With a grant from the National Endowment for the Humanities, professors John Wall and David Hill and architect Joshua Stephens are working to virtually replicate the architecture of the old St. Paul’s Cathedral to recreate what early modern Londoners would have heard on that day. Their model of the structure is based on the work of John Schofield, an archaeologist who works for St. Paul’s, who has surveyed the foundation of the old cathedral, which is still in the ground though partially underneath the existing cathedral. To recreate the experience of hearing Donne’s sermon, linguist and historian David Crystal is working with his son, the actor Ben Crystal, to craft a reading that will follow the specific accent and style of 17th-century London English. Ben will make his recording in an anechoic (or acoustically neutral) chamber. Wall, Hill, and Stephens — together with Ben Markham, an acoustic simulation specialist in Cambridge, Massachusetts — will then be able to mash up that recording with the architectural design to simulate how Donne’s voice would have traveled when he stood in the churchyard. They are also mixing in ambient sounds that would have been common in London at that time, such as neighing horses, barking dogs, and running water.
