If you are familiar with Maserati, perhaps you have one, then you will know that the emblem of the car is a trident.
Maserati began on December 1, 1914 in Bologna. One of the Maserati brothers, Mario, was an artist. He is said to have devised the trident emblem. It is believed that the company wanted something that represented Bologna, something recognisable.
The crystal encrusted Maserati was on display in Bologna when I was there. I’m not quite sure why this was done, but it looks quite impressive.
The Neptune in Bologna is the most impressive and powerful one I have seen. There were some very puny Neptunes in Spain and France. The Italians obviously liked their gods tough.
