Historic Centaurus & Lupus – The vines and the spear

The constellation Centaurus, closely associated with Lupus and Crux, changed a lot as history progressed. The original Centaurus was probably depicted as a Centaur, holding a hunted animal Therion (usually a goat) and a flask in one hand, and holding a spear with a rabbit hanging from it in the other.

Muslim period prefers the depiction of Lupus as a lion-like animal, called al Sabu’ (“the wild beast”), not to be confused with al Asad (“the lion”). The Muslim was also the first to introduced the idea that the sacrificed animal is held at its hind paws.

The spear is replaced with a vine here, following the traditional Arabic rendition of some of the stars as Al Kadb al Karm, “the Vine Branch” and sometimes as Al Shamarih, “the broken-off Palm Branches loaded with dates” which Kazwini described as held out in the Centaur's hands. Some thought that the vine branch represents’ the Greek thyrsus, Dionysus’ vine staff. Source: Kitab Suwar al Kawakib

Being an almost southern constellation, many modern maps of Centaurus shows it as part of the group around Hydra, so it is actually kinda difficult to find a decend image of Centaurus.

Strasbourg Astronomical Clock

Inside Strasbourg Cathedral, world’ tallest building in 200 years, lies an 18 meter astronomical clock, also one of the largest in the world. The “astronomical clock” could indicates leap years, equinoxes, days, time, month, year, zodiac signs, moon phase, planetary positions, and more astronomical data, so it is already much more a complex calculating machine than a clock.

Historic Boötes and Canes Venatici

I came into this inspiring blog focusing on medieval literature and arts. One of his entry talks about the historic representation of Bootes and how Canes Venatici came to be. It’s a short entry but very informative, but he only has Bootes. So I was thinking why not posting the entire constellation from its earliest representation to the most current representation in my blog. So in regards with the List of Figures entry of Bootes, let’s rewrite the entry here, and next, the rest of the constellation.

In Limoges Aratea (early 11th century), Bootes was depicted holding the crooked staff in a manner as if he is driving something (Ursa Major) to walk. Source: Limoges Aratea

 

auv0078

9th century Assyrian scholar Hunayn ibn Ishaq converted the crooked staff into “spearshaft with a hook” because he didn’t know the Greek word Κολλοροβος, and so he translated it into the nearest Arabic word, arriving at العصى ذات الكلاب , al ‘Ashadzat al Kullab, “spearshaft with a hook”. source: Kitab Suwar al Kawakib

 

In the first half of the 12th century, several decades after Alfonso VI conquered Toledo from the Moors, Italian scholar Gerard of Cremona found a copy of Almagest in one of the city’s former Islamic library and translated into Latin, bringing the text back to the Western Civilization. He mixed up the words kullab, “hook” into kilab, “dogs” and so the hastile haben canes, “spearshaft with dogs” was born. This dogs reappears in various star charts of the next era.

Bayer in his Uranometria (1624) has Bootes with a spear shaft and a sickle. The stack of wheat(now Coma Berenices) provides a nice foreground.

Bootes    Greyhounds(?) at the Roman Villa

Hevelius published Uranographia (1687), proposing Canes Venatici as the official constellation - dogs of Bootes. He decided the dogs to be greyhounds in Greeks: Asterion (“little star”) and Chara (“joy”). He also introduced Mons Maenalus, a mountain in Greece that Boötes is stepping upon. This time Bootes appears in his middle-age appearance, different with the younger original. His depiction of Bootes probably determines the modern shape of the figure. Source: Wikipedia

There is no official modern depiction of Bootes but in conclusion, most modern depiction of Bootes tries to incorporate everything that is there in the past. He carries many appliances of a herdsman: the crooked staff is now represented by the sickle, while his other arm, supposedly straight in line, is represented with a longer lance or staff. The dogs are depicted pursuing Ursa Major, but not hunting it.
