This large three-volume set of 3000 pages presents liturgical documents (Hudra, Kashkul, and Gaza) for the use of the Chaldean Church. The first volume covers the Annunciation to the Great Fast (Lent), the second Great Fast to Pentecost, and the third Pentecost to the Dedication of the Church. The entire book is only in Syriac, fully vocalized and given in the East Syriac script. An essential resource for studying liturgy in the east, these three volumes will be a welcome addition to any library for students of Syriac, eastern Christianity, and liturgy.
