Venite adoremus deum et procidamus ante

The rubric is at the right bottom corner of 117v. The initial and the chant is in 118v. Contrary to other sources in the irregular mode of Alamire, this source is in the regular Dsolre, with the beginning formula ("alevantar") "Venite" recomposed in order to more easily define the mode; also at "et procidamus" the plagal diathesaron is clarified.
