The Hare may allude to the constellation Lepus at the feet of Orion. The "Eos(tre) Bunny", if you like. Not having seen this "21", perhaps it is really Pookah. With respect to the luni-solar calendar, Orion is poised roughly 180 degrees from Ophiucus (Serpentarius) - the "13th" House of the Zodiac - where the healer grasps hold of the Serpent. I've gotten the impression that the symbolism is related to the astrological glyphs for Scorpio & Virgo - between whom Ophiucus was poised before Scorpio's pincers were shortened to make way for Libra. The trick is seeing in seeing a Spiral from it's side, silhouetted upon a plane.
Among the luni-solar calendars of antiquity, calibrating the cycles of Sun & Moon was, in a sense, like joining two serpents coiling about the Earth. The formula usually had something to do with the golden mean, much like the 'solution' to the Tarot - but only if you can 'see' how the origins of alphabets & calendars are intertwined. Though, if you can multiply 0.618 with 365, you might appreciate how the Menses Intercalaris, as needed, tended to begin on 2.25

Emperors are often presented in context of Eagles:

Detail from a marble panel from Constantinople, c. 950 CE: an eagle fighting a serpent stands on a hare; some interpret the scene as Christ (eagle) carrying a Christian soul (hare) to Paradise. British Museum
Wiki says to Constantinople: "In the 9th and 10th centuries, Constantinople had a population of between 500,000 and 800,000." So, when this picture "Eagle on Hare" was done, Constantinople had a powerful and strong position ... which it hadn't always.

About Castle Ursino ...
http://www.comune.catania.it/la_cit...rtainment/itinerari/frederick-ii-itineraries/The Ursino Castle is located in the centre of a big square named after Frederick II. Built between 1239 and 1250 the emperor appointed its construction to the architect Riccardo da Lentini, as it is written in a letter dated november 24th 1239 by which the emperor invited the citizens of Catania to pay two hundred ounces of gold, as a contribution to the castle construction. The Catanese people did not like this taxation therefore threatened rebellion.
The Emperor never lived in the castle. Yet, between the end of the XIV century and the beginning of the XV century it became official residence of various kings and their courts, under both the Anjou’s and the Aragonese families. There, Pietro of Aragon held the meeting of the members of the first Sicilian Parliament.
The figure has a rather dominating position, as it seems ...
http://pti.regione.sicilia.it/porta...tineraries2/Castles in Sicily/Castello UrsinoThe entrance is through a pointed archway in the main façade, surmounted by the Swabian coat of arms and an eagle grasping a hare in its talons.
Somewhere I read the interpretation, that the eagle stood for Frederick II and the Hare for Catania. But ... this is just an interpretation.
History has this story about Byzanz and Sicily:
http://en.wikipedia.org/wiki/History_of_Sicily
The Gothic War took place between the Ostrogoths and the Eastern Roman Empire, also known as the Byzantine Empire. Sicily was the first part of Italy to be taken under general Belisarius who was commissioned by Eastern Emperor Justinian I.[7] Sicily was used as a base for the Byzantines to conquer the rest of Italy, with Naples, Rome, Milan and the Ostrogoth capital Ravenna falling within five years.[8] However, a new Ostrogoth king, Totila, drove down the Italian peninsula, plundering and conquering Sicily in 550. Totila, in turn, was defeated and killed in the Battle of Taginae by the Byzantine general Narses in 552.[8]
When Ravenna fell to the Lombards in the middle of the 6th century, Syracuse became Byzantium's main western outpost. Latin was gradually supplanted by Greek as the national language and the Greek rites of the Eastern Church were adopted.[9]
Byzantine Emperor Constans II decided to move from the capital Constantinople to Syracuse in Sicily in 663, the following year he launched an assault from Sicily against the Lombard Duchy of Benevento, which then occupied most of Southern Italy.[10] The rumours that the capital of the empire was to be moved to Syracuse, along with small raids probably cost Constans his life as he was assassinated in 668.[10] His son Constantine IV succeeded him, a brief usurpation in Sicily by Mezezius being quickly suppressed by the new emperor.

From the late 7th century, Sicily together with Calabria comprised the Byzantine Theme of Sicily.[11]
Muslim period
In 826, Euphemius the commander of the Byzantine fleet of Sicily forced a nun to marry him. Emperor Michael II caught wind of the matter and ordered that general Constantine[clarification needed] end the marriage and cut off Euphemius' nose. Euphemius rose up, killed Constantine and then occupied Syracuse; he in turn was defeated and driven out to North Africa.[12]
There Euphemius requested the help of Ziyadat Allah, the Aghlabid Emir of Tunisia, in regaining the island; an Islamic army of Arabs, Berbers, Moors, Cretan Saracens and Persians was sent.[12] The conquest was a see-saw affair; the local population resisted fiercely and the Arabs suffered considerable dissension and infighting among themselves. It took over a century to complete the conquest (although practically complete by 902, the last Byzantine strongholds held out until 965).[12]
Syrakuse (as above described once a possible capital of the Byzantine Empire) is not very far from Catania and castle Ursino ... about 55 km.
Byzanz and Constantinople were under attack in the time of emperor Constans by the expansion of the Arabs, a few years after his death Constantinople was besieged in 5 following years 674 to 678 and again in 717-718.
In c. 950 (time of the first picture) Constantinople was strong again. In 1239-50, when Castello Ursino was build and (perhaps) the Sicilian figure Eagle with Hare was made, Byzanz had been in a downfall. Venice and some crusaders had taken Constantinople in 1204 and a weak Latin Empire was erected, which had its time till 1261, when it was retaken by Michael VIII. Wiki states: "When Michael VIII captured the city, its population was 35,000 people, but, by the end of his reign, he had succeeded in increasing the population to about 70,000 people." Quite a contrast to 500-800.000 inhabitants during the 9th and 10th centuries.
Western Empire had triumphed against Eastern Empire then. "The Eagle had captured the Hare".
*****************
There's a third picture of some interest:

A card from the Tarocco Siciliano and it's the trump No 20, the highest trump of this Tarocchi variant. There's an Eagle, but no Hare.
The motif has a forerunner version, and it looked this way:

There's some agreement, that the second person on the picture presents Ganymed, who was carried by Zeus in the form of an eagle to the Olymp.

Well, it looks, as if this is the Hare.

Well, I don't know, where the idea with Ophiuchus as 13th zodiac sign comes from. Do you, know, what's the origin of this version?
I see in the web, that there are some people having this idea.
http://en.wikipedia.org/wiki/Ophiuchus_(astrology)
... presents some very modern "inventions". That's not my interest. I speak of a German lot book in 15th century, which possibly has older roots.
I think, that I don't desire any confusion between this 13th sign (Ophiuchus) of the zodiac and the other (Corvus), that from the German lot book.
I've also no use for Pookah, which is given as Irish or Celtic folklore figure. Perhaps the simple Easter Hare would do better, at least it might explain, why the Hare in Constantinople in 950 should mean Christ.

I think, we discussed this earlier. You have another view on the number 127 than I have, as far I remember.
But I don't know, what this theme should help in this context.
