Mikuláš of Kadaň (Czech: Mikuláš z Kadaně) (born 1350, Kadaň – died 1419, Prague) was an Imperial clockmaker.
With Jan Šindel, Mikuláš designed the oldest part of the Orloj (which also known as Prague Astronomical Clock).[1]
The clock was modified by Master Hanuš, who was mistakenly identified as the creator of the clock in a legend related by Alois Jirásek.
