The intensi cation of melancholy in the landscape inheres in the eternal dialogue between nature and culture. Weathering, patina, ruination, are all traces of this conversation, transcripts of the exchange. A further dimension to these traces is the profoundly poignant submersion of culture by nature. Inundation is an ephemeral condition, where culture and nature melt together, not necessarily ruined, nor complete. Submersion confounds boundaries, inverting, eroding, removing the datum. The condition of submersion is ambivalent and poignant. Volcanic eruptions, sand, silt, water, colonisation by plants – all of these incursions erode the edges, blurring thresholds of containment. The drowning of culture by nature disturbs the certainty of existence.
