1. Overview
Rinnal (also known as Rindal, Rionnal, or Rinnan; Rinnal, RionnalRinnal, RionnalIrish RindalRindalIrish RinnanRinnanIrish) is a mythological figure in Irish mythology who served as a High King of Ireland. He belonged to the Fir Bolg, an ancient race believed to have settled in Ireland. The narrative of Rinnal, including his ascent to power, his notable innovation, and his eventual downfall, offers valuable insights into the mythological construction of early Irish society, particularly concerning leadership, technological advancement, and the cyclical nature of power shifts. His story highlights the transformative impact of new tools and the inherent instability of ancient monarchies, resonating with broader themes of social evolution and political change.
2. Background and Lineage
Rinnal's ancestry places him firmly within the lineage of the Fir Bolg, one of the early groups to inhabit Ireland in Irish mythological tradition. His father was Genann, a prominent figure within the Fir Bolg. The narrative extends Rinnal's family line through his descendants, including his son, Erce, and his grandson, Ohad. This lineage underscores Rinnal's deep roots within the mythological framework of ancient Ireland, connecting him to a broader network of figures that shaped the mythical history of the land.

3. Reign as High King of Ireland
Rinnal ascended to the position of High King of Ireland after successfully overthrowing Fiacha Cennfinnán. His reign is particularly noted for a significant innovation: he is traditionally credited as the first king in Ireland to utilize spearheads. This detail is notable, reflecting a potential mythological acknowledgment of advancements in weaponry or martial technology. The term "spearhead" itself has linguistic roots in Old Irish, where "rind" (rind) or "rinn" (rinn) refers to a "(spear-)point" or "(spear)tip," emphasizing the direct connection between his name and this technological development. Such an introduction would have fundamentally altered the dynamics of warfare and hunting, leading to profound societal implications for defense, resource acquisition, and the balance of power.
Rinnal's tenure as High King lasted for a period of either five or six years, with specific ancient sources offering varying timelines for his rule. The Annals of the Four Masters suggest his reign occurred between 1917 BC and 1911 BC, while Geoffrey Keating's Foras Feasa ar Érinn places it later, from 1497 BC to 1491 BC. Despite his innovation, Rinnal's rule was brought to an end when he was overthrown by his cousin, Fodbgen, who was the son of Sengann. This act of deposition by a close family member highlights the recurrent theme of internal power struggles and dynastic shifts within early Irish mythological narratives.
