The sound of the Voice of Columbkille
Great its sweetness above all clerics:
To the end of fifteen hundred paces,
Though great the distance, it was distinctly heard.
— From the Irish Life of St. Columba in the Leabhar Breac.
I must not pass over another well-authenticated story, told, indeed, by those who heard it, regarding the voice of the blessed man in singing the psalms. The venerable man, when singing in the church with the brethren, raised his voice so wonderfully that it was sometimes heard four furlongs off, that is five hundred paces, and sometimes eight furlongs, that is one thousand paces. But what is stranger still: to those who were with him in the church, his voice did not seem louder than that of others; and yet at the same time persons more than a mile away heard it so distinctly that they could mark each syllable of the verses he was singing, for his voice sounded the same whether far or near. It is however admitted, that this wonderful character in the voice of the blessed man was but rarely observable, and even then it could never happen without the aid of the Holy Ghost.
Nam ipse Sanctus cum paucis fratribus extra regis munitionem dum vespertinales Dei laudes ex more celebraret, quidam Magi, ad eos propius accedentes, in quantum poterant, prohibere conabantur, ne de ore ipsorum divinae laudis sonus inter Gentiles audiretur populos.
But another story concerning the great and wonderful power of his voice should not be omitted. The fact is said to have taken place near the fortress of King Brude. When the saint himself was chanting the evening hymns with a few of the brethren, as usual, outside the king’s fortifications, some Druids, coming near to them, did all they could to prevent God’s praises being sung in the midst of a pagan nation. On seeing this, the saint began to sing the 44th Psalm, and at the same moment so wonderfully loud, like pealing thunder, did his voice become, that king and people were struck with terror and amazement.
