 Passage 2:The history of the county of Portugal is traditionally dated from the reconquest of Portus Cale (Porto) by Vímara Peres in 868. He was named a count and given control of the frontier region between the Limia and Douro rivers by Alfonso III of Asturias. South of the Douro, another border county would be formed decades later when what would become the County of Coimbra was conquered from the Moors by Hermenegildo Guterres. This moved the frontier away from the southern bounds of the county of Portugal, but it was still subject to repeated campaigns from the Caliphate of Córdoba. The recapture of Coimbra by Almanzor in 987 again placed the County of Portugal on the southern frontier of the Leonese state for most of the rest of the first county's existence. The regions to its south were only again conquered in the reign of Ferdinand I of León and Castile, with Lamego falling in 1057, Viseu in 1058 and finally Coimbra in 1064.
 Passage 3:Chung was born in 1950 in Kingston, Jamaica. He worked as a session keyboard player and guitarist in the 1960s, as a member of The Mighty Mystics and the Now Generation Band, both of which also included his brother, guitarist Mikey Chung, and Lee "Scratch" Perry's band The Upsetters, among others. He began working as a producer in the 1970s, initially with Sharon Forrester on her debut album, and set up his Edge productions company in 1974. His productions included work by The Abyssinians, The Heptones, and Marcia Griffiths. He also worked with Ras Michael's Sons of Negus band, on the 1975 album Rastafari Dub, playing synthesizer, organ and piano, and worked regularly with singer Pablo Moses, both as keyboard player and producer, including his first and best-known recording "I Man a Grasshopper". Chung also produced the recordings that would be released as the first two albums from Ijahman Levi. In the early 1980s he became resident engineer at the Dynamic studios, where he mixed several albums by Peter Tosh, and he co-produced early recordings by Frankie Paul. In the late 1980s he relocated to Miami, where he established his own recording studio. In 1991 he produced and engineered Maxi Priest's Best of Me album. Geoffrey died in November 1995 of liver failure. Geoffrey's work continues to be released since his death such as the 2003 release of Everton Blender's King Man album where he played clavinet and acted as engineer.
