"Dr. Richard Lucas was the son of Richard Lucas of Presteigne, in Radnorshire, and born in that county about the year 1648.  After a proper foundation at school, he was sent in 1664, to Jesus College, Oxford, where, after taking both his degrees in Arts, at the regular times, he entered into holy orders about the year 1672, and was for some time master of the free school at Abergavenny; but being much esteemed for his talents in the pulpet, he was chosen vicar of St. Stephen’s, Coleman-street, London, and lecturer of St Olave, in Southwark, in 1683.  In 1691, he took the degree of Doctor in Divinity, and was installed prebendary of Westminister in 1696.  His sight began to fail him in his youth, but he lost it totally about this time, and lived many years after this misfortune.  He died on the 29^th of June, 1715, and was buried in Westminister Abbey, but there is no stone or monument there to point out the place of his interment.
It is somewhat remarkable that so few particulars should have been preserved of the life and character of divine of such distinguished merit.  We are only told in general that he was greatly esteemed for his piety and learning; and indeed that he was a most excellent man may be justly inferred from his writings, which are exceedingly valuable, and will preserve his fame to late posterity.  His principal performance is, “ An Inquiry after Happiness,” in tow volumes, octavo, which has passed through several editions, and is justly help in high estimation.  He also published, 1^st, “Practical Christianity, or an Account of the Holiness which the Gospel enjoins, and the Remedies it proposes against Temptations, “ 8vo. 2d, “The Morality of the Gospel” 3d, “ Christian Thoughts for every Day in the Weeks.” 4^th, “A Guide to Heaven.” 5^th, “ The Duty of Servants.” 6^th, Several Sermons, in five volumes, some of which were published by his son, who was of his own name, and survived him, and who was bred at Sidney College, Cambridge, where he took his Master of Arts degree.  Dr. Lucas also translated into Latin the Whole Duty of Man, which was published in 1680, in 8vo.
