Early Medieval Prose Liturgy

The Crystallization of the Jewish Prayer Service 

Even given numerous local variations, a common fixed liturgy has existed for many centuries. But this was not always the case. While the main structural elements are presumed to have been composed during the talmudic period, neither the Jerusalem (Palestinian) nor the Babylonian Talmud contains the actual wording of the statutory prayers. Written evidence for most of the Jewish prayer service appears only in the early medieval period, beginning around the ninth century, and much of the shape of the early liturgy remains a matter of speculation.

Thus, for example, the existence of the Amidah (standing prayer) is well attested by the time of the codification of the Mishnah (ca. 200 CE), but the precise wording of the benedictions, apart from the opening and closing formulas, was not yet stable. The Mishnah itself does not clearly address the prayer’s origins. 

In this respect, there is an intriguing gap between the last books of the biblical canon (which do not mention fixed prayer at all) and the beginning of the tannaitic tradition. 

During the early medieval period, the basic outline of the Rabbanite service—and, eventually, the standardized prayers themselves—was committed to writing for the first time, the liturgy crystallized into the complex structure that we know today, and the first prayer books came into being.

Different Types of Prayer Texts

A diverse array of prayer texts appear in this period, often in alternative versions or as seen for the first time in writing. Some are now-familiar prayers that were innovations of this period, such as Av ha-raḥamim (Father of Mercy). Others are prayers that predate our period—likely composed during the talmudic period—but that appear in interesting variant versions. Yet others are prayers that later fell out of favor, such as a new husband’s blessing over the signs of virginity in his bride, or that were written for specific historical circumstances, such as a prayer for the health and well-being of the Fātimid caliph.
