THE "SUMMA THEOLOGICA"

xxxiv THE "SUMMA THEOLOGICA"
confided to Cardinal de Luca, Cardinal Simeoni, and Cardinal
Zigliara. With the works of St. Thomas they were directed
to edit Cajetan on the' Summa Theologica,' and Ferraxiensis
on the ' Contra Gentiles.'
Cardinal ZigIiara, in the Preface to the first Volume, says
that, in obedience to the command of His Holiness,' Magister
Generalis Ordinis Prmdicatorum cui demandata est a
Leone XlII., cura hujus editionis operum Sti. Thomm,
quosdarn religiosos in scientiis simul et arte paleographica
eruditos designavit, qui bibliothecas perlustrant, codices
optimm norm inquirunt, scripta S. Thomm inedita diligenter
investigant, atque omnia scripta notata aliis religiosis
Romm degentibus et novarn hanc editionem curantibus
transmittant.'
The groundwork of the new edition is that of St. Pius V.
(I57o). Little is known of the history of this edition.
Several learned Dominicans were employed in it, and
among them Remigius Narmi, Cardinal Justiniani, and
Thomas Marriques, S.P.A. Magister. It is the best of all
the editions of the ' Opera Omnia' published up to the time
of Leo XIII. As the Pope says in his letter to Cardinal de
Luca : ' Coetera enim, cum veteres turn recentiores, partita
quod non ornnia S. Thomm scripta exhibent, partita quod
optimorum, ejus interpretum atque explanatorum careant
commentariis, partita quod minus diligenter adornat_e sint,
non omnia tulisse puncture videntur.'
This Piana, or Roman, Edition, however, seems to have
been made with the help of earlier editions ra_er than of the
manuscripts.
The first Volume of the Leonine Edition comprises the
' Dissertation of De Rubeis on the Life and Writings of St.
Thomas,' also the 'Commentaries of the Saint on Aristotle's
Works,' ' Peri Hermenias,' and ' Posteriora Analytica.'
As St. Thomas's Commentaries on the former terminate at
the end of the Second Book, Cajetan's Commentary on the
remainder has been given.
The Greek text of Aristotle (Didot's edition) has been
inserted in place of the second Latin version given by the
Piana,synopsesofeachlessonand copiousnotesbeingadded.
