Saint Petroc of Cornwall

Abbot, Confessor, and Chief of the Cornish Saints c. 468 – c. 564 (some traditions, c. 594) Feast: 4 June


Identity and Origins

Saint Petroc — known also as Petrock, Pedrog, or in the Latin of his vitae Petrocus — stands among the foremost of those holy men who gave to Cornwall the ancient title of the land of saints. Tradition places his birth in the latter half of the fifth century in south Wales, in the kingdom of Glywysing (the modern Glamorgan), and names him a son of the king Glywys, so that he belonged to that Christianized Celtic nobility from which so many enlighteners of the British peninsula sprang.

It is fitting that the historian should here note a caution which honesty requires. The surviving Vitae S. Petroci — the so-called “first life” and “second life” — are medieval compositions, the earliest written form dating only from the twelfth century, and the manuscripts that endure come chiefly from Brittany, the English copies having perished in the dissolution of the monasteries under Henry VIII. These accounts therefore testify directly to the medieval cult of the saint rather than to the conditions of the sixth century, and they weave together genuine historical memory with the legendary embellishment characteristic of the age. We may nonetheless trace the principal contours of his life with reasonable confidence, for the vitae rest upon older oral tradition, and the wide dedication of churches across Cornwall, Devon, and into Somerset — the territory of the sub-Roman kingdom of Dumnonia — bears independent witness to a real and influential apostle.

Declining the earthly crown that was his by birth, Petroc embraced the monastic life. With a company of companions he crossed to Ireland, then the great school of Western sanctity and learning, where he gave himself to study of the Sacred Scriptures and the ascetic discipline of the Celtic monasteries — a discipline drawn, in no small part, from the desert fathers of the Egyptian Thebaid and of Syria.

Manner of Life and Virtues

An early manuscript preserves a description of the saint that is worth setting before the reader entire: he was “handsome, courteous in speech, prudent, modest, burning with unceasing love, always ready for all good works for the Church.” In these few words the vita sketches the very pattern of the Christian abbot — comeliness of body subordinated to comeliness of soul, learning joined to humility, and charity made the fire of every labour.

His sanctity was marked above all by gentleness and by that affection for the creatures of God which has caused later writers to compare him to Saint Francis of Assisi. Two stories endured most tenaciously in the popular memory. In the one, a hunted stag fled to Petroc for refuge, and the saint sheltered it; the king who pursued the beast, struck by the holiness of the man, granted him the very land on which he would raise his monastery. In the other, Petroc took into his protection a wolf which had been driven and hunted, and the beast became his faithful companion. Such tales belong to a wider current of Celtic hagiography — one thinks of the fox of Saint Ciaran or the blackbird of Saint Kevin — wherein the gentleness of the saint toward the wild creature signifies the restoration of that peace between man and creation which sin had broken, and which holiness, in some measure, begins to repair.

After many years labouring at Lanwethinoc — the place that would take from a later disciple the name Padstow, Petroc’s stow, or Petroc’s holy place — the saint felt the call to deeper pilgrimage. He journeyed, the tradition holds, to Rome and to Jerusalem; and certain later accounts carry him even to the shores of the Indian Ocean, where he is said to have lived as a hermit upon an island. This last is the most plainly legendary of the elements of his life, resting on no firm evidence and reflecting rather the medieval imagination’s love of the marvellous and the far-flung; the editor must flag it as such, though long-distance travel along the old Roman trade routes was not in itself impossible.

Ecclesial Role and Apostolate

Returning to Cornwall, Petroc gave the remainder of his long life to the founding of religious houses and to the conversion and confirmation of the Dumnonian people in the Faith. He built a chapel at Little Petherick (Nansfenten) near Padstow and gathered there a community of his followers. He is credited above all with the foundation of Bodmin, which became for centuries the religious capital of Cornwall, for a time an abbey-bishopric, and the chief centre of his cult. In his last years, ever drawn to solitude, he withdrew to Bodmin Moor to live as a hermit in simplicity and prayer, and there too disciples gathered to him, and there the renown of his miracles spread.

