Mr. Lock likewise was so highly satisfied with the Defence, (which was perhaps the only piece that appeared in favour of his Essay, except one by Mr. Samuel Bold, rector of Steeple in Dorsetshire, 1699) that being in London, he desired Mr. King, afterwards lord high chancellor, to make Mrs. Trotter a visit, and a present of books; and when she had owned herself, he wrote to her a letter of compliment, a copy of which is inserted in these memoirs.
But while our author continued to shew the world so deep a penetration into subjects of the most difficult and abstract kind, she was still incapable of extricating herself from those subtilties and perplexities of argument, which retained her in the church of Rome. And the sincerity of her attachment to it, in all its outward severities, obliged her to so strict an observance of its fasts, as proved extremely injurious to her health. Upon which Dr. Denton Nicholas, a very ingenious learned physician of her acquaintance, advised her to abate of those rigours of abstinence, as insupportable to a constitution naturally infirm.
She returned to the exercise of her dramatic genius in 1703, and having fixed upon the Revolution of Sweden under Gustavus Erickson (which has been related in prose with so much force and beauty by the Abbé Vertot) for the subject of a Tragedy, she sent the first draught of it to Mr. Congreve, who returned her an answer, which, on account of the just remarks upon the conduct of the drama, well deserves a place here, did it not exceed our proposed bounds, and therefore we must refer the reader to Dr. Birch's account. This Tragedy was acted in 1706, at the Queen's Theatre in the Hay-Market, and was printed in quarto.
By a letter from Mrs. Trotter to her friend George Burnet of Kemnay in Scotland, Esq; then at Geneva, dated February 2, 1703-4, it appears that she then began to entertain more moderate notions of religion, and to abate of her zeal for the church of Rome. Her charitableness and latitude of sentiments seems to have increased a-pace, from the farther examination which she was now probably making into the state of the controversy between the church of Rome and the Protestants; for in another letter to Mr. Burnet, of August 8, 1704, she speaks to the subject of religion, with a spirit of moderation unusual in the communion of which she still professed herself.
