Artists, architects, musicians and archaeologists have all pondered the universal applicability of their own discipline and wondered at the bounty available through the dissolving of disciplinary constraints. But this paper argues that strong, speculative interdisciplinary work necessarily requires strong and vital disciplinary centres. My own interdisciplinary navigations outwards from architecture towards archaeology have explored, in particular, similarities between architectural and archaeological drawing practices revealing otherwise obscured resemblances between the purported aims of those disciplines. Central amongst these repressed similarities being the fallacy of regarding archaeology as past-facing and architecture as future-facing. This paper argues that despite these temporal teleologies both disciplines are enacted in the present and that their ostensibly unconnected practices of design and reconstruction in fact share common aims with positive repercussions for both disciplines.
