ABSTRACT
This chapter summarizes the sequence of findings from the earlier parts of the study. For any theory of design to be tenable, however, it must be capable of implementation. The chapter shows that how the system of Platonic geometry proposed here could have been translated from tracing-house to building site. It demonstrates how a planning grid can be produced, translated to site and converted into a dimensioned building plan in four stages in a manner supported by medieval evidence. The chapter also demonstrates that a schematic design based on geometric proportion could be translated from tracing-house to building site and into a dimensioned building plan complete with its architectural details within the known working methods of medieval masons. Just as Noah's Ark stands as a biblical model of salvation, so the octagonal shrine stands as an architectural model in which number, geometry, liturgical function and inaugural dedication come together in signifying salvation architecturally.
