In the preface to Night Thoughts Young states that the occasion of the poem was real, and Philander and Narcissa have been rather rashly identified with Mr and Mrs Temple. It has also been suggested that Philander represents Thomas Tickell, an old friend of Young's, who died three months after Lady Elizabeth Young. The infidel Lorenzo was thought by some to be a Sketch of Young's own son, but he was only eight years old at the time of publication. The Complaint, or Night Thoughts on Life, Death and Immortality, was published in 1742, and was followed by other "Nights," the eighth and ninth appearing in 1745. In 1753 his tragedy of The Brothers, written many years before, but suppressed because he was about to enter the Church, was produced at Drury Lane. Night Thoughts had made him famous, but he lived in almost uninterrupted retirement. He was made clerk of the closet to the Princess Dowager, Augusta of Saxe-Gotha, in 1761. He never recovered from his wife's death. He fell out with his son, who had apparently criticised the excessive influence exerted by his housekeeper Mrs Hallows. The old man refused to see his son until shortly before he died, but left him everything. A description of him is to be found in the letters of his curate and executor, John Jones, to Dr Thomas Birch (in Brit. Lib. Addit. M/s 4311). He died at Welwyn, reconciled with his spendthrift son: "he expired a little before 11 of the clock at the night of Good Friday last, the 5th instant, and was decently buried yesterday about 6 in the afternoon" (Jones to Birch).
