The King of Pentacles is called the Prince of the Chariot of Earth and he represents mastery of the physical realm - health, finances, property and skills. He is linked to the earthy astrological signs of Taurus, Virgo and Capricorn.
He is hardworking, patient, successful and determined. A generous soul, he is nevertheless careful and not foolish with his money or other resources, but he understands that generosity and focus on building wealth and assets that last are both linked.
He looks after his possessions and is careful with security. He is brilliant at nurturing physical assets and is often linked to the land, in building or in finance in his profession. He can appear fussy when considering the details of any important decision and usually takes much longer than others to finalise matters.
As a partner or potential partner he is steady, stable and often somewhat stubborn. He does not change his mind easily and not without good cause and plenty of evidence to support a change.
He is sensual and earthy - he likes the sensation of touch and will hold on to a relationship doggedly and faithfully once he has committed himself. He has a strong and passionate heart that is devoted to family and the foundations of family life. He can be jealous and possessive if there is any ambivalence or uncertainty in his relationship with his chosen partner. He is a good provider.
On an abstract level, the King of Pentacles represents institutions, traditions and professional organisations dealing with property and money.
When he turns up in a reading for you, he is telling you it is time to take care of finances and your long term security and his presence brings opportunities for you to do this now and to make it a priority.
His appearance also is calling on you to pay attention to and master your health and fitness, as he knows the body is the foundation of all of life's riches.
