The most important sources and links I have consulted during my studies of astronomical clocks.

Firts of all, my special thanks to Mr. Frans Arts, artist and astronomical clock builder from Gemert (The Netherlands), who has shown me how to calculate and design astronomical clocks. Partially due to his thorough explanation I have managed to successfully live up to the challenge of how to make an astronomical clock. Feel free to visit the website of Frans Arts ( where not only you can see astronomical clocks but also special works of art.
