Question: The volcano, named after the legendary King featured in Historia Regum Britanniae, last erupted when?

title: Scottish Parliament
text: The election produced a majority SNP government, making this the first time in the Scottish Parliament where a party has commanded a parliamentary majority. The SNP took 16 seats from Labour, with many of their key figures not returned to parliament, although Labour leader Iain Gray retained East Lothian by 151 votes. The SNP took a further eight seats from the Liberal Democrats and one seat from the Conservatives. The SNP overall majority meant that there was sufficient support in the Scottish Parliament to hold a referendum on Scottish independence.

title: 2008 Triglav Trophy
text: The 2008 Triglav Trophy was the Triglav Trophy figure skating competition of the 2007–08 figure skating season. The competition is always held annually in the spring in Jesenice, Slovenia. Due to its timing, the Triglav Trophy is usually the last or one of the last International Skating Union-sanctioned international competitions of the season.

title: The Strange Case of Peter the Lett
text: The Strange Case of Peter the Lett (1931) (), a detective novel by the Belgian writer Georges Simenon, is the very first novel to feature Inspector Jules Maigret who would later feature in more than a hundred stories by Simenon and who has become a legendary figure in the annals of detective fiction.

title: Arthur's Seat
text: Like the rock on which Edinburgh Castle is built, it was formed by an extinct volcano system of Carboniferous age (lava samples have been dated at 341 to 335 million years old), which was eroded by a glacier moving from west to east during the Quaternary (approximately the last two million years), exposing rocky crags to the west and leaving a tail of material swept to the east. This is how the Salisbury Crags formed and became basalt cliffs between Arthur's Seat and the city centre. From some angles, Arthur's Seat resembles a lion couchant. Two of the several extinct vents make up the 'Lion's Head' and the 'Lion's Haunch'.

title: Pharaoh Dome
text: Pharaoh Dome is a lava dome in northwestern British Columbia, Canada, located near Mount Edziza in Mount Edziza Provincial Park. It last erupted during the Pleistocene epoch.

title: Yellowstone Caldera
text: The caldera formed during the last of three supereruptions over the past 2.1 million years: the Huckleberry Ridge eruption 2.1 million years ago (which created the Island Park Caldera and the Huckleberry Ridge Tuff); the Mesa Falls eruption 1.3 million years ago (which created the Henry's Fork Caldera and the Mesa Falls Tuff); and the Lava Creek eruption approximately 630,000 years ago (which created the Yellowstone Caldera and the Lava Creek Tuff).

title: Historic eruptions of Mount Fuji
text: Sixteen eruptions of New Fuji have been recorded since 781. Many of the eruptions occurred in the Heian era, with twelve eruptions between 800 and 1083. Sometimes inactive periods between eruptions lasted for hundreds of years, as in the period between 1083 and 1511, when no eruptions were recorded for over 400 years. At present, there have been no eruptions since the Hoei eruption in 1707 -- 1708, around 300 years ago.

title: Santorini
text: Post-Minoan eruptive activity is concentrated on the Kameni islands, in the centre of the lagoon. They have been formed since the Minoan eruption, and the first of them broke the surface of the sea in 197 BC Nine subaerial eruptions are recorded in the historical record since that time, with the most recent ending in 1950.

title: King Arthur
text: The historical basis for the King Arthur legend has long been debated by scholars. One school of thought, citing entries in the Historia Brittonum (History of the Britons) and Annales Cambriae (Welsh Annals), sees Arthur as a genuine historical figure, a Romano - British leader who fought against the invading Anglo - Saxons some time in the late 5th to early 6th century. The Historia Brittonum, a 9th - century Latin historical compilation attributed in some late manuscripts to a Welsh cleric called Nennius, contains the first datable mention of King Arthur, listing twelve battles that Arthur fought. These culminate in the Battle of Badon, where he is said to have single - handedly killed 960 men. Recent studies, however, question the reliability of the Historia Brittonum.

title: Volcano
text: Scientists usually consider a volcano to be erupting or likely to erupt if it is currently erupting, or showing signs of unrest such as unusual earthquake activity or significant new gas emissions. Most scientists consider a volcano active if it has erupted in the last 10,000 years (Holocene times) -- the Smithsonian Global Volcanism Program uses this definition of active. Most volcanoes are situated on the Pacific Ring of Fire. An estimated 500 million people live near active volcanoes.

title: Mount Hood
text: The last three eruptions at Mount Hood occurred within the past 1,800 years from vents high on the southwest flank and produced deposits that were distributed primarily to the south and west along the Sandy and Zigzag rivers. The last eruptive period took place around 220 to 170 years ago, when dacitic lava domes, pyroclastic flows and mudflows were produced without major explosive eruptions. The prominent Crater Rock just below the summit is hypothesized to be the remains of one of these now - eroded domes. This period includes the last major eruption of 1781 to 1782 with a slightly more recent episode ending shortly before the arrival of the explorers Lewis and Clark in 1805. The latest minor eruptive event occurred in August 1907.

title: Middle Ages
text: Chivalry and the ethos of courtly love developed in royal and noble courts. This culture was expressed in the vernacular languages rather than Latin, and comprised poems, stories, legends, and popular songs spread by troubadours, or wandering minstrels. Often the stories were written down in the chansons de geste, or "songs of great deeds", such as The Song of Roland or The Song of Hildebrand. Secular and religious histories were also produced. Geoffrey of Monmouth (d. c. 1155) composed his Historia Regum Britanniae, a collection of stories and legends about Arthur. Other works were more clearly history, such as Otto von Freising's (d. 1158) Gesta Friderici Imperatoris detailing the deeds of Emperor Frederick Barbarossa, or William of Malmesbury's (d. c. 1143) Gesta Regum on the kings of England.

title: Great Britain
text: After the Anglo - Saxon period, Britain was used as a historical term only. Geoffrey of Monmouth in his pseudohistorical Historia Regum Britanniae (c. 1136) refers to the island as Britannia major (``Greater Britain ''), to distinguish it from Britannia minor (`` Lesser Britain''), the continental region which approximates to modern Brittany, which had been settled in the fifth and sixth centuries by migrants from Britain. The term Great Britain was first used officially in 1474, in the instrument drawing up the proposal for a marriage between Cecily the daughter of Edward IV of England, and James the son of James III of Scotland, which described it as ``this Nobill Isle, callit Gret Britanee ''. It was used again in 1604, when King James VI and I styled himself`` King of Great Brittaine, France and Ireland''.

title: Catellus
text: Catellus: Catellus () was a legendary king of the Britons, as recounted in Geoffrey of Monmouth's work "Historia Regum Britanniae". According to Geoffrey, he was the son of King Gerennus and was succeeded by his son, Millus. In some versions of the "Brut y Brenhinedd", a series of Welsh versions of Geoffrey's "Historia", Catellus is succeeded by his son Coel, who is then succeeded by his own son Porrex II.
