[Do]cente quaedam erroris cultor? Hermoge(...)

The text in this source seems to diverge slightly from the text found in other Portuguese sources. Since the following item is a responsory verse, this chant could be a Responsory instead, but it doesn't exist on Cantus Index. Since this source is such in a bad condition and the text barely readable, I decided not to input a new chant with a new Cantus ID.
