In 1967 Louis le Brocquy was commissioned by the publisher Liam Miller to illustrate Thomas Kinsella's inspired version of the Táin Bó Cúailnge, the dramatic record of Ireland's proto-historic past.
 Ailbhe Ní Bhriain remarks: 'The Táin Bó Cuailnge - táin, meaning the gathering of people for a cattle raid - is a prose epic with verse passages and forms the centrepiece of the cycle of Ulster heroic stories.
 It tells of the exploits of King Conchobar and his chief warrior Cúchulainn ("The Hound of Ulster") and of the invasion of Ulster by Queen Medb of Connacht in an attempt to capture the Brown Bull of Cuailgne.
 Dating as far back as the 12th century in manuscript form, this legend has been treated both academically by scholars and linguists and romantically by such Revival writers as Yeats and Lady Gregory.
 The Dolmen Edition of the saga was to give, in Kinsella's words, the first "living version of the story", a version true to its blunt and brutal Gaelic character.'
 Louis le Brocquy paints several hundred calligraphic brush drawings over a period of six months retaining 133 illustrations.
 The artist will note: 'Any graphic accompaniment to a story which owes its existence to the memory and concern of a people over some twelve hundred years, should decently be as impersonal as possible.
 The illustrations of early Celtic manuscripts express not personality but temperament.
 They provide not graphic comment on the text but an extension of it.
 Their means are not available to us today - either temperamentally or technically - but certain lessons may be learned from them relevant to the present work.
 In particular they suggest that graphic images, if any, should grow spontaneously and even physically from the matter of the printed text.
 If these images - these marks in printer's ink - form an extension to Thomas Kinsella's Táin, they are a humble one.
 It is as shadows thrown by the text that they derive their substance.'
Findabair or Finnabair (modern Irish Fionnabhair ] ) was a daughter of Ailill and Queen Medb of Connacht in Irish mythology.
 The meaning of the name is "white phantom" (etymologically cognate with "Gwenhwyfar", the original Welsh form of Guinevere).
 The Dindsenchas also mention a Findabair that is the daughter of Lugaid Laigde.
Táin Bó Cúailnge (] ; "the driving-off of cows of Cooley", commonly known as The Cattle Raid of Cooley or The Táin) is a legendary tale from early Irish literature, often considered an epic, although it is written primarily in prose rather than verse.
 It tells of a war against Ulster by the Connacht queen Medb and her husband Ailill, who intend to steal the stud bull Donn Cuailnge, opposed only by the teenage Ulster hero Cú Chulainn.
Fergus mac Róich (son of "Ró-ech" or "great horse"; also mac Róig, mac Rossa) is a character of the Ulster Cycle of Irish mythology.
 Formerly the king of Ulster, he is tricked out of the kingship and betrayed by Conchobar mac Nessa, and becomes the ally and lover of Conchobar's enemy queen Medb of Connacht, and joins her expedition against Ulster in the "Táin Bó Cúailnge".
 The name "Fergus" (later Irish "Fearghus") means "man-strength" or "virility", and Fergus is described as being of enormous size and sexual potency.
 This leads him into many a precarious situation as in the story of the Táin Bó Flidhais.
Maigh Seóla (] ) was the territory that included land along the east shore of Lough Corrib in County Galway, Ireland.
 It was bounded by the Uí Maine vassal kingdom of Soghain.
 Its rulers up to the 1220s were the Muintir Murchada, who took the surname O'Flaherty.
 They were based at Loch Cime (later called Lough Hackett) until forced west of Lough Corrib during the de Burgo led English invasion of Connacht in the 13th century.
 According to the 17th century historian Ruaidhrí Ó Flaithbheartaigh Maigh Seóla was considered part of Iar Connacht prior to the 13th century Anglo-Norman invasion of Connacht.
 After the de Burgo / Burke family became established in Maigh Seola the territorial term Iar Connacht was only used to denote the territory of the O'Flahertys west of Lough Corrib and Lough Mask.
Medb (pronounced ] )—later spelled Meadhbh (] ) and Méabh (] )—is queen of Connacht in the Ulster Cycle of Irish mythology.
 Her husband in the core stories of the cycle is Ailill mac Máta, although she had several husbands before him who were also kings of Connacht.
 She rules from Cruachan (now Rathcroghan, County Roscommon).
 She is the enemy (and former wife) of Conchobar mac Nessa, king of Ulster, and is best known for starting the "Táin Bó Cúailnge" ("The Cattle Raid of Cooley") to steal Ulster's prize stud bull.
 Medb is strong-willed, ambitious, cunning and promiscuous, and is an archetypal warrior queen.
 She is believed to be a manifestation of the sovereignty goddess.
 Medb of Connacht is probably identical with Medb Lethderg, the sovereignty goddess of Tara, and may also be linked with the Morrígan.
Queen Medb of Connacht had discovered that her husband, Ailill, was richer than her to the tune of one extremely fertile stud bull, and resolved to even the account by possessing Dáire's great bull.
 She sent messengers to Dáire with an extremely generous offer of land and treasure, and if necessary sexual favours, if he would loan the bull to her for a year.
 Dáire agreed.
 However the messengers got drunk, and one boasted that if he had not agreed Medb would have taken the bull by force.
 When Dáire heard that he backed out of the deal, and Medb did indeed take the bull by force.
Eochu or Eochaid Feidlech ("the enduring"), son of Finn, son of Rogen Ruad, son of Essamain Emna, son of Blathnachta, son of Labraid Lorc, son of Enna Aignech was, according to medieval Irish legends and historical traditions, a High King of Ireland.
 He is best known as the father of the legendary queen Medb of Connacht.
