Unlike seemingly everyone else in this thread, I have actually read the first two of his series and own all the rest besides the Age of Reason.
Yes, it is absolutely worth reading, he writes with excellent prose, and gives a detailed, lifelike picture of the cultures he writes about. While new advances in archeology and historical analysis have provided some evidence which contradict specific points here and there, on the whole it is still quite accurate historically speaking, especially considering its sheer scale. Also, while there have been advances in archeology and whatnot, much of the advances made in history specifically since the writing of these books have been historiographical or philosophical in nature, and thus don't necessarily disprove his work, just draw different conclusions from similar evidence. But yeah, definitely worth a read, the chapter on Crete in the Life of Greece and Egypt in Oriental Heritage were my favourite sections.
