黑、红、绿：方法论

The bohemian was a stickler for order. He filed, sorted, annotated maps, built up dossiers, expanded his documentation. His method came down to five steps he never departed from: plotting the route on the map, reading the encyclopaedic literature, listing the monuments and sites along the way, scouting on the ground with a recorder, then writing up the notes.

The write-up was done with coloured pens: black for the route, red for history and archaeology, green for geography. Nothing was left to chance. A quarter of an hour of television represented about a month of work.

To reach everywhere he drove a small French car whose suspension he had raised by five or six centimetres, a Renault 6 turned off-roader. That is how he found that the Hesbaye, where every good author swears there is nothing to see, is remarkably rich for anyone who loves space and history.

Bernard Mahy remembers his father's anger at his recorder: a delay of a few thousandths of a second between pressing the button and the actual start of the recording seemed unacceptable to him. Bernard himself would answer philosophically that technology would eventually fix this flaw. Today, devices start to the nearest thousandth of a second, and Bernard imagines his father would have savoured these feats.
