Did Mercury cause Nervous Breakdown of Isaac Newton

Was it Mercury planet or Mercury element that caused Isaac Newton’s nervous breakdown? This article analyses his available Birth Chart in order to find an answer.


Isaac Newton was born on 25th December 1642 in England. He was a mathematician, scientist and author, best known for his work Philosophiae Naturalis and Principia Mathematica on the theory of gravitation.

He was Born Weak and Premature

His natal Moon falls in the constellation of Mars and it is debilitated in the Navamsha (D/9) chart. His ascendant falls in the constellation Shatabisha of Rahu and Rahu is placed in the 8th house. Because of these conditions he was born as a very tiny and weak baby about three months premature.


By Nature he was Deeply Introverted

In his horoscope Rahu (Moon’s North Node) falls in the constellation Hasta of Moon therefore mainly Rahu’s main period from 1643 till 1661 was responsible for his deeply introverted nature. Because of this he always felt insecure and remained secluded in spite of being recognised as a foremost thinker.


Venus gave him Generosity and Kindness

In his birth chart the Yogakarak 4th and 9th lord Venus is well posited in the ascendant. Also there is sign exchange between the ascendant and the 2nd house. These conditions made him a generous and kind person especially during his later years during the sub-period of Venus in the main period of Mercury.

Planet Mercury caused his Nervous Breakdown

All his psychological problems concluded with a nervous breakdown during the sub-period of Mercury in the main period of Saturn. In his birth chart Mercury which is enemy of Mars occupies the sign Scorpio and also it is aspected by Mars.

He recovered from this during the sub-period of Venus.

Mercury Planet and not Mercury Element caused his Breakdown

It is believed by some that as a result of his alchemy experiments he was poisoned by fumes of the element Mercury also known as quicksilver. So his madness or nervous breakdown is attributed to consumption of Mercury element.

But the above astrological analysis of his birth chart reveals the planet Mercury behind his nervous breakdown. Well who knows it could be both viz. Mercury as planet and Mercury as element.
