Who discovered Jupiter's cloud belts?

Can anyone tell me who first discovered Jupiter's cloud belts? Galileo didn't see them; I'm thinking that Cassini or Huygens might be contenders. Great Red Spot is credited to Hooke (1664) in some sources so I assume the belts were seen prior to that.  If anyone knows (and can give me a reference) I'd be interested to know.

Edit: I think the answer is Evangelista Torricelli in 1630.

This paper is quite interesting too, on the question whether Hooke or Cassini discovered the GRS:

Further edit:

One source says the main belts were independently discovered by Torricelli, Fontana and Zucchi. Just thought I'd share that :).

Now I think my 15 minutes on this question are up.

I would opt for the shared reporting and "discovery".

For  two reasons  them being time to report any discovery back then was not a case of email and an automatic timestamp.. More like observe, double check, write up, then send to a body that may or may not think what you had written was satisfactory. Look up the history of Longitude.

The other one being I guess a reluctance to announce. I have seen a great red spot on Jupiter, could be met with I saw that over a month ago I claim the discovery not you. Unfortunately I think occured more then once, and to an extent still does (or did) even recently.

I have had a look,  first recorded in a book  by G. B. Riccioli...It say's The storminess of that atmosphere was observed by Leander Bandtius, Abbot of Dunisburgh on November 2nd 1632. Hope this helps  :smiley:

Reading that made me think the observations they were making back in the 16 hundreds were pretty amazing.  Telescopes don't seem to have got better, just more common.

The only advantage they would have had over us, would be wonderful Dark skies where ever they lived.
