    Markus RitterARTICLEIran and the Caucasus2009Cited by: 2

    The mosques in the citadel of Yerevan are lost today and almost unknown. Here, the most significant of them is reconstructed from visual and literary sources, documented by unpublished photographs, and related to the early Qajar period under the last Iranian governor Husayn Khān, prior to the Russian conquest of Yerevan in 1827. The second mosque in the citadel is attributed to the Ottoman period; the third one remains uncertain. While the type o…

    Markus Ritter, Susette Biber-Klemm et al.ARTICLEGAIA - Ecological Perspectives…1995

    The representations and values guiding people's perception of nature and possibly motivating action to preserve biological diversity are subject to historical change under specific social conditions. A historical case study of the process that led to the enactment of bird protection measures in Central Europe reveals that substantial value shifts occurred in the period of approximately 1850–1930, which can be observed within various discourses. W…
