God’s teeth? No, that oath came about a thousand years later. By the angel!? Nope, wrong book series. (10 points if you comment and can tell me which one it’s from.) Merlin’s beard! Okay, maybe that one.
It’s tough to say by whom Guinevere and Arthur would have sworn or exactly what sort of faith they may have professed, other than it was likely influenced by both Druidism and Christianity. Of course, I make assumptions in my books to suit my fiction, but in their historical time (approximately 475-530 AD), Celtic religion encompassed a variety of influences, especially those from the Roman Empire, and beliefs varied from tribe to tribe. But here are a few generalizations we can make:
They loved nature – Did you know there were no Celtic churches? That’s because the Celts believed in worshiping in nature, rather than in man-made temples. Oak groves, stone circles and sacred springs were about as close as they got to holy structures, and those shrines usually were tended to or presided over by a Druid. (No, Merlin did not build Stonehenge; neither did the Druids. It was actually built several thousand years before the Arthurian period.) Because of their close association with nature, the Druids were believed to be able to control the weather. There was also some belief the Druids could shape shift into animal form, which was probably derived from the shamanistic practice of wearing the animal skin/horns/feathers in ritual to invoke its power, similar to Native American practice. And no, they didn’t sacrifice people on a mass scale. Possibly a few here and there, but why, when and how is up for debate.
They had a god/goddess for everything – The Celtic connection to nature and their agrarian lifestyle also influenced the way they saw their deities. They loved triple symbolism, so often their deities show up in three-fold form. For example, the Goddess is said go through a whole life cycle each year: maiden (spring), mother (summer and fall) and wise woman (winter). Likewise, the God was said to live through three phases each year: young child (late winter/spring), strong man/lover (summer/early fall), and dying old man (late fall/early winter), who would be reborn on the midwinter solstice along with the sun. (More to come on the Celtic calendar and how their holy days fit in a future post.)
So, with all these options, who you gonna call? (No, not Ghostbusters.) The answer depends on what you need. If you were a Celtic blacksmith, a woman in labor or just in need of some poetic inspiration, you’d invoke the goddess Brigid. Going into battle? Mirthas might be your man. (He’s a Roman god adopted by the Celts during the Roman occupation. There’s even some speculation that he was Arthur’s preferred god.) If a goddess is more your style, call on the Morrigan to aid your fight.
Some deities were specific to a location such as a sacred spring or holy grove (the goddess Coventina was worshiped at a spring near Hadrian’s Wall), while others were tribal deities who date back into the murky past of the pre-Roman Celts. And some were more popular and wide-spread than others, such as the goddesses Airanrhod, Branwen, Blodeuwedd, Rhiannon and Cerridwen, especially beloved in what is now Wales, or the gods Cernunnos (the Horned One), Herne (the Hunter) or Lugh (Lord of Light).
They co-existed with Christians – There’s great debate in the historical community about when Christianity came to Britain (probably sometime around 300-400 AD, but it wouldn’t rise to total prominence for a few hundred more years) and even greater debate among Arthurian scholars as to whether or not Arthur was Christian. (Most stories have him being Christian, but they were written well after Christianity became the dominant religion.) In reality, Guinevere and Arthur’s beliefs could have gone either way because that time period was one of transition where the old ways (Druidism) were dying out, but not completely dead, and the new power (Christianity) was rising, but didn’t quite have a hold. I’d love to tell you how that plays out in my books, but you’ll have to wait to read them to find out.




Arthur Pendragon – Son of Lady Iggraine (Grainne/Ygerna) and High King Uther Pendragon. As the story goes, Uther fell in love with Iggraine while she was married to a lord named Goloris. While Goloris was out at a battle, Uther snuck in to see Iggraine (in some cases Merlin cast a spell on him to make him look like Goloris) and bow-chica-wow-wow, Arthur was conceived. When Merlin found out about the child, he arranged from him to be raised by Lord Ector for his own safety, and so Arthur grew up ignorant of his paternity. Depending on who tells the tale, sometimes it is Merlin who tells him, sometimes Uther, other times he finds out through magical means (i.e. sword in the stone). In some versions of the story, Arthur is Morgan’s brother. He is always Mordred’s father. Arthur traditionally is mortally wounded at Mordred’s hand during the battle of Camlann. Some say he died on the battlefield, others in Avalon, while some say he did not die (just like Elvis) but sleeps, waiting for the call to save the world once again.
