UPPSALA, SWEDEN — After years of painstaking research and untold grant money, archaeologists have finally solved the millennia-old mystery of why medieval soldiers often exhibited square holes in their skulls: they were hit with spiked clubs. A groundbreaking new analysis of skeletal remains from a 14th-century battle near Gotland, Sweden, definitively concludes that blunt force trauma from multi-pronged bludgeons frequently resulted in fatal cranial injury.

"For generations, historians have grappled with the perplexing phenomenon of these perfectly squared apertures in the crania of fallen warriors," stated Dr. Astrid Nielsen, lead researcher from the newly formed Institute for the Self-Evident in Ancient Warfare. "Was it ritualistic? A bizarre form of medieval dentistry? We now have irrefutable evidence that, no, it was just dudes getting brained with weapons explicitly designed to brain them. We even found trace amounts of 'brain' in some of the square holes, further cementing our hypothesis."

The study, published in the prestigious *Journal of Obvious Historical Conclusions*, meticulously details how the 'morning star' — a spiked ball attached to a stick — creates an impact pattern remarkably consistent with, well, a spiked ball hitting a human head at high velocity. Researchers employed cutting-edge forensic reconstruction techniques, including dropping various historically accurate spiked implements onto replica skulls made from modern cadaver bone, which Dr. Nielsen described as "surprisingly conclusive, if a bit messy, and certainly not for the faint of heart or stomach."

Further findings suggest that the act of "swinging said spiked club with considerable force," often while wearing heavy armor and expressing hostile intent, played a critical role in the observed skull deformation. One anonymous source close to the project, speaking on condition of anonymity due to the sensitive nature of stating facts that literally anyone with a pulse could deduce, noted, "It seems when one individual, often described in historical texts as 'the enemy,' applies a heavy, pointy object to another individual's head in a combat scenario, the outcome is rarely a vigorous high-five or a polite exchange of philosophical musings."

The research team plans to extend its inquiry into other historical conundrums that have baffled scholars for centuries. These include determining "why arrows are pointy," "whether swords are designed for hugging," and investigating preliminary data suggesting that being set on fire during a siege is, in fact, "suboptimal" for long-term health. The institute is also seeking funding for a meta-analysis on whether medieval combatants preferred to avoid death where possible.

"The next phase," Dr. Nielsen added, pausing to wipe what appeared to be synthetic gore from her spectacles, "is to determine if yelling 'ow' was the predominant medieval battle cry immediately after sustaining such an injury, or if a more guttural expression of displeasure was common."
