The translation is intended, then, to be faithful and exact, but it deliberately avoids any attempt to treat the language of Vitruvius as though it were Ciceronian, or to give a false impression of conspicuous literary merit in a work which is destitute of that quality.

The translator had, however, the utmost confidence in the sincerity of Vitruvius and in the serious purpose of his treatise on architecture.
To those who have liberally given their advice and suggestions in response to requests from Professor Morgan, it is impossible for me to make adequate acknowledgment.

Their number is so great, and my knowledge of the indebtedness in individual cases is so small, that each must be content with the thought of the full and generous acknowledgment which he would have received had Professor Morgan himself written this preface.
Personally I am under the greatest obligations to Professor H.L.
Warren, who has freely given both assistance and criticism; to Professor G.L.Kittredge, who has read with me most of the proof; to the Syndics of the Harvard University Press, who have made possible the publication of the work; and to the members of the Visiting Committee of the Department of the Classics and the classmates of Professor Morgan, who have generously supplied the necessary funds for the illustrations.
