King Lot

Lot is the king of Lothian, the realm of the Picts in the Arthurian legend. Such a ruler first appeared late in the 1st millennium's hagiographical material concerning Saint Kentigern (also known as Saint Mungo), which feature a Leudonus, king of Leudonia, a Latin name for Lothian. In the 12th century, Geoffrey of Monmouth adapted this to Lot, king of Lothian, in his influential chronicle Historia Regum Britanniae, portraying him as King Arthur's brother-in-law and ally. In the wake of Geoffrey's writings, Lot appeared regularly in later works of chivalric romance.

Lot chiefly figures as king of Lothian, but in other sources he also rules Orkney and sometimes Norway. He is generally depicted as the husband of Arthur's sister or half-sister, often known as Anna or Morgause. The names and number of his children vary depending on the source, but the later romance tradition gives him the sons Gawain, Agravain, Gaheris, Gareth, and Mordred. …more
