Azar Saiyar ponders over what remains and what gets lost when things become museum objects. Many details have gone missing, but the museum objects of the Satakunta Museum (Pori, Finland) still carry the strong presence of the water that runs next to it: things that the river and the sea have carried, that were born, that live or once lived because of their proximity. Aurinkokirja is a meditation on the presence, erosion and transmission of perceptions.
