Today I went to the Brooklyn Museum. There I found nothing particularly special, except for the African art collection. But I just wanted to spend time indoors, away from the cold - worse than cold: "frigid", the NY Times says -, and the visit served that purpose.
This is a Dan mask. Individuals wearing masks like this one "were believed to be incarnate spiritual beings capable of rendering unbiased judgments". It's made of wood, organic material (?), monkey skin (!), and iron nails. It was found in Liberia and dates from the 19th century.
