Tracking the Sun
12 marble slabs on wooden boxes, laser engraving in marble, dimensions of each object: 30×91×2 cm, 2017
The record of the presence of the Sun in a given latitude (51°06’18.6”N, 17°05’21.4”E) day after day in the year 2016. A Campbell-Stokes heliograph was used to execute the work — a glass sphere focusing the Sun’s rays on an appropriately shaped strip of paper. The rays burn a trace whose length is determined by the time the Sun operates, with an accuracy of six minutes. The drawings on 366 strips of paper were then transferred and laser-engraved on twelve marble slabs, each representing a single month of 2016.
