Reading 36: On Maundy (Mandatum)
On the first four Saturdays of Lent and on Maundy Thursday we perform a Maundy, unless on these Saturdays there be a feast of nine lessons. When the prior sees the hour as being suitable, he shall strike the cymbal once. Then all brothers, in whatever place they are, unless they are sick, ought to prepare themselves and gather together. The almoner ought to provide and prepare warm water, basins, and linen cloths for feet and hands. Then on these Saturdays the septimanarii [weekly attendants] shall perform the Maundy of the respective week. When the prior strikes the cymbal once a second time, the priest and the deacon in their vestments, with the juniors carrying two burning candles before them, ought to come into the chapter room in order and find all brothers ready at their seats. Then all rise and, with everyone bowing, the abbot shall begin the Confiteor (Apostles' Creed) or, if he is away - the priest, standing in the middle of the chapter-room and afterwards he shall say the prayers and orations that follow, while the feet of the brothers are washed. They shall draw up their clothes with their hands modestly so that only the feet appear uncovered. After they have washed their feet, just the same they shall dry them properly.
It should be known besides that on every day of the year except on Maundy Thursday, Maundy ought to be performed for three poor people, on one day for three clerics, on another day for three laymen, which people the almoner ought to provide. To each of them is given one conventual bread and one vegetable dish, such as the community has, and two prebends (allowance portions) of general sort, and two of wine are divided among them. The weekly priest of the morning mass and the subdeacon of the same mass perform this Maundy immediately after the Gospel reading of the high Mass. They go to the alms-house and themselves humbly pour water on the hands of the paupers ready for the Maundy. Then they bless (the food) set for the paupers; the blessing done, going back into the chapter room, they say Verba mea and Miserere mei , and thus finish the thanksgiving. This Maundy is done in the morning and not evening according to ancient custom.
