So, I finished off my route along the uncompleted sections of the paths, and by then felt a bit lost, with all the turning around and circling. I headed in what I hoped was the right direction, wondering if I'd spot a landmark, and then realised that the giant hill I was right next to was the man-made iron age fort of Stokeleigh Camp, and of course I knew where I was. D'oh. Sometimes you really can't see the wood for the trees.

I was put into something of an altered state by the little pilgrimage to this random little area of the woods and my backwards-and-forwards wandering. This kind of state has been used, apparently, as a form of divination, which is something I've been researching a bit recently.

It took me a while to find the right term. At first I thought that divination through walking along my map routes might be cartomancy, by comparison with cartography, but of course the "cart" comes from the Latin for "card", so cartomancy covers divination by cards, like the Tarot. Then I thought perhaps geomancy, what with it being somewhat geographical, but the "geo" bit is "earth" in Greek, and geomancy covers, as Chambers says, "divination by shapes formed, eg when earth is thrown down onto a surface".

In the end I tripped over the right name: ambulomancy—"any of various forms of divination that involve walking, often in circles", according to Wictionary. Lexico puts its appearance as early 19th century.

Of course, presumably one actually has to divine something to be an ambulomancer, and the main thing I was divining was that there was coffee and and sandwich in my future now I knew I was near the Leigh Woods exit that would take me across the bridge to Clifton Village.
