The Asturica Augusta of the Romans was the capital of the northern provinces of Asturias and the central point of four military roads which led to Braga, Aquitania, Saragosse, and Tarragon.
During the Visigothic domination, and especially under the reign of Witiza, Astorga as well as Leon, Toledo, and Tuy were the only four cities allowed to retain their walls.
According to some accounts, Astorga was the seat of the earliest bishopric in the peninsula, having been consecrated in the first century by Santiago or his immediate followers; historically, however, the first known bishop was Dominiciano, who lived about 347 A. D.
In the fourth and fifth centuries several heresies or false doctrines were ripe in Spain. Of one of these, Libelatism, Astorga was the centre; the other, Priscilianism, originally[{168}] Galician, found many adherents in the fortress-town, more so than elsewhere, excepting only Tuy, Orense, and Palencia.
Libelatism.—Its great defender was Basilides, Bishop of Astorga. Strictly speaking, this faith was no heresy, but a sham or fraud which spread out beyond the Pyrenees to France. It consisted in denying the new faith; those who proclaimed it, or, in other words, the Christians, who were severely persecuted in those days, pretended to worship the Latin gods so as to save their skins. With this object in view, and to be able to prove their sincerity, they were obliged to obtain a certificate, libelum (libel?), from the Roman governor, stating their belief in Jupiter, Venus, etc. Doubtless they had to pay a tax for this certificate, and thus the Roman state showed its practical wisdom: it was paid by cowards for being tyrannical. But then, not all Christians are born martyrs.
Priscilianism.—Of quite a different character was the other heresy previously mentioned. It was a doctrine opposed to the Christian religion, proud of many adherents, and at one time threatening danger to the Holy Roman Catholic Church. Considering[{169}] that it is but little known to-day (for after a lingering life of about three or four centuries in Galicia it was quite ignored by philosophers and Christians alike), it may be of some use to transcribe the salient points of this doctrine, in case some one be inclined to baptize him or herself as prophet of the new religion. It was preached by one Prisciliano in the fourth century, and was a mixture of Celtic mythology and Christian faith.
"Prisciliano did not believe in the mystery of the Holy Trinity; he believed that the world had been created by the devil (perhaps he was not wrong!) and that the devil held it beneath his sway; further, that the soul is part of the Divine Essence and the body dependent upon the stars; that this life is a punishment, as only sinful souls descend on earth to be incarnated in organic bodies. He denied the resurrection of the flesh and the authenticity of the Old Testament. He defended the transmigration of souls, the invocation of the dead, and other ideas, doubtless taken from native Galician mythology. To conclude, he celebrated the Holy Communion with grape and milk instead of with wine, and admitted that all true believers[{170}] (his true believers, I suppose, for we are all of us true believers of some sort) could celebrate religious ceremonies without being ordained curates."
Sinfosio, Bishop of Astorga in 400, was converted to the new religion. But, upon intimation that he might be deprived of his see, he hurriedly turned Christian again, putting thus a full stop to the spread of heresy, by his brave and unselfish act.
Toribio in 447 was, however, the bishop who wrought the greatest harm to Priscilianism. He seems to have been the divine instrument called upon to prove by marvellous happenings the true religion: he converted the King of the Suevos in Orense by miraculously curing his son; when surrounded by flames he emerged unharmed; when he left his diocese, and until his return, the crops were all lost; upon his return the church-bells rang without human help, etc., etc. All of which doings proved the authenticity of the true religion beyond a doubt, and that Toribio was a saint; the Pope canonized him.
During the Arab invasion, Astorga, being a frontier town, suffered more than most cities farther north; it was continually being[{171}] taken and lost, built up and torn down by the Christians and Moors.
