and short, so you don't have much to lose. I've read about 10 of them and have yet to be disappointed.

3. Gardner's Art Through the Ages
   
   This one is a textbook, so a bit more in depth. If you have access to a good library, you might be able to find it. But it's very well written and provides summaries of the important art historical eras along with beautiful photos and explanations. The book is a work of art in and of itself.
   
   Best of luck!

Dana Arnold's Art History A Very Short Introduction is a great short book to give you an overview; others have pointed you to Khan Academy and the BBC's A History of Art in Three Colours is a great 3 part documentary and personally I adore Waldemar Januszczak's documentaries take your pick from a variety but a really good one is Paradise Found and here's a bunch of available free short courses

oxford university press do a series called 'very short introduction' covering alllll kinds of topics, and the art history one is brilliant, there's also art theory and then others on particular artistic/creative movements - they're really affordable and really easy to read and actually so informative
