CIRCA | 2018
CIRCA is a light sculpture that represents the circannual cycle of light levels on earth’s surface in southern England. It is divided into twelve physical elements, circles, that each represent one month of the year. The total circumference of each circle represents a twenty four hour day, the amount of daylight hours are displayed through the percentage of the circumference that is lit up. Light is the primary zeitgeber (time-giver) and is therefore the most responsible factor for setting endogenous clocks in plant, animal life and humans.
