The Astrolabe by Wilfred de Graaf
โOne of the most widely used astronomical instruments over time is the astrolabe. Astrolabes were mainly used for two purposes: for astronomical observations and calculations, and for astrology. In this treatise we focus on the astronomical purposes of the astrolabe.
The astrolabe is a flat and portable instrument mostly made of brass on which the positions of the sun and some of the major stars are projected relatively to the observers horizon. Its mathematical principles date back to Greek antiquity. The principle of stereographic projection was known to the Greek astronomer Hipparchus of Nicaea (150 B.C.). Although it remains uncertain, it seems probable that Ptolemy used an instrument like the astrolabe. Certain is that he wrote a treatise on stereographic projection. Unfortunately no Greek astrolabes have survived.โ

Apparently it was a habit among some British Celts to make combs out of bits of human skulls or bones. So far, three such combs have been found, all in Cambridgeshire, England, and dating to the time just before the Roman invasion of the island. The fact that theyโve only ever been found in one region could be indicative of a unique habit among the locals of the area.

Limestone statue depicting a wolf, from Noves, in Bouches-du-Rhรดne, France; 2nd or 3rd century B.C. ๐ซ๐ท The statue, known as โLa Tarasque de Novesโ was found under a 19th century cemetery and is now on display in the Musรฉe Lapidaire, in Avignon, France.
After its initial discovery, locals had imagined it as a depiction of a mythical reptilian monster known as โLa Tarasqueโ; hence the name given to it. But more careful recent observations have led to the conclusion that the statue was meant to represent a wolf: The long snout, thick hair along the back, non-retractable claws, and a broad, tapering tail (tucked under the right leg), are all traits characteristic of a wolf.
The Noves wolf sits upright like a king, grimly enjoying a meal of human flesh and triumphantly displaying the severed heads of two victims, in classic Celtic warrior fashion. The long beards on the victimsโ faces appear to imply that they were intended as members of nobility, perhaps even as kings. The ancient stonemasons carved a penis and testicles onto the wolf, probably to leave no room for doubt as to its intended gender (there are only two), as well as to emphasize the attribute of virility.
