Two hundred and fifty-four years ago, it was documented that four Majorcan pounds were spent on “thunderclaps and small wheels”. The purchase had been authorised by what, in effect, was the managing board of Sant Bartomeu Church in Montuiri. The small wheels were “rodelles”. On Friday night, the rodelles will take pride of fiestas place, as they have done for so many years. The current-day version looks almost like a propeller. The thunderclaps emanate from it as it spins around. Below the spitting fire is a demon who trots up and down.
