“A day longer than a day” (2022) is a cinematic reflection on the irregular currents in the Euripus Strait, a narrow tract of water running along the coast of Chalkida (Greece). On six days during the synodic lunar month, three days after each squaring of Sun-Earth-Moon (90 degree constellation), the regular tidal forces weaken and the currents become so unpredictable that they violently change direction up to 14 times in 24 hours. This unique natural phenomenon and the associated historical process of understanding it, which begins with Aristotle, is used as a mirror for contradictory forces within the human soul.
