With B and F at the Three Tumuli of Grimde earlier.
The Tumuli are three first- or second-century graves on the outskirts of the town of Tienen; one is known to have been the tomb of a Marcus Probius Burrus. Excavations in 1892 produced among other things a cameo of a young man, assumed to be the Emperor Augustus, which was sold to the Rothschilds, stolen by Göring, and eventually tracked down in Waddesdon Manor, Buckinghamshire, in 2007.
B and F did not care about that, and B was in an exceptionally good mood and seemed unusually lucid, though it is always hard to be sure. It was a lucky strike, in a way; the church I usually take her to was closed for some reason. We looked in on Our Lady of the Stone as well; it's only a few hundred metres away from the Tumuli.
