Question

Which country has as its national coat of arms a shield bearing a vicuna, a cinchona tree and a cornucopia spilling mineral wealth in the shape of coins?

Answer 1

Armillary sphere
The sphere consists of a framework of brass rings, centred on Earth or (at one time in the West) the Sun, that represent lines of celestial longitude and latitude and other astronomically important features, such as the ecliptic. It is designed to demonstrate the principal circles of the heavens.
