The blood eagle

Vikings as portrayed in a 19th-century source: fearsome warriors and sea raiders.

Things not to do when you travel in time. No.238: don’t kill a Viking, then let yourself get captured by his vengeful son. The result is unlikely to be pleasant; in fact, according to a number of histories, it would probably involve your own gory sacrifice to Odin in an unpleasant and agonising rite known as “the blood eagle.”

Turn aside now if you’re reading this while eating.

At its most elaborate, sketched by Sharon Turner in the History of the Anglo-Saxons (1799) or J.M. Lappenberg in his History of England Under the Anglo-Saxon Kings (1834), the ritual involved several distinct stages. First the intended victim would be restrained, face down; next, the shape of an eagle with outstretched wings would be cut into his back. After that, his ribs would be hacked from his spine with an ax, one by one, and the bones and skin on both sides pulled outward to create a pair of “wings” from the man’s back. The victim, it is said, would still be alive at this point to experience the agony of what Turner terms “saline stimulant”—having salt rubbed, quite literally, into his vast wound. After that, his exposed lungs would be pulled out of his body and spread over his “wings,” offering witnesses the sight of a final bird-like “fluttering” as he died.

Famous victims of the blood eagle are supposed to have included Ælla, king of Northumbria, Halfdán Long-legs, and Maelgualai, King of Munster. But, as this week’s Smithsonian essay points out, historians remain divided as to whether it was a real ritual–or a violent sort of historic libel. Weigh the evidence for yourself, then decide.

The Swedish Meteor: the blazing career and mysterious death of Charles XII

Sweden has had her share of memorable monarchs. In the 16th and 17th centuries, it seemed that every other ruler crowned in Stockholm was astonishing in one way or another. Gustav Vasa, Gustavus Adolphus, Queen Christina, Charles XI–between them, to the surprise of generations of students who have presumed that the conjunction of the words “Swedish” and “imperialism” in their textbooks is some sort of typographical error, they turned the country into the greatest power in northern Europe. “I had no inkling,” the writer Gary Dean Peterson admits in his study of this period, “that the boots of Swedish soldiers once trod the streets of Moscow, that Swedish generals had conquered Prague and stood at the gates of Vienna. Only vaguely did I understand that a Swedish king had defeated the Holy Roman Emperor and held court on the Rhine, that a Swede had mounted the throne of Poland, then held at bay the Russian and Turk.” But they did and he had.

The Swedish monarchs of this period were fortunate. They ruled at a time when England, France and Germany were torn apart by wars between Catholics and Protestants, as the great Polish-Lithuanian Commonwealth began its steep decline and before Muscovy had transformed itself into Russia and begun its drive to the west. Yet their empire endured into the 1720s, and even then it took two decades of constant war to destroy it—not to mention an overwhelming alliance of all of their enemies, led by the formidable Peter the Great.

The strange tale of the Warsaw basilisk

Few creatures have struck more terror into more hearts for longer than the basilisk: a crested snake, hatched from a cock’s egg, that was widely believed to wither landscapes with its breath and kill with a glare. The example to the right comes from a German bestiary, but the earliest description that we have was given by Pliny the Elder, who described the basilisk in his pioneering Natural History (79AD) – the 37 volumes of which he completed shortly before being suffocated by the sulphurous fumes of Vesuvius while investigating the eruption that consumed Pompeii. According to the Roman savant, it was a small animal, “not more than 12 fingers in length,” but astoundingly deadly nonetheless. “He does not impel his body, like other serpents, by a multiplied flexion,” Pliny wrote, “but advances loftily and upright” – a description that accords with the popular notion that the basilisk is the king of serpents – and “kills the shrubs, not only by contact, but by breathing on them, and splits rocks, such power of evil is there in him.” The basilisk was native to Libya, it was said, and the Romans believed that the Sahara had been fertile land until an infestation of basilisks turned it into a desert.

Pliny is not the only ancient author to mention the basilisk. The Roman poet Lucan, writing only a few years later, described another characteristic commonly ascribed to the monster – the idea that it was so venomous that if a man on horseback stabbed one with a spear, the poison would flow up through the weapon and kill not only the rider but the horse as well. The only creature that the basilisk feared was the weasel, which ate rue to render it impervious to its venom, and would chase and kill the serpent in its lair.

The basilisk was popular in medieval bestiaries, and it was in this period that a great deal of additional myth grew up around it. It became less a serpent than a mix of snake and rooster; it was almost literally hellish.
