In Greek mythology, Horme (/ˈhɔːrmiː/; Ancient Greek: Ὁρμή) is the Greek spirit personifying energetic activity, impulse or effort (to do a thing), eagerness, setting oneself in motion, and starting an action, and particularly onrush in battle. She had an altar at Athens, where mainly the divine servants and relations of Zeus (including Pheme and Aidos, as well as Athena) had altars.[1] Her opposite character is Aergia, a goddess of sloth and apathy. The word "horme" is also used to refer to the philosophical concept represented by the goddess.[2]
