Anton Baumstark notes that much of the information concerning the holy sites of Jerusalem in the early centuries of Christianity comes from the accounts of various pilgrims such as Egeria. However, Baumstark argues that there are other sources that should be utilized in descriptions of Jerusalem in the Byzantine era. In the present article, Baumstark describes one such source, namely, a Typikon containing an Easter and Holy Week Rite. Throughout the article, Baumstark compares the description of holy sites—particularly those related to the Holy Sepulcher—to the descriptions found in other texts and to insights from modern archaeology. Based on this comparison with other accounts, Baumstark dates the description to the middle of the tenth century. The description makes a valuable contribution to our understanding of the layout of various holy sites in Jerusalem in the Byzantine era.
