This little booklet based on Father Adrian Fortescue's famous work, The Mass: A Study of the Roman Liturgy, provides a compact history of the Roman Rite of the Mass from the Last Supper to the Traditional Mass ('Tridentine Mass') as it is said today. The reader will gain an appreciation of our sacred liturgical heritage - passed down to us from Christian antiquity and intended to be passed on to all Catholic generations yet to come.
