As ever, I have made sure that I walked the ground on which the novel is set. I can vouch for the discomfort of those marshes in the delta, and the searing heat of the upper Nile! The ancient ruins are also well worth a visit and I could not help but be in awe of the civilisation that had created such vast monuments long before an obscure settlement on the banks of the Tiber even came into existence. For readers who want to experience Egypt for themselves I would heartily recommend a trip to Luxor (Diospolis Magna). Many of the locations mentioned in the novel are still there and, with a little imagination, can be viewed just as Macro and Cato would have seen them.
