Moon/Mercury combines the lunar emotions, bonding, and nurturance with the movement, thought, speech and communication associated with the Mercury archetype:
In astrology communication, speech and thought are associated with Mercury. The emotions, childhood, family and home are associated with the Moon. If you were born when the Moon and Mercury were in alignment the communication (Mercury) is often emotional (Moon) and the way to process emotions (Moon) involves communication (Mercury), i.e. having a chat with a close intimate.
This combination is a huge potential strength once it is understood.
If the birth data we have for Shakespeare is correct then he was born when the Moon and Mercury were aligned. Think of how the words he wrote (Mercury) have been able to emotional move (Moon) millions upon millions of people.
One of my favorite artists born with this combination is Mick Jones, musician and founding member of the band The Clash. Through his songs he creates an atmosphere of close intimate (Moon) communication (Mercury), whether he is singing about a childhood friendship https://www.youtube.com/watch?v=FuYzsrYSQx4, home life in the inner city https://www.youtube.com/watch?v=awCSxY0sd7E, child-like innocence in consumer society https://www.youtube.com/watch?v=qsrEAWcAvRg. He is even able to communicate (Mercury) the same sentimental (Moon) tone when singing about somebody getting murdered https://www.youtube.com/watch?v=FUNXA3srhYI. His messages (Mercury) in his songs really touch people emotionally (Moon); just look at the comment sections in the Youtube videos.
The Moon/Mercury combination in the chart of Henry Ford can be seen in his tendency to combine subjects associated with Mercury, such as thinking, learning, knowledge, and movement, with lunar associations, such as comfort, community, subjective emotions, and nurturance. The following are quotes from Henry Ford: “The only real security a man can have in this world is a reserve of knowledge, experience and ability.” “If everyone is moving forward together, then success takes care of itself.” “Whether you think you can or you think you can’t, you’re right.” “Failure is an opportunity to begin again more intelligently.” “Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young. The greatest thing in life is to keep your mind young.”
