Oh, so he thought it was heretic to the Church

Yes. Justinian was promoting Christianity. The Greek philosophers, especially at the Athenian school were teaching what Justinian considered heretical to Christian teachings.

Thank you very much

You're very welcome.

Emperor Justinian, the Byzantine Emperor at the time, did not explicitly outlaw Greek Philosophy in 529 AD. However, he did take measures that indirectly impacted the study of philosophy in Byzantium.

In 529 AD, Justinian issued a decree called the "Closing of the Academy," targeting the Neoplatonic school in Athens. The Neoplatonic school was one of the last centers of Greek philosophy and was attracting prominent thinkers of the time. The closure of the school symbolized a shift in educational priorities and religious orthodoxy rather than a direct ban on philosophy or Greek thought.

Here's how you can find more information about this historical event:

1. Consult historical sources: Look for primary sources from that period. These may include writings and documents from Justinian's reign, such as his decrees, letters, or accounts of his courtiers and contemporaries. These sources provide insights into the motivations behind Justinian's actions.

2. Study Byzantine history: Familiarize yourself with the social, political, and religious context of the Byzantine Empire during Justinian's reign. Understand the relationship between the Emperor and religious institutions like the Church, as well as the prevailing religious beliefs and tensions of the time.

3. Research Neoplatonism: Investigate the significance of the Neoplatonic school in Athens and its influence on Byzantine intellectual circles. Neoplatonism was influenced by classical Greek philosophy and incorporated elements of mysticism and religious thought. Explore how Justinian's religious views may have clashed with Neoplatonic ideas.

4. Consult academic works: Look for scholarly books, articles, or research papers on Justinian's reign and his policies towards philosophy and Greek thought. Experts in Byzantine studies or ancient philosophy can provide detailed analyses and interpretations to deepen your understanding.

Remember, it's important to approach historical research with an open mind, acknowledging that historical events often have multifaceted causes that can be difficult to fully understand.
