My bedtime reading at present is SPQR: A History of Ancient Rome by Mary Beard. I am enjoying this, reading it slowly to chew over all the information. As described in this review, the book is engaging - but I was delighted to find a FutureLearn course covering the development of Rome from Dr Matthew Nicholls of Reading University Classics department.

The course started today, and it is quite a revelation. These free online courses are amazing. I have thoroughly enjoyed most of the ones I have pursued.
