Henry Vaughan (17 April 1621 – 23 April 1695) was a Welsh metaphysical poet, author, translator and physician, who wrote in English. He is chiefly known for the religious poetry contained in Silex Scintillans, published in 1650, with a second part published in 1655. In 1646 his poems, with the Tenth Satyre of Juvenal Englished, were published, followed by a second volume in 1647. Meanwhile, he had been “converted” by reading the religious poet George Herbert and gave up “idle verse”. The prose Mount of Olives: or, Solitary Devotions (1652) show the depth of his religious convictions and the authenticity of his poetic genius. Two more volumes of secular verse followed, ostensibly without his sanction, but it is his religious verse that has become acclaimed. He also translated short moral and religious works and two medical works in prose. At some time in the 1650s he began to practise medicine and continued to do so through his life.
