Signs from the 9th Century, Inspired by Greek Letters, Found on the Vistula

In 1986 during the archaeological excavations by the Institute of Archaeology of the University of Warsaw directed by professor Jerzy Gąssowski at the site of Podebłocie, three small fragmentary objects of clay were found. On these so-called ‘tablets’ there are signs which are similar to the letters of Greek alphabet (ill. 2,3,4). Finds of that kind, unexpected in that area, excited a lot of interest of Polish mediaevalists.
