Scrofa semilanuta

According to this legend (which partially draws from Livy's writings), the founder of Milan was a Gaul prince named Belloveso.

Other ancient sources (most notably the aforementioned Alciato, who in turns credits Ambrose for his account) report that the half-woolly sow is actually a sort of Chimera — half boar and half ram — and that the emblem came about when the Bituriges and the Aedui, having as their emblems a ram and a boar respectively, joined in the Po Valley.

The origin of the legend of scrofa semilanuta and the circumstances of its adoption as an emblem of Milan are a very controversial matter for scholars.

[1] A key element of this controversy is a bas relief affixed to the walls of the Palazzo della Ragione, former broletto (administrative building) of the medieval commune of Milan.

Another (more recent) representation of the "scrofa semilanuta" is found in the internal courtyard of Palazzo Marino (Milan's city hall).
