This study explores the first origins of the mass proto-form (5-6 -part Ordinary), the early stages of the formation and evolution of its primary structures. As it is known, the text of the Ordinary (unlike the Proper) is constant and performed throughout the year. A thorough analysis of the mass proto-form revealed an unusual concurrence between a series of numerical parameters of its text and some key astronomical, computus and church calendar data. Such concurrences, particularly when we deal with three-digit numbers, are unlikely to be accidental. Rather, they suggest that the Ordinary had a double or even triple function: externally, it represented an established sequence of sacred texts for the liturgical service; while internally it served as some sort of numerological code containing certain concealed information of the calendar-computus and serving, at the same time, as a mnemonic device used to compute and memorize this information.
