Information: - The Adriatic Sea is a body of water separating the Italian Peninsula from the Balkan peninsula and the Apennine Mountains from the Dinaric Alps and adjacent ranges. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Greece, Italy, Montenegro and Slovenia. The Adriatic contains over 1,300 islands, mostly located along its eastern, Croatian, coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The Otranto Sill, an underwater ridge, is located at the border between the Adriatic and Ionian Seas. The prevailing currents flow counterclockwise from the Strait of Otranto, along the eastern coast and back to the strait along the western (Italian) coast. Tidal movements in the Adriatic are slight, although larger amplitudes are known to occur occasionally. The Adriatic's salinity is lower than the Mediterranean's because the Adriatic collects a third of the fresh water flowing into the Mediterranean, acting as a dilution basin. The surface water temperatures generally range from in summer to in winter, significantly moderating the Adriatic Basin's climate. - Bari (Bari dialect: Bare; "Barion") is the capital city of the Metropolitan City of Bari and of the Apulia region, on the Adriatic Sea, in Italy. It is the second most important economic centre of mainland Southern Italy after Naples, and is well known as a port and university city, as well as the city of Saint Nicholas. The city itself has a population of about 326,799, , over , while the urban area counts 653,028 inhabitants over . The metropolitan area counts 1.3 million inhabitants. - A university ("a whole", "a corporation") is an institution of higher (or tertiary) education and research which grants academic degrees in various subjects. Universities typically provide undergraduate education and postgraduate education. - A port is a location on a coast or shore containing one or more harbors where ships can dock and transfer people or cargo to or from land. Port locations are selected to optimize access to land and navigable water, for commercial demand, and for shelter from wind and waves. Ports with deeper water are rarer, but can handle larger ships. Since ports throughout history handled every kind of traffic, support and storage facilities vary widely, may extend for miles, and dominate the local economy. Some ports have an important military role. - Lupus Protospatharius Barensis was the reputed author of the Chronicon rerum in regno Neapolitano gestarum ( also called Annales Lupi Protospatharii ) , a precise history of the Mezzogiorno from 805 to 1102 . He has only been named as the author since the seventeenth century . Lupus , along with two other Bariot chronicles , the Annales barenses and the Anonymi barensis chronicon , used some lost ancient annals of Bari up to 1051 . William of Apulia appears to have used these same annals . Lupus also used the lost annals of Matera . Perhaps most unusual to Lupus is his dating method . He began his years in September and so places events of the latter half of a given year in the next year . - The Normans (Norman: "Nourmands"; ) were the people who, in the 10th and 11th centuries, gave their name to Normandy, a region in France. They were descended from Norse ("Norman" comes from "Norseman") raiders and pirates from Denmark, Iceland and Norway who, under their leader Rollo, agreed to swear fealty to King Charles III of West Francia. Through generations of assimilation and mixing with the native Frankish and Gallo-Roman populations, their descendants would gradually adopt the Carolingian-based cultures of West Francia, ultimately resulting in their own assimilation into the Romance society. The distinct cultural and ethnic identity of the Normans emerged initially in the first half of the 10th century, and it continued to evolve over the succeeding centuries. - William of Apulia was a chronicler of the Normans, writing in the 1090s. His Latin epic, Gesta Roberti Wiscardi ("The Deeds of Robert Guiscard"), written in hexameters, is one of the principal contemporary sources for the Norman conquest of southern Italy, especially the career of Robert Guiscard, Duke of Apulia (10591085). - Basilicata (or ), also known as Lucania, is a region in the south of Italy, bordering on Campania to the west, Apulia ("Puglia") to the north and east, and Calabria to the south. It also has two coastlines, one on the Tyrrhenian Sea between Campania and Calabria, and a longer coastline along the Gulf of Taranto between Calabria and Apulia. The region can be thought of as the "instep" of Italy, with Calabria functioning as the "toe" and Apulia the "heel". The region covers about and in 2010 had a population slightly under 600,000. The regional capital is Potenza. The region is divided into two provinces: Potenza and Matera. The president of Basilicata is Marcello Pittella. - Matera (or locally ) is a city and a province in the region of Basilicata, in Southern Italy. It is the capital of the province of Matera and the capital of Basilicata from 1663 to 1806. The town lies in a small canyon carved out by the Gravina. - Robert Guiscard ( 17 July 1085) was a Norman adventurer remembered for the conquest of southern Italy and Sicily. Robert was born into the Hauteville family in Normandy, went on to become Count of Apulia and Calabria (10571059), and then Duke of Apulia and Calabria and Duke of Sicily (10591085). - Saint Nicholas; (15 March 270 6 December 343), also called Nikolaos of Myra, was a historic 4th-century Christian saint and Greek Bishop of Myra, in Asia Minor (modern-day Demre, Turkey). Because of the many miracles attributed to his intercession, he is also known as Nikolaos the Wonderworker. His reputation evolved among the faithful, as was common for early Christian saints, and his legendary habit of secret gift-giving gave rise to the traditional model of Santa Claus through Sinterklaas. - Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City. Italy covers an area of and has a largely temperate seasonal climate and Mediterranean climate; due to its shape, it is often referred to in Italy as "lo Stivale" (the Boot). With 61 million inhabitants, it is the fourth most populous EU member state. Given the paragraphs above, decide what entity has the relation 'occupation' with 'chronicler'.
