In the book, it says:
"Charles BridgeAmong the best-known architectural features of Prague is Charles Bridge (Karl¿v most). Known as PragueBridge until 1870, it spans the Vltava River and the Kampa Island between the Lesser Town and the OldTown. It is one of the oldest stone bridges in Europe and the second oldest in the republic (the oldest inPísek, Bohemia, was built in the thirteenth century).The first bridge crossing the Vltava in Prague was wooden anddated from the tenth century. The Judith stone bridge, built 1158–1160, spanned the river until a disastrous floodwashed it away in 1342. Charles IV commissioned Petr Parlérˇ to erect a new bridge; being somewhat superstitious,the king broke ground for the bridge in 1357 on 9 July at 5:31 A.M., thus creating a date and time that, if given com-pletely in numbers, is a perfect palindrome: 1–3–5–7–9–7–5–3–1.
The sandstone bridge, stretching 516 meters with sixteen arches, was completed in 1402.Thirty statues adorn thebridge (the originals for most are in the Lapidarium of the National Museum). In 1683 Charles Bridge received itsfirst baroque sculpture, that of St. John Nepomuk, the work of Matthias Rauchmüller and Jan Brokoff. The bronzerelief at the base of the statue depicts the false legend that Jan Nepomuk would not tell Václav IV the secrets of thequeen’s confession, so Václav IV had him cast into the Vltava from the bridge (a bronze cross in the bridge parapetmarks the alleged spot). Other baroque masters who sculpted works for the bridge included Ferdinand MaximiliánBrokoff, Michal Josef Brokoff, and Matyá≥Bernard Braun. In the classical era, Josef Max, Emanuel Max, and otherssculpted several statues. Karel Dvorˇák completed the most recent statue, that of the missionaries Cyril and Method-ius, in 1938.
On the Lesser Town side of the bridge are two towers.The first is a remnant of the Judith Bridge that was rebuiltin 1591. The taller Gothic tower was completed in 1464, and a Gothic gateway links the two towers. On the OldTown side of the bridge stands a single Gothic tower decorated with saints, the builders, and skillfully executed rep-resentations of Charles IV and his son,Václav IV. Also embellishing the tower are the coats of arms of the Bohemiankingdom.The roof is the design of Josef Mocker from the late nineteenth century. A portion of the Old Town Towerfacade and the bridge was damaged during a Swedish bombardment in 1648."
Ok - so now, I can see where the wiki claim is from. But, where is this source in the history book from?
My problem is that this is presented as true, but I want to know where the sources are. The book "EASTERN EUROPE" by RICHARD FRUCHT, was written in 2005. Obviously we are not dealing with a primary or secondary source. But what is the source Frucht is using? Is it just a story Frucht or someone else made up? We don't know.
