Wren was engaged also in a series of observations on the planet Saturn. These pursuits were, however, interrupted by an event that convulsed all England. On September 3, 1658, during a fearful storm which swept over London, Oliver Cromwell died. Hume[66] gives a terrible account of the state of constant suspicion and fear of assassination in which Cromwell passed the last year of his life; the secret armour which he wore, his constant guard of soldiers wherever he moved, his fears on a journey, his habit of never returning the way he had come, nor by the direct road, seldom sleeping above three nights together in the same chamber, or in any he did not choose himself, or without sentinels.

Matthew Wren made an attempt two days after Cromwell's funeral to enter the college, and sent a curious account to Christopher, who had returned to All Souls at Oxford. He writes:
