The walls are abundantly decorated with paintings, one of a liturgical character.
This was the origin of the principal liturgical vestment, the chasuble (q.v.).
The adoption of the Roman liturgical dress had, however, at most an indirect connexion with these claims. Charlemagne was active in prescribing the adoption of the Roman use; but this was only as part of his general policy in the organization of his em pire.
By this time, moreover, the liturgical character of the vestments was so completely established that they were no longer worn instead of, but over, the ordinary dress.
If Spain and Gaul borrowed from Rome, they also exercised a reciprocal influence on the Roman use; it is interesting to note in this connexion, that of the names of the liturgical vestments a very large proportion are not of Roman origin, and that the non-Roman names tended to supersede the Roman in Rome itself.'
