This stylised depiction of a priest celebrating Low Mass is rich with the aesthetic ideals of the Liturgical Movement. The celebrant wears a flowing albe, ornamented with continuous decoration around its hem. Over this he is vested in a conical chasuble, decorated very simply. Not least of interest is the manner in which the altar cloth is decorated, with geometric embroideries and tassles of silk.
One curiosity is the almost sleeveless surplice being worn by the altar server. Note the restrained gesture with which he lifts the celebrant's chasuble for the Elevation.
Would that this dignified aesthetic were more fully adopted for the celebration of Mass according to both usages of the Roman Rite.
