WThe 52-hertz whale is an individual whale of unidentified species which calls at the unusual frequency of 52 Hz. This pitch is a higher frequency than that of the other whale species with migration patterns most closely resembling the 52-hertz whale's – the blue whale (10–39 Hz) or fin whale (20 Hz). It has been detected regularly in many locations since the late 1980s and appears to be the only individual emitting a whale call at this frequency. It has been described as the "world's loneliest whale".

WThe legend of the green children of Woolpit concerns two children of unusual skin colour who reportedly appeared in the village of Woolpit in Suffolk, England, some time in the 12th century, perhaps during the reign of King Stephen. The children, brother and sister, were of generally normal appearance except for the green colour of their skin. They spoke in an unknown language, and would only eat raw broad beans. Eventually they learned to eat other food and lost their green colour, but the boy was sickly and died soon after he and his sister were baptised. The girl adjusted to her new life, but she was considered to be "rather loose and wanton in her conduct". After she learned to speak English, the girl explained that she and her brother had come from Saint Martin's Land, a subterranean world inhabited by green people.

WThe location of the tomb of Alexander the Great is an enduring mystery. Shortly after Alexander's death in Babylon, the possession of his body became a subject of negotiations between Perdiccas, Ptolemy I Soter, and Seleucus I Nicator. According to Nicholas J. Saunders, while Babylon was the "obvious site" for Alexander's resting place, some favored interring the ruler in the Argead burial at Aegae, modern Vergina. Aegae was one of the two originally proposed resting places, according to Saunders, the other being Siwa Oasis and in 321 BC Perdiccas presumably chose Aegae. The body, however, was hijacked en route by Ptolemy I Soter. According to Pausanias and the contemporary Parian Chronicle records for the years 321–320 BC, Ptolemy initially buried Alexander in Memphis. In the late 4th or early 3rd century BC, during the early Ptolemaic dynasty, Alexander's body was transferred from Memphis to Alexandria, where it was reburied.