Guinevere – Daughter of Lord Leodgrance or Leogden. Nothing is ever said about her mother, siblings or early life. She marries Arthur and becomes High Queen. In most traditions she is Christian, but is sometimes associated with the isle of Avalon. Most of the time she’s barren, but a few authors give her a child, usually a son, who dies in childhood. She is often kidnapped, most famously by a rebellious Lord named Malegant or Melwas, and sometimes even by Mordred. She is famous for her affair with Lancelot, which may or may not have been sexual. When Mordred discovers their affair, Guinevere is sentenced to death for treason, but is rescued by Lancelot. She is said to either have died of grief after Arthur’s death or lived out her days in penance in a convent.
Lancelot (du Lac) – Arguably the most famous Knight of the Round Table. He is usually from Brittany and sometimes the son of their Lady of the Lake (it’s a title, so there can be more than one), but most often he doesn’t know who is parents are. Lancelot is always known for his skill with a sword, and sometimes also with the ladies. Though the popular musical paints him as arrogant, that is not a common trait. He fights for Guinevere out of love that may be chaste or something more, depending on tradition. He is instrumental in the quest for the Holy Grail and is sometimes one of three knights who are allowed to be in its holy presence (the other two are traditionally Galahad and Perceval). Once his affair is discovered, Arthur banishes him to Brittany, but he comes back in time to save Guinevere from death. He traditionally enters a monastery in repentance for his sins and there eventually passes away.
Merlin – Merlin may be a title given to the Archdruid or it may be a name, no one knows for sure. Merlin is usually the son of a nun and a demon (because that makes sense). He always has prophetic powers and is Arthur’s chief advisor. In some traditions, Merlin doesn’t age, so he provides advice to Vortigern (a king several generations prior to Arthur), aids Uther in Arthur’s conception and guides Arthur throughout his reign – all in a single lifetime (see why I favor the title theory?). In a few stories, he even ages backwards. Merlin is said to have foreseen the affair of Guinevere and Lancelot and the resulting fall of Camelot and so was against Arthur’s marriage to Guinevere, as well as his acceptance of Lancelot at court. Merlin’s fate is questionable. Some say he fell in love with Nimue, a witch or priestess who cast a spell on him to steal his power and then entombed him in a glass or air tower or ancient oak. Others say he went mad during a battle (possibly Camlann) and ran raving into the forest, never to be seen again.
Morgan (le fey) – Morgan started out in Arthurian legend as a healer or priestess. She is often cited as one of the nine holy women of Avalon. Somewhere along the way she became Arthur’s sister and all hell broke loose. In some traditions she competes with Arthur for the throne, while in others, she simply wants to kill him. She and Guinevere have a natural dislike of one another and Morgan sometimes tries to kill or sabotage the Queen. No matter her relation to them, Morgan is almost always Mordred’s mother (her sister Morgause/Ana is his mother in early legend) and fights for her son’s claim to the throne. In some versions, she accompanies a mortally wounded Arthur back to Avalon after the battle of Camlann. Beyond that, her final fate is unknown.
Okay trivia and history buffs, listen up. Here are 10 things you probably didn’t know about the Celts and probably should before reading my books:

I’m starting to realize that research isn’t just something you do before you write a novel, while you are conceptualizing the plot. Yes, that is a VERY important step, but you can’t rest on your laurels after that, especially if what you write edges anywhere near historical fiction or has any subject in it about which are not already an expert. Readers know things you’d never expect them to and they know when you’re making stuff up. To quote the movie Pump Up the Volume, they can “smell a lie like a fart in a car.” (Crass, I know, but I bet it made you laugh!) And the last thing you want to do is be disingenuous to your readers.
