Neptune The Mystical Child ~ An Ice Giant
Neptune, named for the god of the sea, is the eighth and farthest planet from our Sun. You cannot see Neptune without a telescope. She was discovered through the use of math. Neptune is a beautiful pale ocean blue color. Neptune is classified as an Ice Giant, in contrast to Jupiter and Saturn, which are Gas Giants. Uranus and Neptune do not possess a deep metallic hydrogen mantle.
All Outer planets are generational planets; they take significant amounts of time to move through the signs of the Zodiac. The outer planets influence the collective unconscious, expressing each generation’s unique message or zeitgeist through music, art, fads, and current trends.
It takes Neptune 165 years to orbit the Sun. The last time that Neptune was in Aries was from 1861 to 1874.
Neptune seeks to commune with The All That Is. She tries to show us the way to our higher selves. Neptune offers spiritual guidance and psychic awareness through dreams and intuition. When we mindfully connect with Neptune, she provides a pathway to opening up to our artistic talent, accepting transcendent spiritual experiences, and embracing agape.
Her transits can become tricky when Neptune’s energies are misused or distorted. Neptune’s ethereal quality can indulge in unrealistic fantasies, avoidant and addictive behaviors, and cause confusion. Neptune can be deceptive, leading to poor decision-making and self-defeating behavior. Neptune is most at home in Pisces, feels restricted in Virgo, inspires in Sagittarius, and is prone to skepticism in Gemini.
Neptune will be transiting in Aries for the next 14 years. Aries is a fire sign, masculine, cardinal, and ruled by the warrior god Mars, making this sign action-oriented, competitive, and impatient. The Aries journey revolves around self-awareness, discovering who you are, and becoming a self-actualized confident individual.
Understanding Neptune in Aries through History
When we want to know how a planet’s new ingress will manifest, astrologers look at the historical periods when the planet was transiting in the sign that the planet is about to enter.
Looking back in history at the times when Neptune has been transiting in Aries, we find some interesting themes.
Going back to 1042 -1057, the Catholic papacy was in complete chaos. Papal legitimacy was an issue; at one point, there were three rival popes. To solve the crisis, the German King, Henry 3rd, deposed all three competing popes and installed his own choice, Pope Clement 2, ushering in Gregorian Reform.
1206 – 1220 Several failed Crusades, including a Crusade of mostly children. Genghis Khan gained power and the Silk Road expanded.
The Magna Carta was written, declaring that the sovereign was subject to the rule of law and the document served as the foundation of English Common Law.
Jumping to 1533- 1548, we find Henry the 8th initiating the English Reformation, declaring himself head of the Church of England, and transforming England from a Catholic country to a Protestant. In Denmark and Norway, the Lutheran Reformation takes place, and the Calvinist Reformation in Scotland. The Spanish Inquisition burns its first Protestant victim. The formation of catholic religious orders and multiple missions to convert people to Christianity by both Protestants and Catholics.
1697 – 1712 These years are less about religion or reforms and more about royal power and wars of expansion.
1861- 1874, the last time Neptune traveled in Aries, The United States was busy fighting a Civil War, and slavery in America finally ended. The First Vatican Council proclaims papal infallibility on matters of faith and morals. The Suez Canal opens. In Japan, the era of the Shogunate ends. Marxism was born, opioids were introduced to the world market, oil refining began, and telegraphs connected the east and west coasts of the US.
Themes of Neptune in Aries
Looking at the timeline of Neptune in Aries, some interesting themes emerged. The timeline is filled with religious scandals and ideological schisms that led to reforms. The catholic church has a significant amount of events happening while Neptune transits in Aries. New ideologies about religion and human rights take hold, fermenting uprisings, civil wars, and revolutions. Bold actions by individuals willing to take risks to spread religious doctrines, challenge the economic status quo, and break long-held institutional power.
What we might see 2025 to 2039
Neptune in Aries will favor those who are bold, enterprising, and willing to break barriers and go on new spiritual adventures. I would expect that religions and spirituality, in general, will experience new expressions, possibly new spiritual movements, or religious orders. Like previous transits, there will be schisms, scandals, and reforms.
There will be a focus on world leadership, with ruthless dictators and charismatic hero figures emerging. Aries seeks to take action and can be impulsive, while Neptune prefers to go with the flow; this combination may lead to unrealistic, misguided expectations and goals. Neptune rules artistic expression while transiting in Aries’s art, music, and fashion will be bold, edgy, challenging, and embrace individualism.
