What is this tune that plays in the first 15 seconds

Greetings Folks!

I would love to know from which composition the first 20 seconds is nicked from. The video link is given below. The tune appears to be Baroque, possibly something a Handel or Vivaldi might have composed. Hopefully, much more knowledgeable folk here would help me identify it:
