Discovered in the necropolis of Saqqara, Egypt, in 1898, a small wooden object shaped like a bird has sparked decades of debate. Known today as the Saqqara Bird, some researchers have claimed it represents an early model of a glider, evidence that ancient Egyptians may have experimented with flight long before modern aviation.

But does the evidence support that claim?

In this episode of History Undisclosed, we examine the artifact’s discovery, its construction and proportions, the aerodynamic experiments performed on replicas, and the competing interpretations proposed by archaeologists and engineers. We explore whether the object was truly designed with flight in mind, or whether modern observers are projecting technological assumptions onto an ancient ceremonial or symbolic item.

Discovered near modern-day Baghdad in the 1930s, a small clay vessel containing a copper cylinder and an iron rod sparked one of the most enduring debates in alternative archaeology. Could this object, now known as the Baghdad Battery, represent evidence of ancient electrical knowledge?

In this episode of History Undisclosed, we take a careful, evidence-based look at the artifact’s discovery, construction, and historical context. We examine the experiments that claim it could generate electricity, the serious objections raised by archaeologists and engineers, and the alternative explanations that often receive far less attention.

For nearly two thousand years, a weapon known as the Spear of Destiny, also called the Holy Lance, has been linked to conquest, divine authority, and political power. Said to be the spear that pierced the side of Jesus Christ during the crucifixion, multiple versions of the relic exist, each claiming authenticity—and each surrounded by legend.

In this episode of History Undisclosed, we trace the real historical trail of the Holy Lance: from late Roman accounts to medieval coronations, from imperial propaganda to 20th-century obsession. We examine how the spear became associated with rulers, why possession of it was believed to confer divine right, and how myth steadily overtook evidence.

Rather than chasing supernatural claims, this documentary focuses on sources, provenance, and political context. We explore how relics gain power not through miracles, but through belief, symbolism, and authority.

If you enjoy historical mysteries explored with skepticism and evidence, this episode is for you.
