Do you know this Painter?

 I bought a dish that I'm looking for some help with.  It is what looks like maybe a candy dish.  It has the signature on the bottom de Pisis, the back says Made Italy and it looks like it has a written number 766 although that could be something else.  I did find out that the painter de Pisis was from Italy but most of what I find on him is in Italian so I can't understand it.  Any help would be appreciated.
