• deep time - see Cladistics

• incidental moments (a pot broken upon a tiled floor)

• intimate senses of history and historicity - the thumbprint upon the pot

• percolating (multi)temporality - times past present in their material traces - the palimpsest of landscape - topological folding

• the uncanny - times past coming back to haunt, returning as it never was

• actuality - the juxtaposition of presence

• decay, ruin, entropy - what becomes of what was

• fragments that hang on

• loss and trauma

• recollection and recovery

• place/event - this happened here
