An aquiline nose (also called a Roman nose or hook nose) is a human nose with a prominent bridge, giving it the appearance of being curved or slightly bent. The word aquiline comes from the Latin word aquilinus ("eagle-like"), an allusion to the curved beak of an eagle. While some have ascribed the aquiline nose to specific ethnic, racial, or geographic groups, and in some cases associated it with other supposed non-physical characteristics (i.e. intelligence, status, personality, etc., see below), no scientific studies or evidence support any such linkage. As with many phenotypical expressions (i.e. 'widow's peak', eye color, earwax type) it is found in many geographically diverse populations.
