About Gaodhal Glas .
Father: Niul Prince of Scythia
Gaodhal (or Gathelus), the son of Niul, and ancestor of Clan-na-Gael, that is, "the children or descendants of Gaodhal". In his youth this Gaodhal was stung in the neck by a serpent whence followed the word "Glas" to be added to his named, as Gaodhal Glas (glas: Irish, green; Lat. glaucus; Gr. glaukos), on account of the green scar which the word signifies, and which, during his life, remained on his neck after the wound was healed. And Gaodhal obtained a further blessing, namely—that no venemous beast can liv3e any time where his posterity should inhabit; which is verified in Creta or Candia, Gothia or Getulia, Ireland, etc. The Irish chroniclers arrifm that from this tiem Gaodhal and his posterity did paint the figures of Beasts, Birds, etc., on their banners and shields, to distinguish their tribes and septs, in imitation of the Israelites; and that a "Thunderbolt" was the cognizance in their chief standard for many generations after this Gaodhal.

Bitten by a serpent while he & his father were at the Hebrew Camp, but was immediately cured by being touched by the 'Rod of Moses'. Moses prophesied that no venomous creature should ever live in any place where the posterity of Gaodhal should settle & that they should be the Patrons of all learning. In return for this kindness, Gaodhal & his father supplied the Israelites with provisions for their journey. The Gaels are named after him. He was born during the time period when his father was teaching the sciences & the various languages to the youths of Egypt. He & his mother moved to the area of Campus Circit after the death of his father.
