of PhD Theses The Thesis is centred around the influence the Lazansky of Bukova aristocratic family had on the artistic environment in the Czech lands from the 16th to 20th century. On the background of their cultural-historical monograph, the author introduces the individual family member's construction and patronage activities, the development of their art collections and the wider context. Using the interdisciplinary research, the author con- fronts the results of his own work with the conclusions of previous researchers. He chal- lenges some of the earlier hypotheses for the Early Modern Age and draws from the untapped sources a wealth of information about the Lazansky family cultural activities in the modern history. He compares the resulting summary with the realizations of other aristocratic families in the Czech lands and in Central Europe. The author's efforts result is the first comprehensive view of the Lazansky of Bukova family in the wider context of cultural history, and in the rehabilitation of their role in artistic patronage.
