18th century organ prospects in Lithuania: compiled or original

Organ construction art in Lithuania took a rapid development pace from the middle of the 18th century when a few German masters of organs came to Vilnius. Each of them brought knowledge about organs acquired in different workshops. Brought traditions, requirements of customers, and local artistic traditions formed the style of Vilnius organs which then developed into Vilnius Organ School. Its foundator is considered a master of organs A. G. Zelle. He introduced Konigsberg organ school in Lithuania. From 1752, he employed as apprentice N. Jantzon, who later became one of the best masters of organs of the 2nd haft of the 18th century. His prospects reflect traditions not only of Konigsberg school, but also compositional mixtures of the organ prospects of Hamburg. In the prospects of the other master of organs of Vilnius J. F. Scheeli, the influence of any certain country can hardly be defined. The architectural composition of his prospects consists of two tall rounded side towers, triangular shaped central tower, and the flat plains of intermediate windows; this composition may be called the early Vilnius organ prospect form. It was used by the most of masters in the 2nd half of the 18th century. Eventually, the composition was slightly modified: it became narrower and more extensive, side towers became multi-angular and the central one became round. By adding side windows, the form of the organs of medium prospect was formed. Such type of prospects of Baroque organs was dominant in Samogitia even till 1810s. The compositional type of large organs was formed by adding tall pedal towers with symmetrically surrounding windows aside the medium-sized prospects
