Idatius, Idacius or Ithacius
Idatius, Idacius or Ithacius, not to mention sundry other variations of the MSS., a native of Limica, in Gallicia, flourished during the latter half of the fifth century, was in all probability an ecclesiastic, and is known to us as the author of a Chronicum arranged according to the succession of emperors, which commences A. D. 379, the point where Hieronymus breaks off, and extends down to A. D. 469, thus embracing a period of ninety years. In addition to the mere enumeration of names and dates, a short account of the principal occurrences is inserted, referring chiefly to Spanish affairs, and from A. D. 427 Idatius advances his own personal testimony to the truth of the events recorded. He seems to have executed his task with much care, and although a few errors have been detected here and there, the compilation must be regarded as a valuable repertory of naked historical facts.
The greater portion of this Chronicle was printed in the Antiquae
Lectiones of Canisius, 1601, and in the first edition of the Thesaurus Temporum
of J. J. Scaliger, fol. Lug. Bat. 1606, but it was first published in a complete
form, from an ancient MS., by Sirmond, Paris, 1619 (Opera, fol. Venet. 1728, vol.
ii. p. 228), and will be found in the second edition of Scaliger's Thesaurus,
fol. Amst. 1658; in the Bibliotheca Max. Patr. Lug. Bat. 1677, vol. vii. p. 123;
in the Bibliotheca Patrum of Galland, vol. x. p. 323; in the Vett. Lat. Script.
Chron. of Roncalli, Patav. 1787; and in the Chronica Medii Aevi of Roesler, Tubing.
Sirmond found in his MS. immediately after the Chronicum a set of
fasti, exhibiting a complete catalogue of the Roman consuls from the institution
of the office, in the year of the city 245, down to A. D. 468. together with a
few notices of the most remarkable transactions of the fourth and fifth centuries--a
production which, from some resemblance in style, he supposed to belong also to
Idatius; butt this conclusion, although acquiesced in by Roncalli, is not generally
These Fasti Consulares, Descriptio Consulum, or Fasti Idatiani, were
first published by Sirmond along with the Chronicle, but in a more perfect shape
by Labbe, in his Nova Bibliotheca MSS. fol. Paris, 1658, and will be found in
the Bibliotheca Max. Patrum, in the Bibliotheca Patrum, of Galland, in the Venice
edition of Sirmond, in Roncalli, and in Roesler, as referred to above, and also
in Thesaurus Antiquitatum Romanarum of Graevius, vol. xi. p. 246. (See the dissertations
of Roncalli and of Roesler, of which the substance is given by BΓ¤hr. Geschichte
der Rom. Litterat. Suppl. Band. 45).
