Hincmar of Reims gave directions as follows: "Every Sunday, before the celebration of Mass, the priest shall bless water in his church, and, for this holy purpose, he shall use a clean and suitable vessel. The people, when entering the church, are to be sprinkled with this water, and those who so desire may carry some away in clean vessels so as to sprinkle their houses, fields, vineyards, and cattle, and the provender with which these last are fed, as also to throw over their own food" ("Capitula synodalia", cap. v, in P.L., CXXV, col, 774).
