By the influence of the same imperial Edict, not only _Spain_ and _Gallia_, but also _Illyricum_ became subject to the Pope. _Damasus_ made _Ascholius_, or _Acholius_, Bishop of _Thessalonica_ the Metropolis of _Oriental Illyricum_, his Vicar for hearing of causes; and in the year 382, _Acholius_ being summoned by Pope _Damasus_, came to a Council at _Rome_. Pope _Siricius_ the successor of _Damasus_, decreed that no Bishop should be ordained in _Illyricum_ without the consent of _Anysius_ the successor of _Acholius_. And the following Popes gave _Rufus_ the successor of _Anysius_, a power of calling Provincial Councils: for in the Collections of _Holstenius_ there is an account of a Council of _Rome_ convened under Pope _Boniface_ II. in which were produced Letters of _Damasus_, _Syricius_, _Innocent_ I. _Boniface_ I. and _Caelestine_ Bishops of _Rome_, to _Ascholius_, _Anysius_ and _Rufus_, Bishops of _Thessalonica_: in which Letters they commend to them the hearing of causes in _Illyricum_, granted by the Lord and the holy Canons to the Apostolic See thro'out that Province. And Pope _Siricius_ saith in his Epistle to _Anysius_: _Etiam dudum, frater charissime, per Candidianum Episcopum, qui nos praecessit ad Dominum, hujusmodi literas dederamus, ut nulla licentia esset, sine consensu tuo in Illyrico Episcopos ordinare praesumere, quae utrum ad te pervenerint scire non potui. Multa enim gesta sunt per contentionem ab Episcopis in ordinationibus faciendis, quod tua melius caritas novit_. And a little after: _Ad omnem enim hujusmodi audaciam comprimendam vigilare debet instantia tua, Spiritu in te Sancto fervente: ut vel ipse, si potes, vel quos judicaveris Episcopos idoneos, cum literis dirigas, dato consensu qui possit, in ejus locum qui defunctus vel depositus fuerit, Catholicum Episcopum vita & moribus probatum, secundum Nicaenae Synodi statuta vel Ecclesiae Romanae, Clericum de Clero meritum ordinare_. And Pope _Innocent_ I. saith in his Epistle to _Anysius_: _Cui_ [Anysio] _etiam anteriores tanti ac tales viri praedecessores mei Episcopi, id est, sanctae memoriae Damasus, Siricius, atque supra memoratus vir ita detulerunt; ut omnia quae in omnibus illis partibus gererentur, Sanctitati tuae, quae plena justitiae est, traderent cognoscenda_. And in his Epistle to _Rufus_ the successor of _Anysius_: _Ita longis intervallis disterminatis a me ecclesiis discat consulendum; ut prudentiae gravitatique tuae committendam curam causasque, siquae exoriantur, per Achaiae, Thessaliae, Epiri veteris, Epiri novae, & Cretae, Daciae mediterraneae, Daciae ripensis, Moesiae, Dardaniae, & Praevali ecclesias, Christo Domino annuente, censeam. Vere enim ejus sacratissimis monitis lectissimae sinceritatis tuae providentiae & virtuti hanc injungimus sollicitudinem: non primitus haec statuentes, sed Praecessores nostros Apostolicos imitati, qui beatissimis Acholio & Anysio injungi pro meritis ista voluerunt_. And _Boniface_ I.
