On the morning of 20 January 1658 the members of the Other House gathered at Westminster for the opening of the second session of the second Protectorate Parliament. After taking their oaths in the Painted Chamber they filed into the former House of Lords and were seated ‘by a herald at armes after the wonted manner there’. The faces of those occupying the benches were new, but the chamber looked much as before.

Instead, Fiennes urged compromise. Given the ‘great variety of humours and judgments’ among the people of the nation, he thought it ‘no wonder’ that ‘every one cannot have what he thinks best in his judgement’; they ought to be ‘content …
