London Fields, East London. Saturday the 17th of October. A slight north-northeastern wind is blowing. The sky is overcast, with a drizzle earlier in the day making the ground slightly softer than usual, but still firm enough to get a good grip. Perfect weather for the joust to make a return, after six hundred painstakingly long years. At long last, the beautiful game is back. Here we are in heaven. Like many things in the last six centuries, the mechanics of the joust have changed. Where men used to ride on warmblooded chargers and destriers, the Fourth Industrial Revolution has had its way and transformed their steeds into equally noble Lime Bikes – the iconic green rental bicycle that plagues London’s pavements and gives transit to its most downwardly mobile residents.
