In summary: the "Grisly Record of the Assyrians" is considered trustworthy because The Assyrian's own writings and art explicitly describe and depict scenes of torture and death, and Biblical accounts confirm their accuracy. They are not trustworthy. The Assyrians are likely just a myth. None of the above.

The Assyrians were a real civilization known for their significant contributions to art and culture, alongside their notorious military prowess. Their relief sculptures and written records, often depicting brutal warfare and their conquests, serve as historical evidence of their existence and practices. These artifacts are instrumental in understanding their society, which thrived from around 2500 BCE to 609 BCE in the region of modern-day Iraq. In terms of real-world application, the study of Assyrian records can provide insights into the nature of power, governance, and the impact of militaristic societies. By evaluating their historical accounts, modern historians can grasp the complex interplay between violence, culture, and authority, offering valuable lessons on the consequences of brutality and the quest for dominance in human history.
