Helen of Caernarfon

Saint Helen of Caernarfon or Helen of Carnarvon, known in Welsh tradition as Elen Luyddog (Helen of the Hosts), was a late 4th-century founder of churches in Wales who is remembered as a saint. Traditionally she is said to have been a daughter of the Romano-British ruler Octavius (Eudaf Hen) and the wife of Emperor Magnus Clemens Maximus or Macsen, Emperor in Britain, Gaul and Spain, who was killed in battle in 388. She is commemorated on May 22.[1]

Church tradition

Elen was mother of five, including a boy named Cystennin (or Custennin or Constantine). She lived about sixty years later than Helena of Constantinople, the mother of Constantine the Great with whom she has, in times past, been confused. She is patron of Llanelan in West Gower and of the church at Penisa'r-waun near Caernarfon, where her feast day is May 22.[1] Together with her sons, Cystennin and Peblig (Publicus, named in the calendar of the Anglican Church in Wales), she is said to have introduced into Wales the Celtic form of monasticism from Gaul. Saint Gregory of Tours and Sulpicius Severus record that Maximus and his wife met Saint Martin of Tours while they were in Gaul.

Literary tradition

Elen's story is told in The Dream of Macsen Wledig, one of the tales associated with the Mabinogion. Welsh mythology remembers her as the daughter of a chieftain of north Wales named Eudaf or Eudwy, who probably lived somewhere near the Roman base of Segontium, now Caernarfon.

She is remembered for having Macsen build roads across her country so that the soldiers could more easily defend it from attackers, thus earning her the name Elen Luyddog (Elen of the Hosts).

Since many characters in these tales are thought to be Christianized reflections of older deities, it has been suggested that Elen reflects (along with Rhiannon, etc.) a tradition of goddesses of sovereignty.[2]

She is said to have ordered the making of Sarn Helen, the great Roman road running from Caernarfon to south Wales via Dolgellau, Pennal and Bremia (Llanddewi Brefi). Though this road bears her name it is considerably older than Elen's accepted time period. Many other Roman roads in Wales bear her name (e.g. Llwybr Elen) and she is thus acknowledged as the patron saint of British roadbuilders and the protectress of travellers. The Welsh translation of Legion is Leng, therefore the Roman road called Sarn Elen could also be a mutation of Sarn y leng (The Legions Road).
