THOMAS A KEMPIS (c. 138o-1471), the name by which the Augustinian canon and writer Thomas Hammerken (Hammer chen, Malleolus) is commonly known. He was born in 1379 or 138o in the town of Kempen, near Diisseldorf, in one of the many patches of territory between the Meuse and the Rhine belonging to the archiepiscopal principality of Cologne. "Ego Thomas Kempis," he says in his chronicle of the monastery of Mount St. Agnes, "scholaris Daventriensis, ex diocesi Coloniensi natus." His father was a poor hard-worked peasant ; his mother "ad cus todiam rei domesticae attenta, in opere alacris, in victu sobria, in potu abstemia, in verbo pauca, in factis pudica," as her son fondly says, kept a dame's school for the younger children of the town. John and Gertrude Hammerken had two sons, John and Thomas, both of whom found their way to Deventer, and thence to Zwolle and to the convent of Mount St. Agnes. Thomas reached Deventer when he was barely twelve years old, was taught by a dame the beginnings of his learning, and in a few months to his great joy entered the classes of Florentius Radewyn. After the fashion of the time he was called Thomas from Kempen, and the school title, as was often the case then, pushed aside the family name. Thomas Hammerken was forgotten ; Thomas a Kempis has be come known to the whole Christian world.
The school at Deventer had become famous long before Thomas a Kempis was admitted to its classes. It had been founded by Gerhard Groot (q.v.), a wealthy burgher who had been won to pious living mainly through the influence of Ruysbroeck, the Flemish mystic. At Deventer, in the midst of this mystical theology and hearty practical benevolence, Thomas a Kempis was trained. Gerhard Groot was his saintly ideal. Florentius Radewyn and Gerhard's other early disciples were his heroes; their presence was his atmosphere, the measure of their lives his horizon. But he was not like them; he was not an educational reformer like Radewyn, nor a man of affairs like Gerhard. He liked books and quiet corners all his days, he says; and so, when conviction of sin and visions of God's grace came to him in the mediaeval fashion of a dream of the anger and forgiveness of the Virgin, Florentius told him that a monk's life would suit him best, advised him to join the Augustinian order, and sent him to Zwolle to the new convent of Mount St. Agnes, where his brother John was prior. Thomas was received there in 1399, professed the vows in 1407, received priest's orders in 1413, became sub-prior in 1425 and died on Aug. 8, 1471, at the age of ninety-one.
Works.—The convent of Mount St. Agnes was poor, and most of the monks had to earn money to support their household by copying MSS. Thomas was a most laborious copyist ; missals, books of devotion and a famous MS. Bible were written by him.
He also wrote a large number of original writings, most of them relating to the convent life, which was the only life he knew.
He wrote a chronicle of the monastery and several biographies— the life of Gerhard Groot, of Florentius Radewyn, of a Flemish lady St. Louise, of Groot's original disciples ; a number of tracts on the monastic life—The Monk's Alphabet, The Discipline of Cloisters, A Dialogue of Novices, The Life of the Good Monk, The Monk's Epitaph, Sermons to Novices, Sermons to Monks, The Solitary Life, On Silence, On Poverty, Humility and Patience; two tracts for young people—A Manual of Doctrine for the Young, and A Manual for Children; and books for edification— On True Compunction, The Garden of Roses, The Valley of Lilies, The Consolation of the Poor and the Sick, The Faithful Dispenser, The Soul's Soliloquy, The Hospital of the Poor. He also left behind him three collections of sermons, a number of letters, some hymns and the famous Imitatio Christi (though his authorship of this has been disputed).
Character.—These writings help us to see the man and his surroundings, and contemporary pious records make him some thing more than a shadow. We see a real man, but a man helpless anywhere save in the study or in the convent—a little fresh coloured man, with soft brown eyes, who had a habit of stealing away to his cubiculum whenever the conversation became too lively ; somewhat bent, for it is on record that he stood upright when the psalms were chanted, and even rose on his tiptoes with his face turned upwards; genial, if shy, and occasionally given to punning, as when he said that he preferred Psalmi to Salmones; a man who perhaps led the most placid uneventful life of all men who ever wrote a book or scribbled letters. His brethren made him oeconomiae prefectus, but he was too "simple in worldly affairs" and too absent-minded for the post, and so they deposed him and made him sub-prior once more. And yet it is this placid kindly fresh-coloured old man who has come down to us as the author of that book the Imitation of Christ, which has been translated into more languages than any other book save the Bible, and which has moved the hearts of so many men.
On the controversy as to the author of the Imitatio, see the article IMITATION OF CHRIST. See also James Williams, Thomas of Kempen (191o). The classical edition of the works of Thomas it Kempis by Sommalius—Thomas Malleoli a Kempis opera omnia (3 vols. in 1, i607)—has been many times reprinted. A critical edition in 8 vols. by M. J. Pohl has also been undertaken. The best accounts in Eng lish of Thomas a Kempis are those by S. Kettlewell (1882) and F. R. Cruise (1887), written from the Protestant and the Catholic stand points respectively. A penny tract by F. R. Cruise, entitled Outline of the Life of Thomas a Kempis (19o4), contains substantially all that is known concerning him. (T. M. Li.)
