Obedientiaries, the plural of Obedienciary, from the Latin Obedientiarius, meaning someone in an 'obedient', i.e. subordinate, position, is a term commonly used in medieval times for the lesser officials of a monastery who were appointed by will of the superior.
In some cases the word is used to include all those who held office beneath the abbot, but more frequently the prior and sub-prior -who technically qualify in an abbacy- are excluded from those signified by it.
To the obedientiaries were assigned the various duties pertaining to their different offices and they possessed considerable power in their own departments. There was always a right of appeal to the abbot or equivalent superior, but in practice most details were settled by the "customary" of the monastery.
The list that follows gives the usual titles of the obedientiaries, but in some monasteries other names were used and other official positions may be found: thus, for example, to this day, in the great Swiss monastery of Einsiedeln the name "dean" is given to the official who is called prior in all other Benedictine houses.
(1) The "cantor" or "precentor", usually assisted by a "sub-cantor", or "succentor".

(3) The cellarer, or bursar, who acted as chief purveyor of all foodstuffs to the monastery and as general steward. In recent times the name is often found used for this official. He had as assistants:
(4) The refectorian, who had charge of the frater or refectory and its furniture, including such things as crockery, cloths, dishes, spoons, forks etc.

(6) The novice master whose assistant was sometimes called the "zelator".
