This covers some of the Gods and Goddesses from the Mythological Cycle. I have tried to cover their many incarnations in the Celtic, Scottish, Welsh and Irish mythologies.

Dana or Danann or Danu or Danand are all the names for the most commonly recognized Goddess of the Celtic Pantheon. She is known from the Mythological Cycle of the Irish Traditional Histories, from the Fourth Invasion of the Tuatha De Danann.

It is suggested that Danann comes from the ancient times of the Celts, described as the River Goddess, Dany, root of which is the formation of the Danube, the European river, and is also the name of the river goddess in Sanskrit literature.

The Irish had a formula for describing great people of importance. The greater or more important a person, hero or God or Goddess was, the taller his or her stature. Much as the descriptions in the Bible depict persons of wisdom and importance by the great number of years he or she lived, so to, great Gods, Goddesses and Heroes of Ireland were depicted as giants. Little is said about Danann in the written histories. She was married to the Giant Tuireall, and she had three sons, Brian, Iuchar and Iucharba, who killed the father of Lugh, who had killed their father. She also had a daughter Ethne. In some later versions, Tuireall is the alternative name for Dealbhaoth, who is Danann's father. But there are various paternity's given and Dealbhaoth has daughters of similar name, and, being written so late, could be easily confused.

The Danann also appears in medieval Welsh literature as Don (also the Scottish, as in River Don) the mother of a family of mythical wizards, and her sons are Ameathon, Gilvaethwy/Gilfaethwy, Gorannon/Gofannon, Gwydyon and daughters Arianrhod and Penardun/Penarddun.

Gilvaethwy and Gwydyon make their appearances in the fourth story of the Mabinogion, as Gilvaethwy rapes the virgin Goewin, Math's Virgin, and Math turns them both into animals, alternating sexes, and producing three sons, Bleiddwn, Hyddwn and Hychdwn the Tall. In another story, not in the Mabinogion, Gwydyon kills Pryderi. Arianrhod is the Mother of Lieu and Dylan by her brother Gwydyon.

Anu (also Ana) is the name medieval writers identified with Danann, and is connected with the Old Irish "anai" which means wealth and is described as the Goddess of Prosperity of Munster. Ireland is also described in an early text as "lath nAnann" (the land of Anu) and there are two mountain tops near Killarney called "Da Chich nAnann" (Two Paps (breasts) of Anu). She is also the fertility goddess, the earth goddess, and is sometimes associated with the Morrigu, one of the triple aspects, with Badb and Macha, and is the Maiden aspect of the Triple Goddess.

In all traditions, Dana is the Mother of the people, and is treated with respect. She is the Great Mother, the Moon Goddess,, Patroness of Wizards and rivers.

Dagda or Daire, the Good God, was the High King of the Tuatha De Danann. He was also known as Eochaid Ollathair (Father of All) and Ruadh Rofessa (The Red One of Perfect Knowledge). He was called "Dis Pater" by Caesar who wrote that the Gauls regarded him as an ancestral Deity.

He was a giant, generous and had a "Voracious" appetite. He possesses one of the Four Noble Treasures, the Cauldron of Dagda, the Undry, from which "no company ever went away unsatisfied".

The pages of pseudo-history and medieval literature are filled with references to his deeds, his hugeness and his adventures on the battlefield with his huge club. It has been speculated that he did everything from single handily building New Grange (in Co. Meath) to being the Cerne Abbas Giant (the great chalk giant, also thought to be Herakles).

Though he had the Mor-Rioghain (Morrigu) as his wife, as well as a Fomhoire woman as a consort, more is known of his children, which include Breo-saighead (Brigit), MacOg (Angus), Aodh, Caomh, Ceals, Cearmaid, Ogma, Midir, Brodh the Red, Ainge and, in one story, Dian Ceacht, the physician.

He is said to have died from a wound received from Certhleann, wife of Balar, who stabbed him with a javelin, and though he survived, it took its toll in his later years, after he had become King when Lugh dies, and had ruled for 80 years.

In Britain, he is associated with Sucellus, the God of the Sky, the father, the God of the Mallet. His consort is Nantosuelta, the river goddess, associated with the Morrigu.

He is the All Father, the Great God, Lord of the Heaves, Father of the Gods and Men, Lord of Life and Death, the Arch-Druid. He is the god of perfect knowledge, of death and rebirth, master of magic, and the father of his people.

Nuuada Airgetlam, Nuadhu, is the King of the Tuatha De Danann. It was he who led the TDD to Ireland. In the first battle between the Firbolg and the TDD, Steang the Firbolg slashed off Nuada's arm at the shoulder. A king missing parts was king no more in the TDD Tradition, so Nuada resigned as king. Bress the Beautiful, a Fomorian who was married to the TDD Brigit (to make peace with the Fomorians) became king for seven years. Lugh poisoned him, and Nuada, who now possessed a silver arm made for him by Dian Ceacht, the magical physician, was make king again. Nuada possessed the :Sworn of Nuada" one of the Four Noble Treasures. From this sword no opponent could escape and no wound inflected by it could be healed.

He is closely associated with the British Celtic Nodons/Nodens, who had a temple in Glouchestershire. There are representations of dogs at the temple, suggesting he was a Hunter God, but there is also a man hooking a fish, tying him to water and rivers, as he was married to Boinn, the river goddess. He is also associated with the mystical Salmon in medieval literature.

In the Welsh, he is Lud/Llud/Llud llau Eunt/Llud of the Silver Hand. His mother is Arianhod, Daughter of Don, and his father is Gwydion, her brother. His birth and his story is in the Mabinogion, in the story of Math.

In the Irish, Nuadha has no children mentioned, but he has consorts in the Goddesses Fea, Neimon, Badb, and Macha, all being the Morrigu.

