OGLERIO of Trino, Blessed. — Cistercian abbot, d. 10 Sept. 1214. From c. 1205 until his death he was abbot of the monastery of St Mary of Lucedio near Trino Vercellese. His cult from time immemorial was confirmed by Pius IX on 18 Apr. 1875.
The 13th-century codex of Staffarda (Turin, University Library: E. V. 4; Lat. 761) ascribes to him the *Tractatus in laudibus s. Dei Gemitricis*, a collection of sermons addressed to religious, composed before 1206, and the *Expositio super Evangelium in Coena Domini* in 13 homilies, written after he became abbot for his monks; in the oldest editions of Bernardine works the latter was attributed to St Bernard. The same holds for the sermon *Quis dabit* from the *Tractatus* (G. B. Adriani [q.V. bibliography], pp. 80–90), published under the title *Tractatus b. Bernardi de lamentatione V. Mariae* (cf. E. De Levis, *Anecdota sacra*, Turin 1789, pp. 60–99).
His religious ideas and exposition, replete with biblical phrases and liturgical reminiscences, often in the form of a moving and urgent dialogue, are inspired by the ascetic climate and language of the Bernardine and Cistercian works of the period; yet O. regarding the Immaculate Conception in the *Expositio* (G. B. Adriani, p. 226) departs from the negative opinion of St Bernard, previously followed (Tractatus, in G. B. Adriani, p. 3), with a vigorous affirmation of this singular privilege of Mary.
OGLIASTRA, DIOCESE OF. — In the province of Nuoro with the episcopal see at Lanusei.
It has an area of 2,461 sq km and a population of 55,000 all Catholic, distributed in 28 parishes served by 49 diocesan and 8 regular priests; it has a seminary, 1 male and 8 female religious communities (Ann. Pont. 1952, p. 299).
In the Middle Ages this eastern region of Sardinia was called Barbagia or Barbaria, a name also given to a diocese corresponding to this territory. The diocese was erected by Pope Leo XII on 11 Nov. 1824 by dividing the archdiocese of Cagliari, at the request of Charles Felix I, King of Sardinia, as a suffragan of Cagliari, as it remains today. The first bishop was Msgr Serafino Carchero, later translated to Bisarchio in 1834.
