James Canton is an author and lecturer whose writing is mainly concerned with the ties between nature, literature and the environment. Often involving exploring the distant past, his books include Ancient Wondering, From Cairo to Baghdad, and The Oak Papers. His most recent book Grounded takes him on a journey through England, considering the private markers in the landscape which are sacred to individuals and which connect us to the people from our past. In this episode of Nature Revisited, James reveals how our ancient ancestors were not as primitive as we might imagine, as well as what we can learn from - and how we're connected to - the sacred sites and grounds of our landscapes.