In all traditions he is regarded as the Chieftain god. He is bestowed with the titles "He who bestows wealth" the Cloud-Maker" and is considered the god of healing, water, ocean, fishing, the Sun, sailing, childbirth, dogs, youth, beauty, spears and slings, smiths, carpenters, harpers, poets, historians, sorcerers, writing, magic, warfare and incantations.

The Mor-Rioghain, the Morrigu, Morrigan, Maeve, Medb, Meadhbh, Maimh, Neamhain, Neman, Fea, Be Neit. These all describe the "Great Queen" or are the personas included in the triad commonly called, "The Morrigu". These names function as alternative appellations or identifications for her. She is the three phases of the Silver Moon, the waxing, full and waning. Her symbol is the crow or the raven. She is the Crone aspect of the Goddess. She is the three fold goddess. In each of her aspects she is represented as three, most commonly Morrigu, Macha and Neman, older is Badhbh, Neamhain and Macha. And in all her apparitions, she is the Goddess of war, fate and death. She is the wife of the Dagda and consort of Nuada.

Due to the regional variations, language and local customs, she has many names. Neamhain was the wife of Net, the God of battle of pagan Ireland. The names similarity to Neimheadh, who lead the second invasion of Ireland, suggests an absorption of traditions. Similar is Mor Mumhan or Mor of Munster, root of Mor Rioghain, coming from Mugha or Mugham, the name of a goddess of the Erainn people of Munster.

The names are also suggestive of emotional feelings that her many names suggest. Nemon is venomous, Badb is fury, Macha is battle and Fea is hate.

The Macha name signifies a pasture and was possibly originally a land goddess. In one medieval account, she was the daughter of one of the three kings, who ruled alternately for seven years each time. When her father died, she demanded a share for herself. They refused, she fought them, and won. Another story has her a consort to the Ulster Farmer Crunnchu and, pregnant by him, was forced to run against King Conchobhar's horses, due to her husbands bragging. She raced, won, dropped and gave birth to twins and cursed the Ulstermen, which came to pass. In this story there is a suggestion that she is related to the Celtic horse goddess known in Europe as Epona and the Welsh Rhiannon.

In Britain, she is closely united to Nantosuelta, Winding River Goddess, consort of Sucellus, who is associated with Dagda. Her familiar is also the raven. Also associated with her is the British Nimue, the Celtic Moon Goddess, also called Viviene.

In Scotland, she is associated with Callich Beine Bric, the Veiled One, Destroyer Goddess of the Underworld, also called Scota (root of Scotland). Scotland was also called Caledonia, or Land given by the Caillech. She is pictured with a blue face, or three blue faces.

Badb/Badb Catha/Badhbh is the word for scaldcrow, a favorite form of the goddess. Badhbh is the mother aspect of the goddess, War goddess, wife of Net, Sister to Macha.

Meadhbh is from the Ulster cycle, the Connacht queen, wife of Ailill mac Mata and mother to the seven fictional sons called Maine or the Maini.

In the Welsh, she transforms into Morgan Le Fey, her symbol being the Pentacle.

She is generally regarded as the goddess of war, and also Queen of Phantoms, Queen of the Fey, shape shifter patroness of priestesses and witches.

Brighid (also Brigit earlier) Bride, Brid. Her name means "The exalted one". Daughter of Daghdha, one of the Tuatha De Danann (TDD),. She was called a poetess. Earlier works claim her as Breo-Saigh'it "Fiery arrow". The Flame of Ireland. She was so popular with the common people that the Church would not write her out of history. Circa 600 CE are the earliest known writings of "Brighid" of Leinster. She becomes the founder of a convent in Kildare. She is considered to be a truly "Pious woman" and was designated as "Another Mary".

In the Mythology cycle, she was married to Breas, the son of the Formian King. Breas was King in Tara for 7 years, till he was killed in a hunting accident. Nuada then ruled again, as he had been made whole with the magical Silver Arm.

Caesar included Brighid in his histories and labels her as "Minerva".

Her major attributes are poetry, traditional learning, divination and prophecy, as well as being an early fertility goddess. She had two sisters, by one account, both called Brighid (triple goddess?). One sister is associated with healing and one with the Smiths Craft (Cormacs glossary cir 900 CE).

Even in her Church appearance, the mythological cycle touches much of the same elements. Her feast day is February 1st, same as Imbolc, festival of spring, and the birthing of the lambs.

A notation, in Vedic Sanskrit "brihati" was used as a divine epithet, "exalted one". It also has close association with the British "Briganti" (high one) and the Latin "Brigonti" (the exalted one). Her name is associated with the rivers Brighid in Ireland, Braint in Wales and Brent in England.

Diancecht/Dian Cecht whose name means Swift Power or he who swiftly travels. Grandfather of Lugh, and Physician/magician of the TDD.

In the first Battle of Moytirra, he and his two sons and a daughter make a well into which the wounded TDD are cast to be healed, while the family sings incantations. It was he who made the silver arm for Nuada and healed him. His knowledge of Herb's was unexcelled. He made draughts to cure, healed wounds and replaced damaged body parts.

His sons were Miach, Cian, Cethe, Cu and a daughter Airmid. He is revered as the God of Medicine, healing and silver works.

Goibhniu was the Smith of the TDD. His name is a derivative of "Gobha". (modern is Gabha). Both mean smith. The spears he fashioned always hit their mark and their wounds were fatal.

He also is reputed to have held an Ale Feast for all the TDD and all who ate and drank at the feast were given invulnerability. This follows the Greek Myths, where Hephaistos the Smith also gave drink to the Gods.

In Wales he is called Gofannon. Under both names he is the God of Smiths, metal workers, fire and brewing.
