Question: Cantabrian mythology was likely diluted by what Iron Age mythology?
Context: The ojáncanu or ojáncano (: (Western) [oˈhaŋ.kanu] or (Eastern) [ɵˈxɐŋ.kɐnʉ]) is a cyclops of Cantabrian mythology.  This creature embodies evil, cruelty, and brutality.  This giant cyclops is the Cantabrian version of the Greek Polyphemus that appears in other Indo-European mythologies. The Anjana (: (Western) [anˈhana], (Eastern)[an.xa.nɜ]; ] ) (from "jana", a former word for witches during the Middle Ages) are one of the best known fairies of Cantabrian mythology.  These female fairy creatures foil the cruel and ruthless Ojáncanu.  In most stories, they are the good fairies of Cantabria, generous and protective of all people.  Their depiction in the Cantabrian mythology is reminiscent of the lamias in ancient Greek mythology, as well as the xanas in Asturias, the janas in León, and the lamias in Basque Country, the latter without the zoomorphic appearance. Cuélebre (Asturian) or Culebre (Cantabrian), is a giant winged serpent-dragon of the Asturian and Cantabrian mythology, that lives in a cave, guards treasures and keeps "xanas" / "anjanas" as prisoners.  Although they are immortal, they grow old as the time goes by and their scales become thick and impenetrable, and bat wings grow in their bodies.  They don't usually move, and when they do it, it is in order to eat cattle and people.  One can kill the cuélebre giving him as meal a red-hot stone or a bread full of pins.  Its spit it is said to turn into a magic stone which heals many diseases. Spanish mythology refers to the sacred myths of the cultures of Spain.  They include Galician mythology, Asturian mythology, Cantabrian mythology, Catalan mythology and Basque mythology.  They also include the myths and religions of the Celts, Celtiberians, Iberians, Milesians, Carthaginians, Suebi, Visigoths, Spaniards, Moors of Spain, and some Roman and Greek mythology. The xana is a character found in Asturian mythology.  Always female, she is a creature of extraordinary beauty believed to live in fountains, rivers, waterfalls or forested regions with pure water.  She is usually described as small or slender with long blonde or light brown hair (most often curly), which she tends to with gold or silver combs woven from sun or moonbeams.  The origin of the Asturian word "xana" is unclear, though some scholars see it as a derivation from the Latin name for the goddess Diana.  References to where the mythological xanas lived are still common in Asturian toponyms.  They also appear in Eastern Galician and Cantabrian mythology (Anjanas). The Caballucos del Diablu (Cantabrian for "(little) horses of the devil") is a myth from the Cantabrian mythology, a region of northern Spain. Celtic mythology is the mythology of Celtic polytheism, the religion of the Iron Age Celts.  Like other Iron Age Europeans, the early Celts maintained a polytheistic mythology and religious structure.  Among Celts in close contact with Ancient Rome, such as the Gauls and Celtiberians, their mythology did not survive the Roman Empire, their subsequent conversion to Christianity, and the loss of their Celtic languages.  It is mostly through contemporary Roman and Christian sources that their mythology has been preserved.  The Celtic peoples who maintained either their political or linguistic identities (such as the Gaels in Ireland and Scotland, the Welsh in Wales, and the Celtic Britons of southern Great Britain and Brittany) left vestigial remnants of their ancestral mythologies, put into written form during the Middle Ages. In Cantabrian mythology, a ramidreju (: [ramiˈdrehu]) is a creature said to inhabit the mountains and forests of Cantabria, in northern Spain.  This animal, which resembles a weasel, is born once every hundred years from a weasel or a marten.  These mythological creatures has a very long body, like a snake, and their fur is slightly green-colored.  Its eyes are yellow and its nose is like that of a hog, which it uses to dig very deep holes.  Ramidrejus are a very sought-after animal in Cantabrian folklore because their fur heals every sickness and the animal has a strong desire for gold. Muna (Mona, Muma) is one of the goddesses of Celtic polytheism, associated heavily with the written word.  She is also the largest influence and likely synonymous with multiple fae whose folk roots are a religion of the Iron Age Celts.  These fae's most notable influence was as a protector of lost children.  Like other Iron Age Europeans, the early Celts maintained a polytheistic mythology and religious structure.  Among Celts in close contact with Ancient Rome, such as the Gauls and Celtiberians, their mythology did not survive the Roman empire, their subsequent conversion to Christianity, and the loss of their Celtic languages.  It is mostly through contemporary Roman and Christian sources that their mythology has been preserved.  The Celts peoples who maintained either their political or linguistic identities (such as the Gaels and Brythonic tribes of Great Britain and Ireland) left vestigial remnants of their forebears' mythologies, put into written form during the Middle Ages.  Muna was the inspiration for the naming of the province Munster in Ireland. Cantabrian mythology refers to the myths, teachings, and legends of the Cantabri, a pre-Roman Celtic people of the north coastal region of Iberia (Spain).  Over time, Cantabrian mythology was likely diluted by Celtic mythology and Roman mythology with some original meanings lost.  Later, the ascendancy of Christendom absorbed or ended the pagan rites of Cantabrian, Celtic and Roman mythology leading to a syncretism.  Some relics of Cantabrian mythology remain.
