In the Netherlands this is called the "Beeldenstorm" and began with the destruction of the all the images of the Monastery of Saint Lawrence in Steenvoorde after a "Hagenpreek" (field sermon) by Sebastiaan Matte, and the sacking of the Monastery of Saint Anthony after a sermon by Jacob de Buysere.
In August 1566, in the depressed industrial area around Steenvoorde a rash of attacks on Catholic church property started, in which religious statuary was destroyed by irate Calvinists, for whom those statues contravened the Second Commandment against graven images.
Early August 1566, a monastery church at Steenvoorde in Flanders (now in Northern France) was sacked by a mob led by the preacher Sebastian Matte.
