In Irish mythology, Elcmar or Ecmar (modern spelling: Ealcmhar) is the husband of Boann and belongs to the divine Tuatha Dé Danann.[1] It has been suggested that he is Nuada under another name, and he is sometimes confused with Nechtan, Boann's usual husband.[2] 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. [citation needed] In the Dindsenchas, he is called "lord of horses" and is described as a judge.[3][4] Elcmar is described as having a fork of white hazel, a gold brooch, and a cloak.[5]
