With the recent increase in liturgical studies, one rejoices that important source material, such as Durandus' monumental opus, would be made available in English to those unable to work with the original Latin text. From the its title and pre-publication information, one would expect this particular volume to be a translation of the entire Rationale Divinorum Officiorum. Sadly this is not the case: it is merely a reprinting of earlier translations of Books I (J.M. Neale and B. Webb, The Symbolism of Churches and Church Ornaments), III (T.H. Passmore, The Sacred Vestments)and a recent translation of minimal parts of Book IV (R. Coomaraswamy, The Mass). Therefore this volume is a great disappointment, particularly as the chapters dealing with the Mass only go as far as the Blessing of the Incense after the Prayers at the foot of the Altar--essentially ending the dicussion before the Mass has really begun. On a positive note, the illustrations are helpful in adding a bit of colour to the text. One hopes that this taste of the Rationale will result in a cry for an illustrated edition of an English translation of the entire work.
