Katarchic astrology

Katarchic astrology is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Katarchic astrology rather than just read about it. In short: Katarchic astrology is the implementation of a type of horoscopic astrology in order to determine when would be most beneficial and rewarding moment in time to take a venture or undertaking, and is also known as electional astrology. Electional astrology is typically used to interpret the level of success of a moment that has already taken place.

Key takeaways

  • Katarchic astrology belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Katarchic astrology to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Katarchic astrology from memory before moving on to harder problems.

Reference excerpt

Katarchic astrology is the implementation of a type of horoscopic astrology in order to determine when would be most beneficial and rewarding moment in time to take a venture or undertaking, and is also known as electional astrology. Electional astrology is typically used to interpret the level of success of a moment that has already taken place. In modern time, electional astrology is more commonly known as inceptional astrology. Hellenistic and Byzantine traditions used the term katarchē in order to refer to electional astrology and inceptional astrology, which is also part of Katarchic astrology. Katarkhé was used to discover and confirm events of the past. These events include following the history and path taken by a certain illness, or tracking missing items and people such as criminals or those escaping slavery. Originally when Katarchic astrology was practiced, it typically was used to determine the best timing to conduct events such as weddings, and also to answer specific questions. It guided individuals on whether or not to continue or proceed in a course of action and worked to help guarantee the ideal result. In more recent times, Katarchic astrology is used to predict the future of individuals and influence the outcome of their future.

Comparison to genethlialogy In comparison to genethlialogy, Katarchic astrology is seen to represent less of the idea that the events of life are predetermined. Where genethlialogy may see events as inevitable, Katarchic astrology thought it was possible to avoid the future the planets predicted for individuals. Some believe that those studying Katarchic Astrology were critical to the Roman Empire and had impact on the social and political aspects of this empire. Katarchic astrology alongside genethlialogy evolved into the better known interrogational astrology. This was also known as horary astrology at the time, and was the practice of finding an answer to a specific question in time through the use of a horoscopic chart.

Notable people in Katarchic astrology Dorotheus of Sidon is one of the more significant of all authors on the topic of Katarchic astrology. His work dates back to the first century CE. His writing was translated into Arabic ca. 800 CE. Dorotheus wrote a series of five books, each one relating to topics of Hellenistic astrology. Book 5 of Dorotheus "covers all forms of Katarchic astrology, including elections and interrogations". This book focuses on different experiences humans may have had, including but not limited to finding objects or people that may have been lost, or building on life's journey. Dorotheus's writing became known among other writers in the Byzantine period. Augustine is another notable historian with opinions on Katarchic astrology. He argued against topics of astrology and divination during his life time. He was first exposed to astrology as a Manichean before he converted to Christianity. His main argument against Katarchic astrology was the way it opposed the points made by natal astrology. He claims that if a person's future is laid out for them by their natal charts, how can choosing the timing of an event have an impact. He further explains that those astrologers who made correct predictions were truly "inspiration of evil diamons rather than the study of astrological techniques".

Worked examples

Example 1 — a first encounter with Katarchic astrology

Start with the simplest possible case. Write down what Katarchic astrology claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Katarchic astrology before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Katarchic astrology ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Katarchic astrology

In research
Katarchic astrology appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Katarchic astrology in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Katarchic astrology is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astrology by type, Astrology stubs, Hellenistic astrology, so understanding it makes those chapters shorter.
In everyday life
Look for Katarchic astrology outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
