Aliyah la-Regel

The three pilgrim festivals were agricultural before they were anything else. Pesach falls at the barley harvest, Shavuot at the wheat harvest seven weeks later, and Sukkot at the ingathering of fruit at the end of the season, and each carries an offering appropriate to what has just been brought in. Centralising sacrifice in Jerusalem took that farming calendar and attached it to a single building, so that three times a year the population of a largely rural country was required to travel to one city and appear there.

E. P. Sanders's study of Jewish practice in the late Second Temple period works out what that meant in operation: the logistics of moving animals for sacrifice, the tithes that had to be brought or converted into money and spent in the city, the accommodation problem, and the priestly courses that rotated through service.

The commandment as stated in Deuteronomy applies to men and says that no one should appear empty handed, with the offering scaled to means. In practice whole households travelled, and the festivals were the occasions on which a dispersed people saw itself assembled. That experience, rather than the sacrifice itself, is what much of the later literature remembers about them.

The pilgrimage ended in 70 CE, when Roman forces destroyed the Second Temple and the altar, the sacrificial service and the destination of the journey ceased together. Josephus, who witnessed the war and wrote about it for a Roman readership, describes the crowds the festivals had drawn and the conditions inside the besieged city at Passover, and his figures for the numbers present are large enough that historians treat them with caution while accepting the general picture of a city that filled beyond its capacity. What followed is one of the most consequential adaptations in religious history.

Rabbinic Judaism kept the three festivals as observances of the calendar and detached them from the journey, transferring the weight of the occasion to the household table and the synagogue. Pesach became a meal conducted at home with a fixed order and a text; Shavuot became associated with the giving of the Torah and with study; Sukkot kept its booth. Prayer at fixed hours took the place of the daily offerings. The atlas therefore catalogues aliyah la-regel as a historical institution rather than a living pilgrimage, while noting that the impulse behind it did not disappear and reappeared in later visitation to the Temple's surviving wall.
