Mercury, mythologically the messenger Hermes, represents our style
of communication, learning, thinking, and problem solving. By sign
and house, it also suggests how we process and interpret information,
how we are curious and open to learning, and how we frame our concepts
and "mind maps" for reality. It gives us the ability to
observe, to reason, to use intellect, to perceive, and to communicate.
It is probably placed in our charts in the region that needs the
most articulation. It suggests how we "tell our story".
Mercury, when we allow its energy to run unharnessed, can show
up as nervousness, inconsistency, scattered thought processes that
result in little accomplishment, too much idle chattering, poor
listening skills, and a lack of focus. A well-functioning Mercury
engenders the ability to articulate and communicate clearly, to
process information capably, to gather data from a variety of sources,
and to formulate paradigms of thought. Its placement by sign and
house indicates how an individual best accomplishes that.
