The adjective “aquiline” comes from the  Latin “aquila,” meaning “eagle”. This Latin root is the name of a constellation located on the celestial equator. Aquila represents the eagle associated with the god Jupiter (or Zeus in Greek mythology), and the constellation was first recorded by Greek astronomer Ptolemy in the second century. The adjective “aquiline” is not commonly used to refer to the majestic birds themselves, but instead to things that are like an eagle. The most common usage of “aquiline” is to describe a specific shape of a person’s nose: prominent and curved, like that of an eagle’s beak.
