Episode 4

Pepys, now 70 and in poor health, has a visit from Sir Christopher Wren, who tells him of the death of an old friend, Robert Hooke. Hooke played a key role in the rebuilding of London after the Great Fire, at the time when Wren had been commissioned to redesign St Pauls. For his third design of the cathedral Wren made an enormous model, large enough to walk through, and presented it to the clergy for their approval.
