II-Description of the astronomical clock

III-Automata and chiming mechanisms


This part of the clock is largely responsible of its popular reputation. Today, the 19 automata only operate at noon, at 2:00pm, 3:00pm and 4:00 pm in order not to disturb the religious services.

Here is the sequence of events : the angel holding a sand-glass salutes and tilts the sand-glass upside down, the rooster crows 3 times while craning its neck, opening its beak and beating the wings; the angel, conducting the orchestra, moves his head, lifts his stick and with his foot beats the time.

At this moment the angels holding small bells activate them and the bells play the hymn of Saint-John the Baptist : « Ut queant laxis ». At the same time the Swiss Guard starts his round, the scene of Annunciation comes to life. Mary is praying, the door opens and angel Gabriel appears, the Virgin slightly moves her head to listen to the Word of God ; the ceiling half-opens, the Holy spirit as a dove comes down to the Virgin.

Simultaneously, God the Father blesses his people three times. The angel and the dove retire, the door and the ceiling close, blessed by God the Virgin keeps praying. The Swiss Guard concludes his round and the big bell strikes the hour.
