RITE AND RITUAL
Set against a gold background, a priest elevates a Eucharistic host within an initial C marking the beginning of the Feast of Corpus Christi. Behind him stand a deacon and a subdeacon holding a paten (plate). As this Mass celebrates the real presence of Christ in the Eucharistic offering, the most prominent detail is the monstrance (receptacle) at the corner of the altar, displaying a consecrated host. Unusually for a Mass book, the bottom margin is filled with animal scenes humorously depicting a world upside down. This missal was painted by Master Bertram, a well-documented artist in Hamburg whose workshop also produced panel paintings, sculpture, and decorative arts.
