The Churches of Gaul, as might naturally be expected, were the first to adopt the devotion. St. Alcimus Avitus, who was one of the earliest successors of St. Mamertus
in the See of Vienne, informs us that the custom of keeping the Rogation days was, at that time, firmly established in his diocese. St. Caesarius of Arles, who lived in the early part of the 6th century, speaks of them as being observed in countries afar off;
by which he meant, at the very least, to designate all that portion of Gaul which was under the Visigoths. That the whole of Gaul soon adopted the custom is evident from the canons drawn up at the first Council of Orleans, held in 511, which represented all
the provinces that were in allegiance to Clovis. The regulations made by the Council regarding the Rogations, give us a great idea of the importance attached to their observance. Not only abstinence from meat, but even fasting, is made of obligation. Masters
are also required to dispense their servants from work, in order that they may assist at the long functions which fill up almost the whole of these three days. In 567 the Council of Tours, likewise imposed the precept of fasting during the Rogation days; and
as to the obligation of resting from servile work, we find it recognized in the Capitularia of St. Karl the Great and Charles the Bald.
