The offertory has played a crucial role in recent vigorous debates about the origins of Gregorian chant. Its elaborate solo verses are among the most splendid of chant melodies, yet the verses ceased to be performed in the twelfth and thirteenth centuries, making them among the least known and studied chants of the repertory. This study draws on the music, lyrics, and liturgical history of the offertory to shed new light on its origins and chronology. The book addresses issues that are at the heart of chant scholarship, such as the relationship between the Gregorian and Old Roman melodies, the nature of oral transmission, the presence of non‐Roman pieces in the Gregorian repertory, and the influence of theoretical thought on the transmission of the melodies. In contrast to the view that the Roman chant versions closely reflect the eighth‐century state of the melodies, this book argues that the prolonged period of oral transmission from the eighth to the eleventh centuries instead enforced a formulaic trend. Demonstrating that certain musical and textual traits of the offertory are distributed in distinct patterns by liturgical season, this study outlines new chronological layers within the repertory and explores the presence and implications of foreign imports into the Roman and Gregorian repertories. Available for the first time as a complete critical edition, ninety‐four Gregorian and Old Roman offertories are presented here in side‐by‐side transcriptions. A companion website provides music examples and essays that elucidate these transcriptions and the variants between manuscripts.
