He doesn't mention a post but I think you're right about the Egyptology thing.
Mind you, some of his observations are wrong...he describes an area at the delightfully named Bradenstoke cum Clack, to the W of Lynham as "a well preserved camp of rather curious triangular construction with a tumulus at its centre".

You can see where he's coming from but unfortunately MAGIC describes it as a Motte and Bailey.
