Is it old or new?
That piece is actually from the 20th century, so not too old.
It looks like these two works could have been made by the same people but they come from very distant places (Papua New Guinea on the LHS, Mali on the RHS). Are they connected? Is there a common history between these two places?
While they have visual similarities - narrow, vertically thrusting, and both made of wood indigenous to their respective topographies, the two groups do not have a common history beyond the Western history of "primitive art," which used to lump Africa and the Pacific together.
The object on the left from the Abelum culture in Papua New Guinea represents ngwalndu, benevolent spirits of individual clans who are considered responsible for clan prosperity. The figure on the right is from the Tellem or Dogon culture; it is a human form with its hands raised, which is said to refer to prayers for rain which would be crucial to the dry area of Mali that this object comes from. A figure with raised arms is one of the most common types of Dogon sculpture.
What is this?
This is a ceremonial house figure and it has so many different animals and figures depicted on it. Organic materials help imbue this object with a special presence. After being carved in the woods, the figure would be coated in mud and painted.
