A vast material of ordines for Maundy Thursday and Good Friday has recently been made available on our website. Besides the basic contents of the Mass and the Mass of the Presanctified, evidence for the consecration of Chrism, the washing of the feet, and the peculiarities of Good Friday (solemn intercessions, adoration of the cross, communion, repose) can be studied. The sample relies both on the testimony of printed Missals and Rituals and that of ancient Sacramentaries and Pontificals.
