Tighearnmhas Masius, High King of Ireland {Legendary}

   Tigernmas was the 13th Monarch, and reigned 77 years; according to Keating, he reigned but 50 years; he fought twenty-seven battles with the followers of the family of Heber Fionn, all which he gained. In his reign gold was mined near the Liffey, and skilfully worked by Inchadhan. 

This King also made a law that each grade of society should be known by the number of colours in its wearing apparel. The clothes of a slave should be of one colour; those of a soldier of two; the dress of a commanding officer to be of three colours; a gentleman's dress, who kept a table for the free entertainment of strangers, to be of four colours; five colours to be allowed to the nobility, the chiefs, and the King, Queen, and Royal Family, as well as the Druids, historians, and other learned men to wear six colours.
Tigernmas died B.C. 1543, on the Eve of 1st of November, with two-thirds of the people of Ireland, at Magh Sleaght (or Field of Adoration), in the county of Leitrim, as he was adoring the Sun-God, Crom Cruach (a quo Macroom). Historians say this Monarch was the first who introduced image worship in Ireland.

Misc. Notes

Tigernmas (or Tiernmas) : This Tiernmas was the Monarch who set up tbe famous idol called "Crom Cruach" (literally, the crooked heap) on the plain of Magh Sleaght, now Fenagh, in the barony of Mohill, county of Leitrim. This idol was, worshipped up to the time of St. Patrick, by whom it was destroyed. Among the idol-worship of the ancient Irish at that time was that of the sun: the sun-woiship which was that of the Magi or wise men of the East, who, we are told in Scripture, were led to Bethlehem by divine inspiration to see the Infant Jesus.

This Monarch introduced certain distinctions in rank among the Irish, which were indicated by the wearing of certain colours, which, by some persons, is believed to have been the origin of the Scotch plaid. According to Keatinge, one colour was used in the dress of a slave ; two colours in that of a plebeian; three, in that of a soldier or young lord; four, in that of a brughaidh or public victualler; five, in that of a lord of a tuath or cantred ; and six colours in that of an ollamh or chief professor of any of the liberal arts, and in that of the king and queen. —BOOK OF RIGHTS.
