De Trinitate

''On the Trinity'' ( la, De Trinitate) is a Latin book written by Augustine of Hippo to discuss the Trinity in context of the logos. Although not as well known as some of his other works, some scholars have seen it as his masterpiece, of more doctrinal importance even than '' Confessions'' or ''The City of God''.

It is placed by him in his '' Retractationes'' among the works written (meaning begun) in AD 400. In letters of 410 and 414 and at the end of 415, it is referred to as still unfinished and unpublished. But a letter of 412 states that friends were at that time asking to complete and publish it, and the letter to Aurelius, which was sent with the treatise itself when actually completed, states that a portion of it, while still unrevised and incomplete, was in fact surreptitiously made public. It was still in hand in 416: in Book XIII, a quotation occurs from the 12th Book of the ''De Civitate Dei''; and another quotation in Book XV, from the 99th Tractate on John's Gospel.

The ''Retractationes'', which refer to it, are usually dated not later than 428. The letter to Bishop Aurelius also states that the work was many years in progress and was begun in Saint Augustine's early manhood. It was finished in his old age. Arthur West Haddan inferred from this evidence that it was written between 400, when he was forty-six years old and had been Bishop of Hippo about four years, and 428 at the latest; but it probably had been published ten or twelve years earlier, in or around 417. Translator's Preface

It is also the title of works written by at least two other scholars of the early church: Hilary of Poitiers (the Hammer of the Arians) and Richard of St. Victor.
