Sanctan

Saint Sanctan, whose name also appears as Sanctain, Santan, and Sanctanus, was a Christian bishop of the sixth century, commemorated in the early Irish martyrologies as bishop of Cill-da-les (Cell da les). The location of that church is not certainly known. Later Irish topographical tradition has commonly identified it with Kilnasantan (Cill na Sanctan, meaning the church of Sanctan) in the old parish of Tallaght, County Dublin, in the neighbourhood of present-day Templeogue. The Martyrology of Donegal, compiling earlier sources, describes him as bishop of Cill-da-les and adds that he was of the Britons. His feast is entered on 9 May in the Martyrology of Tallaght, the Martyrology of Gorman, and the Martyrology of Donegal. No contemporary biography survives, and neither the year of his birth nor the year of his death is recorded.

The principal narrative tradition about his life is contained in a Latin hymn preserved in the Irish Liber Hymnorum and in the Old Irish preface attached to that hymn. According to this account, Sanctan crossed the sea from Britain together with Matoc (also called Madoc), who is described in the sources variously as his brother or as his sister's son. The two are said to have reached Ireland and to have left Britain behind them. Irish and Welsh genealogical collections of a later date, which must be used with caution, present Sanctan as a son of Sawyl Penuchel (Samuel the Proud), a British ruler whom Welsh tradition associates with the northern Brittonic world and with the line of Pabo Post Prydain, and of Deichter, a daughter of Muiredach Muinderg, a king of Ulster. If these affiliations preserve any historical memory, they would situate Sanctan among the British and Ulster elites of the later fifth or sixth century and would help to explain a career that moved between Britain and Ireland.

After their arrival the two kinsmen are represented as following the eremitical life. Matoc is said to have remained a hermit on an island named Inis Matoc, while Sanctan was raised to the episcopal office. The hymn itself is said to have been composed by Sanctan on a journey to visit Matoc. The preface offers two explanations of its language and inspiration: either Sanctan did not yet know Irish well and received angelic assistance, or he composed the piece after he had acquired the language. These details, typical of medieval Irish learned tradition, cannot be verified independently, but they portray Sanctan as a British-born cleric who adopted the language and ecclesiastical life of Ireland and who combined the roles of hermit and bishop, a pattern well attested among sixth-century saints of the Irish and British churches.

In later centuries his cult was attached to more than one church. Kilnasantan in County Dublin preserved his name in its toponym. On the Isle of Man the parish church of Kirk Santan, in the parish of Santon, is dedicated to him, and he is regarded as the patron of that parish; whether the Manx dedication records a personal mission by the same bishop, a transfer of cult from Ireland, or a local homonym cannot be established from the existing evidence. He belongs to the large company of British and Irish monastic bishops whose holiness was recognized by local liturgical commemoration rather than by any later papal process of canonization. Beyond the martyrological notices, the hymn and its preface, the genealogies, and the church dedications, nothing certain is known of his acts, the place of his death, or his burial.
