Assyrian winged dragon

Middle Assyrian seal from Morgan library. Official description: Lion-griffin attacking bull fallen on its forelegs -- Star and sun(?) in sky -- Behind bull, winged sun disk on stand or altar, kneeling worshiper below...

Basically no idea what all this is about...

The bull is the symbol of summer which starts in Taurus (Bull). Summer is symbolised by a bull because it starts with wild Eurasian cattle calving season (late April - early May) and ends with wild Eurasian cattle mating season (late Jul - early August)...

Autumn begins in Leo (lion) Autumn is symbolised by a lion because autumn is the time of the Eurasian lion mating season...

I talked about this in my post "Symbols of the seasons"...

Summer ends in Leo (Lion)...

So lion killing bull is the symbol for summer ending and autumn beginning...

But here we have a winged lion, which is in Mesopotamia one of the ways dragons are depicted...And dragon is a symbol of the destructive sun's heat. Which is most destructive in Leo, the hottest part of the year in the northern hemisphere...

So winged lion (dragon) killing bull is the symbol for summer ending and autumn beginning at the moment of maximum heat...

But this winged lion also has eagle talons...Which means that this "creature" is a mix of lion and eagle...Autumn which starts with Eurasian lions mating season ends with Eurasian vultures mating season...So this "creature" symbolises autumn, which starts when summer ends (dies)...

During the Middle Assyrian period, the time when lion kills the bull was the time when both sun and Sirius were in the sky together...In Leo...Which is why we have the sun and "the star", Sirius, right above the scene of the tauromachy...

This is very important astronomical identification as "the star" is always interpreted as "the star of Inanna, Ishtar" which is never explicitly named but it is "believed" to be Venus (???) Hmmm...

The winged sun...Sun god?
