It began with the parade of the 26 Guilds of Zürich. I simply give you the pictures because my knowledge of Swiss culture generally, and Zürich culture specifically, is too limited to explain what is happening.
The parade ended in Sechseläutenplatz and all of the spectators gathered to witness the Death of the Böögg.
We slowly worked our way through the massive crowd, craning our necks for a glimpse of the Böögg. We heard the church bells ring 6 o'clock and a shout rose up from the crowd. As we could see nothing but the backs of heads, we could only assume that the bonfire had been lit.
Soon a thick smoke filled the sky.
And still we worked through the crowd until, at last, we had our first glimpse of the giant snowman. Flames were already creeping up around him.
Soon he was completely engulfed and a series of rapid explosions began.
Until finally one enormous explosion ripped through the air...
The head came off and the Böögg was no more...
By my watch, the head came off at approximately 12 past the hour. This was confirmed by SwissInfo.org, which stated the time was 12 minutes and 9 seconds.
Apparently we are in for a moderately hot summer.
That is if you believe that an enormous snowman can predict the weather based upon how long he takes to die.
