Elcmar

In Irish mythology, Elcmar or Ecmar (modern spelling: Ealcmhar) is the husband of Boann and belongs to the divine Tuatha Dé Danann. It has been suggested that he is Nuada under another name, and he is sometimes confused with Nechtan, Boann's usual husband. At first glance he appears to be associated with horses but there is also a school of thought that says his name means The Evil One. In the Dindsenchas, he is called "lord of horses" and is described as a judge. Elcmar is described as having a fork of white hazel, a gold brooch, and a cloak.
