A Companion to Ancient History,Blackwell Companions to the Ancient Worm （Yan Shaoxiang）.

I am wondering if we should have more Companions in ancient history in the 21^st century since we already have numerous companions from the Cambridge Companions and Brill Companions, both series very focused and up to date. The Edinburgh Companion to Ancient Greece and Rome （2006） contains a variety of information about the classical world which makes it a useful handbook, and also in Blackwell＇s Companions, quite a few Companions have appeared since the new century, covering ancient history. So far as this paper is concerned, we may list the Companions to the Ancient Near East, Archaic Greece, the Classical Greek World, the Hellenistic World, the Roman Republic, the Roman Empire, Late Antiquity, the Roman Army, and Julius Caesar, all of which combined together cover almost every historical stage of ancient history chronologically. Is there any further space left for a Comnanion to Ancient History？
