On 1 June 1318, immediately after his installation as Bishop of Alet, Barthélemy was sent by Pope John XXII to Lithuania, to evangelize King Gedeminnus, at the king's request. In 1319 he sat as an assessor on the bench of bishops who tried Bernard Delicieux. Barthélemy is last heard of in 1329. Edmond Martène; Ursin Durand (1717). Thesaurus novus anecdotorum (in Latin).

In the election following the death of Bishop Guillaume de Rupe, the Chapter elected Jean Dupuy and he was confirmed by the Metropolitan; he then refused the election. The Chapter then elected Pierre Raymond. But Dupuy reconsidered, and wanted to be confirmed as bishop. His desire was opposed by the King, who prevailed upon Pope Julius II to confirm Pierre Raymond, which the Pope did, on 7 July 1508. Jean Dupuy never received either the temporalities or the spiritualities of the Diocese of Alet. He maintained his pretensions until 1511, when he had to resign them in order to have his election to a new term as Abbot of Saint-Tibéry confirmed by the Papacy.

Antonius Dax (d'Acqs) was one of three brothers, sons of Jean Dax, Seigneur de Leuc, de la Serpente, du Lion, d'Axat, et d'Argibues. Antoine had been a Canon and Precentor of the Cathedral Chapter, and was Abbot of Saint-Polycarpe (diocese of Narbonne) from 1529 to 1565. He served as Grand Vicar for Cardinal Charles de Bourbon-Vendôme, who was Bishop of Carcassonne 1546-1552. He was elected Bishop of Alet on 26 September 1564, and confirmed on 8 June 1565 by Pope Pius IV. Lasserre, p. 142, states that Dax died in 1572, and that, due to the Huguenots having destroyed the cathedral and driven off the Canons, an election could not be held for some time. Eubel, III, p. 193 note 11, points out that he was already a septuagenarian when appointed to the diocese of Alet on 8 June 1565, and that a successor was not appointed until 1594, there must have been a long sede vacante.
