For the translator of Hilary has before him a very difficult task. It has not been with this as with other volumes of the series, where an excellent translation already existed and careful revision was all that was needed. A small beginning had been made for the De Trinitate by the late Dr. Short, Bishop of Adelaide, whose manuscript was kindly lent to one of the contributors to this volume. But with this exception no English translation of Hilary’s works has been hitherto attempted. That which is now offered is the first in the field. And it must be confessed that Hilary is a formidable writer. I do not think that I know any Latin writer so formidable, unless it is Victorinus Afer, or Tertullian. And the terse, vigorous, incisive sentences of Tertullian, when once the obscurities of meaning have been mastered, run more easily into English than the involved and overloaded periods of Hilary. It is true that in a period of decline Hilary preserves more than most of his contemporaries of the tradition of Roman culture; but it is the culture of the rhetorical schools at almost the extreme point of their artificiality and mannerism. Hilary was too sincere a man and too thoroughly in earnest to be essentially mannered or artificial; but his training had taken too strong a hold upon him to allow him to express his thought with ease and simplicity. And his very merits all tended in the same direction. He has the copia verborum; he has the weight and force of character which naturally goes with a certain amplitude of style; he has the seriousness and depth of conviction which keeps him at a high level of dignity and gravity but is unrelieved by lighter touches.
