In the first great age of English scholarship, to write history was to write polemics. England was a legal, not a geographical expression; to write her history was to interpret her law, or the relation of that law to the Crown, and so to take sides in the battle of parties. The law was timeless; its principles were the same in all ages; the past was a storehouse, not of mere examples, but of authoritative precedents. A statute whose making was ‘beyond memory’ was of greater authority than one whose beginnings were known. What the constitution was it had always been and to define its past was to define its true nature in the present. No scholar wrote more openly to support a cause than Dr Robert Brady, who was Master of Caius College from 1660 to 1700 and defended the Stuart monarchy with his learning in the last ten years of its existence; but the paradox of his career is that no man did more to bring to an end the climate of thought in which his work had been born. An interpreter of history in an age remembered rather for great textual scholars, he was a principal agent in bringing English historical method out of its medieval and into its modern period. For the student of English historiography in its peculiar and intimate connexions with legal and political thought he is, therefore, a notable figure.
