Shortly after his appointment to the Treasury, Godolphin was made a Privy Councillor; and, with the Earl of Sunderland and Mr. Hyde, formed that triumvirate which was so greatly in the confidence of the King:--indeed he may be said to have already become one of the moving spirits of the age. Charles was particularly anxious that Sidney Godolphin should convey to the House of Commons his determination never to consent to the exclusion of the Duke of York from the succession; but there was an old, wise head upon Sidney's young shoulders, and, adroitly evading the task, Sir William Temple became his cat's-paw on that occasion. For a few months, in April, 1684, he succeeded Sir Lionel Jenkins, now grown very old and infirm, as a Secretary of State; and in the August of that year, on the retirement of the Earl of Radnor (whom the Earl of Rochester succeeded as President of the Council) our Sidney became First Commissioner of the Treasury. On the 8th of the following month, he was raised to the peerage, with the title of Baron Godolphin of Rialton, in Cornwall. Rialton is an old manor-house on the banks of the little stream which finds its way into the sea at St. Columb Porth. It formerly belonged to the Priory of Bodmin, was for a long time in the possession of the family of Munday, and was granted to Sir Francis Godolphin in 1663. A great part of it was destroyed by fire towards the close of the last century, and the remains of it are now occupied as a farm-house. It was built by the haughty Thomas Vivian, last Prior of Bodmin, whose initials and arms may still be traced on various parts of the picturesque remains: C. S. Gilbert, in his 'History of Cornwall' (vol. ii. p. 673), gives a view of the S.E. entrance.
