Abstract
The chapter presents two versions of manuscript copies of maps of the Kingdom of Bohemia based on J. Ch.
Müller's works, which are deposited in the Map Collection of the Faculty of Science, Charles University. The first was drawn on 30 rather than 25 handmade paper sheets from Dušníky with an unknown version of St.
Peter filigree. The sizes of the map sections have large deviations.
The map was reduced by 100 mm on both axes. The title cartouche of the large map of Bohemia was not changed, MAPPA GEOGRAPHICA REGNI BOHEMIAE...only differently arranged.
There is a change is in the number of map sections. The map legend copies the original, but with modifications.
The omitted features include a royal city, bishopric, extinct village, ferry, post office, mineral water spring, vineyard and brass, metal wire and soda production. Instead of the post office, the author included postal trails.
Compared to the printed original, which contained forty-eight map symbols, the copy depicts only 39. These facts indicate that the copy may have originated at the end of the 18th century or beginning of the 19th century.
The graphic scale was copied exactly according to the original, although it was changed with new dimensions of the map frame. The scale of the printed original was 1 : 132,000.
The previous scale was calculated as 1 : 137,000. The watercolour painting of the manuscript looks better arranged than the printed original.
There is a division into twelve regions. The water is drawn in agreement with the original, but the blue pigment with werdigris has gone brown.
Pictographic hillocks depicting the altimetry are pea green. The author resigned on the tree symbols.
At the bottom of section XXV, there is a Latin statistic annotation adopted from the land registers dated 1695. In this period, 1615 towns and townships, 700 fortresses, 74,722 villages and 4,309,210 land owners were to be present in the Bohemian Crown Lands.
According to Karel Kuchař, J. Ch.
Müller plotted 12,495 named places. A more recent analysis by J.
Havlíček indicates 14,871 settlement units. The parerga were created by an experienced artist who made masterful variations on Reiner's theme.
The changes are particularly evident in a parergon with personifications of Bohemian rivers with the emblem of Bohemia and the Imperial Eagle. The second described work is an unsigned and undated manuscript copy of a reduced issue of a map of the Kingdom of Bohemia by Johann Wolfgang Wieland from 1726.
The whole work was enlarged by 350 mm on each axis. The name is identical: MAPPA CHOROGRAPHICA...
But only Müller's authorship is attached, Wieland is not mentioned. There is no scale, which indicates the copyist's cartographic knowledge.
The original scale calculation corresponded to 1 : 231,000. The previous scale was calculated as 1 : 184,000.
The underlying material is of poorer quality. Each sheet is damaged and backed with paper.
A new border symbol was added here compared to the original map symbols. However, a fundamental change is the depiction of hills and mountains by means of landscape hatching.
The densest hatches are in section 17, Královský hvozd, in the Bohemian Forest. Symbols of forests are missing.
Provincial roads are drawn as a double red line. Compared to the original, the individual towns of Prague are not described, only the suburbs.
There are also new toponyms such as the Terezín Fortress whose construction began in 1780. New water areas were found in addition to the existing ponds, for example northwest at Solnice or between Jihlava and Havlíčkův Brod.
The borders of regions and their descriptions correspond to Müller's division into twelve regions from 1720. However, the new region structure of 1751 is drawn in sixteen manuscript map sections, though without description.
As regards Kłodzko, which the Kingdom of Bohemia lost in 1742, the coloured border between the County of Kłodzko is no longer indicated. The themes on the parerga are similar to those in the original, but very stiff and artless.
It is supposed that the first manuscript may have emerged in the first half of the 19th century as a work of students in the noble milieu, while the second was very likely a military map where the contents had been regularly supplemented since the mid-18th century and further also after 1782.
