I dropped into Oxford today on the way home from a friend’s, and found my way into Blackwell’s – the university bookshop. And down to the Chinese history section, where I came across an intimidating-looking tome called To become a god: cosmology, sacrifice and self-divinisation in Early China. And with about 7 minutes to closing time, took it over to the desk to find out what it cost. £17. Hmmm. On the one hand the chapter headings are fascinating: ‘Transforming the spirits: sacrifice in the Shang’; ‘A moral cosmos: Zhou sacrifice and the Mandate of Heaven’; ‘Spirits within humans: the issue of shamanism in early China and early Greece.’ On the other hand, these are 300 very dense and scholarly pages, and what are my chances of getting through them without getting lost?
