Automatons like this musical clock in the form of a ship were used as festive table decorations intended to amuse and entertain the diners. The effect was increased when they were designed to mechanically imitate real-life action and could produce a melody as well. Gradually, the traditional centerpieces lost their original function and developed into mechanically moving toys and gadgets, and finally into automatons proper. A mechanism and a musical clockwork allowed this ship automaton to roll across the table, while the tiny musicians on it could be heard and seen to play their instruments. The date 1585 in the inscription and the imperial double eagle on the flags and banners suggest that the ship was intended for Rudolf II. Hans Schlottheim, who built several of these mechanical ships, was staying in Prague in 1587.
