Upper left and right image, reconstruction of the Indo-Germanic (Indo-European) language family by Schleicher (1853; 1861: 7). The left image dates from 1853, and the diagram was drawn in analogy to a plant. The image on the right dates from 1861 and resembles a tree diagram. The latter image especially needs to be interpreted from within both a historic and evolutionary view. Lower image, Čelakovský’s (1853: 3) tree diagram that represents the historic affinity of the Slavic languages
