Now a days the Museums don’t usually show Statues like they were back in the Days. In that they were painted to be more life like. Also the artist used with colored shells, paint and even jewels at times. I guess that it just freaks out a lot of folks today.
But now you know! Also if you can get close enough to the statue. You can sometimes see traces of the old paint that has survived time and the elements. Grumpy
