The philosophical contribution of Heraclitus (535 – 475 BC) took the form of roughly 80 thought and text fragments, known for their cryptic density. His observation that the only constant is change is now given visual form by Christina Lissmann. „The Herbarium of Heraclitus“, which Lissmann contends to have discovered and for us made visible, embodies in its botanical fragility and graphic subtlety a new and visual approach to the hermetical work of Heraclitus. „The photo works show the precious collection of unique flowers and rare plants which the philosopher has collected in his isolation and was able to preserve through mysterious conservation techniques for posterity“, asserts the artist with an ironic wink. Christina Lissmann’s work finds itself in the interstice between philosophy and art.
