Ogham inscription in the context of "Pictish Stones"

A Pictish stone is a type of monumental stele, generally carved or incised with symbols or designs. A few have ogham inscriptions. Located in Scotland, mostly north of the Clyde-Forth line and on the Eastern side of the country, these stones are the most visible remaining evidence of the Picts and are thought to date from the 6th to 9th century, a period during which the Picts became Christianized. The earlier stones have no parallels from the rest of the British Isles, but the later forms are variations within a wider Insular tradition of monumental stones such as high crosses. About 350 objects classified as Pictish stones have survived, the earlier examples of which holding by far the greatest number of surviving examples of the mysterious symbols, which have long intrigued scholars.

Gaelic Ireland (Irish: Éire Ghaelach) was the Gaelic political and social order, and associated culture, that existed in Ireland from the late prehistoric era until the 17th century. It comprised the whole island before Anglo-Normans conquered parts of Ireland in the 1170s. Thereafter, it comprised that part of the country not under foreign dominion at a given time (i.e. the part beyond The Pale). For most of its history, Gaelic Ireland was a "patchwork" hierarchy of territories ruled by a hierarchy of kings or chiefs, who were chosen or elected through tanistry. Warfare between these territories was common. Traditionally, a powerful ruler was acknowledged as High King of Ireland. Society was made up of clans and, like the rest of Europe, was structured hierarchically according to class. Throughout this period, the economy was mainly pastoral and money was generally not used. A Gaelic Irish style of dress, music, dance, sport and art can be identified, with Irish art later merging with Anglo-Saxon styles to create Insular art.

Gaelic Ireland was initially pagan and had an oral culture maintained by traditional Gaelic storytellers/historians, the seanchaidhthe. Writing, in the form of inscription in the ogham alphabet, began in the protohistoric period, perhaps as early as the 1st century. The conversion to Christianity, beginning in the 5th century, accompanied the introduction of literature. In the Middle Ages, Irish mythology and Brehon law were recorded by Irish monks, albeit partly Christianized. Gaelic Irish monasteries were important centres of learning. Irish missionaries and scholars were influential in western Europe and helped to spread Christianity to much of Britain and parts of mainland Europe.

Primitive Irish or Archaic Irish (Irish: Gaeilge Ársa, Gaeilge Chianach), also called Proto-Goidelic, is the oldest known form of the Goidelic languages, and the ancestor of all languages within this family.

This phase of the language is known only from fragments, mostly personal names, inscribed on stone in the Ogham alphabet in Ireland and western Great Britain between the 4th and the 6th century AD, before the advent of Old Irish. These inscriptions are referred to as Orthodox Ogham, although scholastic use of the script continued residually until the early 19th century.

Rónán, anglicised as Ronan, is an Irish and Breton male given name and surname derived from rón, the Irish word for 'seal'. The given name dates back to Primitive Irish in the form ᚏᚑᚅᚐᚅᚅ  [ᚋᚐᚊ  ᚉᚑᚋᚑᚌᚐᚅᚅ] (RONANN [MAQ COMOGANN]), found as an ogham inscription which translates as 'Rónán, son of Comgán'.

In Irish Mythology, the name is derived from a legend, which tells the story of a mother seal who is warned never to stray too closely to the land. When the seal is swept ashore by a huge wave, she becomes trapped in a human form, known as a "selkie" or "seal maiden". Although she lives as the wife of a fisherman and bears him children, known as "ronans" or "little seals", she never quite loses her "sea-longing". Eventually, she finds the "seal-skin" which the fisherman has hidden and slips back into the ocean. However, she cannot forget her husband and children and can be seen swimming close to the shore, keeping a watchful and loving eye on them.

Byrhtferth (Old English: Byrhtferð; c. 970 – c. 1020) was a priest and monk who lived at Ramsey Abbey in Huntingdonshire (now part of Cambridgeshire) in England. He had a deep impact on the intellectual life of later Anglo-Saxon England and wrote many computistic, hagiographic, and historical works. He was a leading man of science and best known as the author of many different works (although he may not have written many of them). His Manual (Enchiridion), a scientific textbook, is Byrhtferth's best known work.

He studied with Abbo of Fleury, who was invited to Ramsey Abbey by Oswald of Worcester to help teach. Abbo was there during the period 985 to 987, and became a large influence on Byhrtferth who was interested in the same studies, such as history, logic, astronomy, and mathematics. We do not have contemporary biographies of Byrhtferth, and the only information we have is that given in his Manual and his Preface.
