This programme commemorates the 350th anniversary of one of the most bizarre events to take place in the 17th century. The day was 12th October 1654, a normal Monday morning in the Dutch city of Delft. Painters in their studios, people working with looms and in potteries, and a man called Cornelis Soetens walks down a few steps to take a small sample from a gunpowder store. The Netherlands had never heard an explosion like it. Ninety thousand pounds of gunpowder went up in five almost simultaneous thunderous blasts. It’s reported that it could be heard as far away as the island of Texel a hundred and fifty kilometers away. At the time it was dramatically claimed that a hundred thousand cannons pointed towards the city couldn’t have done more damage. A quarter of Delft was destroyed. At least a hundred people were killed and thousands wounded. It became known as the Delft Thunderclap but, in an age of deep religious conviction, some believed that the very gates of hell had opened up and God’s wrath had rained down upon them, in what very well may have been the largest manmade blast the world had ever seen.