So thoroughly did his apostolate stamp the region that he is reckoned, together with the Archangel Saint Michael and Saint Piran, among the three patrons of Cornwall, and is honoured by the title Chief of the Cornish Saints. The dedications that bear his name in Cornwall, Devon, Wales, and Brittany — Padstow, Bodmin, Little Petherick, Saint-Méen in France, and many more — map the breadth of a veneration that outlasted the centuries.

Death and Veneration

Saint Petroc died, full of years and merit, while visiting his disciples — the vitae place his death between Nanceventon and Lanwethinoc, near a spot called Trereval — and his soul passed to the reward of the faithful servant. The traditional datings vary: older accounts favour about the year 564, while others, following the medieval lives, give a date near 594. The discrepancy is here noted for the reader’s judgment; it cannot be resolved with certainty from the surviving sources.

His relics were enshrined at Bodmin and venerated there throughout the Middle Ages, until they were dispersed at the time of the English Reformation. Yet a precious witness survives: the medieval ivory casket, of Sicilian-Islamic workmanship, which once held his bones, is still preserved and displayed at the parish church that bears his name in Bodmin — a mute and beautiful testimony to the honour in which Cornwall held its chief apostle.

Spiritual Lessons

The life of Saint Petroc, even read through the haze of legendary accretion, sets before the soul several enduring lessons.

First, the renunciation of a royal inheritance for the poverty of Christ teaches that the goods of this world, however lawful, are rightly counted as loss for the surpassing knowledge of Christ Jesus. Petroc’s crown was exchanged for a cell, and in the exchange he gained a kingdom that does not pass.

Second, his gentleness toward the hunted stag and the driven wolf is no mere sentiment toward beasts, but a sign of the interior peace of one wholly given to God. The saint who has made peace with his Creator becomes, in some degree, a centre of peace for the whole of creation around him, foreshadowing that final harmony when the creature itself shall be delivered from the servitude of corruption.

Third, the rhythm of his life — labour in community, pilgrimage, and finally the hermitage — shows the proper relation of action and contemplation. He did not flee the world before he had served it, nor did he cling to his works when God called him at the last to the solitude of pure prayer.

A Prayer to Saint Petroc

The following collect is composed in the traditional idiom for private devotion; it is not a received liturgical text of the Roman Missal.

Deus, qui beátum Petrocum abbátem, regni terréni contemptórem, in solitúdine et caritáte clarum effecísti: concéde propítius; ut, eius exémplo et intercessióne, mundi illécebras despiciéntes, tibi soli adhærére mereámur. Per Christum Dóminum nostrum. Amen.

O God, who didst make blessed Petroc the abbot, a despiser of an earthly kingdom, renowned in solitude and in charity: mercifully grant that, by his example and intercession, we who despise the allurements of the world may be found worthy to cleave to Thee alone. Through Christ our Lord. Amen.

For Further Study

Those who wish to go deeper may pursue this saint along several of our learning paths:

  • Lives of the Saints — to explore the wider company of the Celtic and Cornish saints (Piran, Ciaran, Kevin, Brendan) among whom Petroc shines, and the ascetic tradition they drew from the desert fathers.
  • Church History — to study the conversion of sub-Roman Britain and the monastic mission of the Apostolic and post-Apostolic ages in the Celtic lands.
  • Sacred Liturgy — to understand the place of the confessor and abbot in the traditional calendar and the Commune Abbatum of the Missale Romanum.

A note on sources: the principal narrative derives from the two medieval Vitae S. Petroci and the Miracula*, supplemented by Cornish local tradition and the Roman Martyrology. As these blend history with legend, the dating, the Indian pilgrimage, and the animal miracles are presented with the caution noted above, and any element intended for catechetical use should be verified against the Bollandist* Acta Sanctorum (under 4 June) before publication.


If you wish to go deeper, the Lives of the Saints path will lead you through the holy enlighteners of the Celtic lands and the ascetic ideals they embodied.
