This pair of maps of Eriwan [Yerevan] and Göktscahi [Sevan Lake], on one hand, and Lake Urmia, on the other, can be found in Eine Reise durch Vorderasien im Jahre 1904 written by Erich Zugmayer. The left-hand map shows Yerevan and Sevan Lake with lakes and hills marked in different colors. The map to the right gives a view of Lake Urmia with surrounding towns and roads. Two other maps appended to this book about the author’s journey from Vienna to Tbilisi through Russian Transcaucasia show the eastern part of Chiwa and Kojun Daghi.
