This edition makes available for the first time a previously
lost work of Thomas Aquinas.
Ptolomeo of Lucca, the friend, confessor, and biographer of
Aquinas, uniquely reported that Thomas, while in Rome, has written
a second commentary on Book I of Peter Lombard's Liber
sententiarum. The Lectura romana is that commentary.
It is a reportatio of Aquinas's lectures on Peter Lombard
given in Rome in 1265-66. An entirely new commentary, the
Lectura romana contains a prologue, ninety-seven articles
covering distinctions 1-17 and 23, and three short notes on
distinctions 3 and 24. These lectures cover the nature of sacra
doctrina, the names and attributes of God, the Trinity, and
The Roman Province of the Order of Preachers has established a
new studium at Rome in which Thomas would teach his fellow
Dominicans beginning their theological education. The Lectura
romana constituted only part of his teaching in this new
studium. In this work, we have the only surviving
reportatio of Thomas's teaching other than biblical
commentaries. Because it can be precisely dated to 1265-66, it is
also particularly promising for understanding the development of
Aquinas's thought on a number of central theological topics.
Written with the trim precision of the Summa theologiae,
the Lectura romana contains questions, arguments, and
examples not found elsewhere in the works of Aquinas.
The Lectura romana survives in the margins and guard
folia of a thirteenth-century manuscript of the Parisian
Scriptum now in Lincoln College, Oxford.
