Many publications said that the symbol was the Isis as an homage to Alejandro's wife Isabella. It never made much sense to me, but that was the thinking for many years. Jan P. Norbuy wrote in "De Tomaso Pantera" (Osprey AutoHistory) that "De Tomaso designed his Egyptian derived symbol very early on. It's an "I", not a "T", for Isabel (his wife) not Tomaso, for the goddess Isis".
A few years ago it came out that the symbol was indeed the DeTomaso family brand that was branded to the cattle on the family estate in Argentina.
