Question: How many times did plague occur in the birth city of the composer of Nulla in mundo pax sincera?

the number zero does not have its own roman numeral, but the word nulla (the latin word meaning ``none '') was used by medieval scholars in lieu of 0. dionysius exiguus was known to use nulla alongside roman numerals in 525. about 725, bede or one of his colleagues used the letter n, the initial of nulla or of nihil (the latin word for`` nothing''), in a table of epacts, all written in roman numerals. <SEP> It is a recomposition of an "Orlando furioso" written by Giovanni Alberto Ristori which had been very successfully staged by Vivaldi and his father's "impresa" in 1713, and whose music survives in a few fragments retained in the score of RV 819. Therefore, Vivaldi's first cataloguer Peter Ryom did not assign the opera a RV number, but catalogued it as RV Anh. 84. Orlando furioso RV 819 (, Teatro San Angelo, Venice 1714) is a three-act opera surviving in manuscript in Antonio Vivaldi's personal library, only partly related to his better known Orlando furioso (RV 728) of 1727. The libretto was by Grazio Braccioli. <SEP> Written in the key of E major and in the typical lyrical Italian Baroque style, it is scored for solo soprano, two violins, viola and basso continuo, this would normally be a cello and keyboard instrument, in Vivaldi's case often the organ. Nulla in mundo pax sincera, RV 630, is a sacred motet composed by Antonio Vivaldi in 1735 to an anonymous Latin text, the title of which may be translated as "In this world there is no honest peace" or "There is no true peace in this world without bitterness". The text dwells on the imperfections of a world full of evil and sin, and praises Jesus for the salvation he offers from it. It is considered to be one of Vivaldi's most beautiful solo motets. <SEP> the denmark place fire occurred on 16 august 1980 at 18 denmark place in central london, united kingdom. the fire, caused by arson, killed 37 people of eight different nationalities, most of whom were spanish or latin american, who were patrons of two unlicensed bars in the building. at the time, "the sunday times" suggested that it could be "the worst mass murder in british history". <SEP> In 1466, perhaps 40,000 people died of the plague in Paris. Plague occurred in Venice 22 times between 1361 and 1528. During the 16th and 17th centuries, the plague was present in Paris around 30 per cent of the time. The Black Death ravaged Europe for three years before it continued on into Russia, where the disease was present somewhere in the country 25 times between 1350 to 1490. Plague epidemics ravaged London in 1563, 1593, 1603, 1625, 1636, and 1665, reducing its population by 10 to 30% during those years. Over 10% of Amsterdam's population died in 1623–25, and again in 1635–36, 1655, and 1664. The plague of 1576–77 killed 50,000 in Venice, almost a third of the population. Late outbreaks in central Europe included the Italian Plague of 1629–1631, which is associated with troop movements during the Thirty Years' War, and the Great Plague of Vienna in 1679. Over 60% of Norway's population died in 1348–50. The last plague outbreak ravaged Oslo in 1654.
