Aurea luce (v.1) and Doctor egregie Paule (v.4) are attributed with certainty to Dufay
V-CVbav-ms-Capp.Sist.15: [US-U, Renaissance Archives, VatS 15] numbers this verse as v.4, and 'Sit trinitati' as v.6; Rism considers this verse as separate hymn; 'Doctor egregie' normally comes before 'Sit trinitati'
