Vistula - about the name
The name was first recorded by Pomponius Mela in a.d. 40 and by Pliny in a.d. 77 in his Natural History. Mela names the river Vistula (3.33), Pliny uses Vistla (4.81, 4.97, 4.100). The root of the name Vistula is Indo-European *u?eis- ?to ooze, flow slowly? (cf. Sanskrit ?????? / ave?an ?they flowed?, Old Norse veisa ?slime?) and is found in many European rivernames (e.g. Weser, Viesinta).2 The diminutive endings -ila, -ula, were used in many Indo-European languages, including Latin (see Ursula).
In writing about the Vistula River and its peoples, Ptolemy uses the Greek spelling Ouistoula. Other ancient sources spell it Istula. Ammianus Marcellinus refers to the Bisula (Book 22), note the lack the -t-. Jordanes (Getica 5 & 17) uses Viscla while the Anglo-Saxon poem Widsith refers to it as the Wistla.3 12th-century Polish chronicler Wincenty Kadłubek Latinised the rivername as Vandalus, a form presumably influenced by Lithuanian vandu? ?water?, while Jan Długosz in his Annales seu cronicae incliti regni Poloniae called the Vistula ?white waters? (Alba aqua), perhaps referring to the White Little Vistula (Biała Wisełka): ?a nationibus orientalibus Polonis vicinis, ob aquae candorem Alba aqua ... nominatur.?
Abou climate in Cracow
Kraków has an oceanic climate (Cfb) according to the Köppen climate classification system, one of the easternmost localities in Europe to do so. A mere 100 km (62 mi) north-east of Kraków (east of Tarnów, and north of Kielce), the January mean dips below ?3 °C (27 °F) and thus becomes continental (Dfb) in nature. The Kraków climate is also influenced by its far inland position, with significant temperature differences between seasons. Average temperatures in summer range from 18 to 19.6 °C (64 to 67 °F) and in winter from ?2.0 to ?0.6 °C (28 to 31 °F). The average annual temperature is 8.7 °C (48 °F). In summer temperatures often exceed 25 °C (77 °F), and even 30 °C (86 °F), while winter drops to ?5 °C (23 °F) at night and about 0 °C (32 °F) at day; during very cold nights the temperature can drop to ?15 °C (5 °F). Since Kraków lies near the Tatra Mountains, there are often occurrences of halny blowing (a foehn wind), causing temperatures to rise rapidly, and even in winter reach up to 20 °C (68 °F).
Golden Age and Cracow
The 15th and 16th centuries were known as Poland's Złoty Wiek or Golden Age. Many works of Polish Renaissance art and architecture were created, including ancient synagogues in Kraków's Jewish quarter located in the north-eastern part of Kazimierz, such as the Old Synagogue. During the reign of Casimir IV, various artists came to work and live in Kraków, and Johann Haller established a printing press in the city after Kasper Straube had printed the Calendarium Cracoviense, the first work printed in Poland, in 1473.
In 1520, the most famous church bell in Poland, named Zygmunt after Sigismund I of Poland, was cast by Hans Behem. At that time, Hans Dürer, a younger brother of artist and thinker Albrecht Dürer, was Sigismund's court painter. Hans von Kulmbach made altarpieces for several churches. In 1553, the Kazimierz district council gave the Jewish Qahal a licence for the right to build their own interior walls across the western section of the already existing defensive walls. The walls were expanded again in 1608 due to the growth of the community and influx of Jews from Bohemia. In 1572, King Sigismund II, the last of the Jagiellons, died childless. The Polish throne passed to Henry III of France and then to other foreign-based rulers in rapid succession, causing a decline in the city's importance that was worsened by pillaging during the Swedish invasion and by an outbreak of bubonic plague that left 20,000 of the city's residents dead. In 1596, Sigismund III of the Swedish House of Vasa moved the administrative capital of the Polish?Lithuanian Commonwealth from Kraków to Warsaw
