Tudi stari Slovani so poznali gnomone

The belief that only written records of ancient Greek science are relevant to our knowledge of past science and that there is nothing outside of that knowledge that is not contained in written sources is misleading. The ancient Slavs were able to develop their knowledge of mathematics and astronomy independently of ancient Greek science. Neglecting the knowledge of the ancient Slavs in comparing it with that of the ancient Greeks is misguided and cannot lead to useful findings.
