"studies and confesses one and the same knowledge of the highest truth in the tongues of five nations, namely the Angles, the Britons, the Scots, the Picts, and the Latins", distinguishing between the Brythonic languages of the "ancient Britons" or Old Welsh speakers and other language groups. Brythonic, Saxon and Viking kingdoms such as Strathclyde, Wessex, and Jórvík amalgamated, leading to the formation of Scotland, and England. Wales was sometimes united under princes or kings such as Gruffydd ap Llywelyn. Between 854 and 1171, a kingship of Ireland was established by kings of the regional kingdoms such as Máel Sechnaill mac Máele Ruanaid, Toirdelbach Ua Briain, Muirchertach Mac Lochlainn, and Ruaidrí Ua Conchobair, something not achieved in Britain until 1707. In subsequent Norman Ireland, local lords gained considerable autonomy from the Lordship of Ireland until it became the Kingdom of Ireland under direct English rule. Renaissance mapmakers Abraham Ortelius makes clear his understanding that England, Scotland and Ireland were politically separate in 1570 by the full title of his map: Angliae, Scotiae et Hiberniae, sive Britannicar. insularum descriptio ('A representation of England, Scotland and Ireland, or the Britannic islands'). George Lily's 1546 map divides Britain into the two kingdoms of England and Scotland, with Ireland alongside. Some maps from this period also appear to mark Wales, and sometimes Cornwall, as separate areas within Britain, while the history of England created by Polydore Vergil for Henry VIII states, "The whole country of Britain is divided into four parts, whereof the one is inhabited by Englishmen, the other of Scots, the third Welshmen and the fourth of Cornish people." Maps of the Mediaeval, Renaissance and later periods often referred to Albion. This archaic term was originally used by Ptolemy and Pliny to mean the island of Great Britain. In later centuries its meaning changed to refer only to the area we now call Scotland (Albany, or Alba in Gaelic). Albion has survived as a poetic name for Britain but it is not in everyday use. 18th and 19th centuries Following the Acts of Union 1707, a fashion arose, particularly in Scotland, for referring to Scotland as North Britain, while England was sometimes dubbed South Britain. These terms gained in popularity during the 19th century. The most lasting example of this usage was in the name of the North British Railway, which became part of the London and North Eastern Railway in 1923,
