Emory University is offering an on-line seven-week course on "The Bible's Prehistory, Purpose and Political Future" taught by Prof. Jacob Wright. You can either participate for free, or pay a little to gain a certificate. It looks worthwhile, and apparently doesn't demand any particular prior knowledge. I haven't even considered any MOOCs up till now, but am considering this one. Thanks to The Biblical Studies Online blog for drawing attention to this offering.
