Quote #4
“This nyght ye shalle lye with Igrayne in the castel of Tyntagyll; and ye shalle be lyke the duke her husband.” (5.8-9)

Arthur is conceived when Uther swaps identities with Igrayne’s husband, Gorlois – the duke. Of course this disguise makes Arthur’s right to the throne all the more confusing. Who is going to believe that this illegitimate child with a murky history can legitimately be King of England? Not the alliance of Northern Kings, that much is sure.
