How did the practice of haruspicy decline over time?

Haruspicy, the practice of divination through inspecting animal entrails, declined due to several factors. The rise of rational thought and scientific inquiry during the Enlightenment diminished reliance on superstition. Additionally, the spread of Christianity, which often condemned pagan practices, led to a loss of cultural support for haruspicy. By the late medieval period, it had largely fallen out of favor.
