I am sorry; I do not know.

No idea.

As far as I know, nobody knows the real history about King Arthur. 

Let me say, however, that I was a bit perplexed when reading your statement:

"I have some thoughts that Arthur was somewhat myth more than reality and if there was a man, he may have been gay as his wife and right hand man were off together"

Why do you have such thoughts? What would be the problem if he were gay?  More to point, I cannot see in your questions any scientific interest! There are some questions that are (e.g., was King Arthur gay?), so to say, no scientific questions at all. Like Joaquín and Alipate I have no idea about your questions. May be you could look at Wikipedia before raising your questions.

In your topics you have the term morality. As I see it, to ask for the sexual orientation of King Arthur is, as it were, an immoral question because the main injunction of justice or morality is that any individual should be treated with respect regardless of his/her age, gender, nationality, ethnicity, political, religious or sexual orientation, and so forth.  

I truly apologize for being  a bit negative in my answer. To respect you, I prefer to be frank and sincere instead of being politically correct.

Best regards

Thanks for your response. I think you may have taken my question in the wrong light.

I  was thinking of a topic for a paper that was more of a unique perspective. After working with some of the arthurian stories and watching some documentaries and movies, I could not help thinking that there may be a possibility that Arthur may have been gay and the stories of all his knights and escapades may have been diversions as well as good for the nation. No judgement behind the statement of his sexual orientation, just more of a theory that I wondered if anyone may have had any leads, suggestion, or study in an academic orientation that may have suggested or helped in that way. Through google, there is not much. As to his existence, again, yes myth with much research as to the possibility of an existence of a man by that name. And, as to the rest, morality is not  my question just a direction that may lead to deeper research.

Ghassan, I fear you are starting from an over-simplified, and essentially false premise.

You speak of watching documentaries, movies, and unspecified, I presume written, stories.  Which may be modern novels.

The fact is, the Arthurian tradition has been continually rewritten for generation after generation for over around 1200 years.  And most of the modern films and documentaries take a very simplified approach to what is a quite complex mass of medieval stories.

If there was an Arthur, he was probably a British battle leader who delayed the Saxon penetration of Britain by about 40 years.  The earliest reference to Arthur is in a 9th century list of battles he is supposed to have won.  See the link Historicity of King Arthur.

Arthur also appears in a number of early Welsh poems that may go back to the 11th century, and, from memory, 3 saints lives.  Two Welsh triads claim that Arthur had three wives, all named Guinevere, and three mistresses.  So no suggestion he was gay there.  His regular companions are Kay (Cai) and Bedivere (Bedwyr). See the Brittania link.

In the early to mid-twelfth century, Geoffrey of Monmouth wrote a History of the Kings of Britain in Latin, one third of which is devoted to Arthur.  There, again, he is a warrior king who first drives the Saxons out of Britain, and then moves on to conquer most of Europe.  Again, Kay, Bedivere, feature along with his nephew Gawain.  While fighting the Romans, news comes that his wife Guinevere, and his other nephew, Mordred, have betrayed him and claimed the throne and become lovers.  Arthur returns, and he Mordred and Gawain all die in the resulting war.  See the Geoffrey of Monmouth link.

Geoffrey was soon translated into French and soon after a French poet named Chretien de Troyes wrote a series of poems which introduced a new set of tales about the adventures of Arthur's knights.  It was Chretien who introduced Lancelot, a love affair between Lancelot and Guinevere, and the poem of Perceval and the Grail, to the tradition.  The last work was unfinished, and did not involve a grand quest by all Arthur's knights to find the Grail.  See the Chretien de Troyes link.  These were written between 1170 - 1190.

Early in the 13th century, the tradition exploded into a massive compendium now usually referred to as the Lancelot-Grail cycle.  See the What is the Lancelot-Grail? link.  In this, it is important to note that Arthur and Guinevere are already married before Lancelot is born.  (Prose Merlin)  Lancelot and Guinevere fall in love soon after Lancelot arrives at court.  And they are initially helped in their early liaisons by a knight named Galehaut.  (Prose Lancelot Pt 1)  There are hints in the text that Galehaut also loves Lancelot (the only gay element I am aware of), and he dies of grief soon after.  At the end of the cycle, after the Grail quest, you get into the more familiar elements of the tradition.  Lancelot and Guinevere are caught in together just as they are both renouncing their affair for love of Arthur.  Lancelot escapes but she is sentenced to be burnt to death.  Lancelot comes to her rescue but kills Gawain's younger brothers in the process.  Arthur is forced to go to war against Lancelot.  Mordred seizes the throne at home, and, as in Geoffrey, Arthur and Mordred both die fighting each other.  Lancelot arrives to late to help Arthur, and when he eventually dies he is buried beside Galehaut.  Guinevere goes into a nunnery.

Much of this would eventually be translated into English and condensed by Thomas Malory.  And it is Malory's version that most modern writers usually pinch ideas from.

And that's just the simple version.  There were also translations and new tales written in the 13th and 14th centuries in French, English, Welsh, German, Icelandic, Spanish, Italian, and more.
