The Bulls of Aeetes

The Khalkotauroi (Bronze Bulls) aka Colchis Bulls were a pair of automatons created by Hephaestus for Aeetes, King of Kolkhis (Colchis). The bronze bulls were described as having feet of bronze and bronze mouths from which they breathed out flame.

I think de Troy missed the part about the bulls being automatons

There is also a tradition that portrays Talos (typically described as a giant automaton in the form of a man) as having the form of a bull.

Both the the Khalkotauroi and Talos play roles in the myth of Jason and the Argonauts. In the 1963 Ray Harryhausen verion of Jason and the Argonauts, Talos appears, but there are no bulls. In the Jason and the Argonauts TV miniseries from 2000 only a single bull appears.

CGI "Menaian" Bull

To represent the Khalkotauroi, I originally wanted to use a pair of Warhammer metal Juggernauts.

After getting one model, I felt that the Juggernaut was too big. It has a very bull-like body, but modifications need to be made to the model. The main change would be to remove the nose horn, and add some bull horns.

Later, I discovered that Wargames Foundry also produced a Bronze Bull (WG434), which seems to be based on the Menaian Bull from the miniseries.

The Foundry bull is smaller than the Juggernaut, and just the size I had in mind for a bronze bull. The only issue I have with it is that it does not have a tail (but that is easily remedied).

I was also finally able to get the Bronze Bull produced by Crocodile Games for their WarGods of Olympus Kickstarter campaign.

The Bronze Bull consists of 5 parts, and goes together fairly easily. I think the tail is actually supposed to go into the body before you glue the two halves together. I added it after gluing the body, because the tail broke off of the attachment, so the order didn't really matter. 

The Crocodile bull is really nice, but it is longer and heftier than the Foundry bull, so they don't work well as a pair. I will need to buy another Foundry model if I want to make my paired set.

The Golden Fleece

Lord Jason held up the great fleece in his arms. The shimmering wool threw a fiery glow on his fair cheeks and forehead... The ram's skin with its golden covering was as large as the hide of a yearling heifer... The long flocks weighed it down and the very ground before him as he walked was bright with gold... Dawn was spreading over the world when they rejoined the rest. The young men marveled when they saw the mighty fleece, dazzling as the lightning of Zeus...

– Argonautica

The Golden Fleece is the pelt of the Golden Ram who took Phrixus across the Aegean and Black Seas to Colchis, and was immortalized as the constellation Aries.

The Fleece is also part of the legend of Jason and the Argonauts, which Strabo interpreted as a mythologization of the gold panning technique used in Colchis (a theory still popular to this day).

There are different versions of the legend describing how Jason overcomes the dragon guarding the Golden Fleece to attain the prize.

The Colchian Dragon guarding the Golden Fleece is described as both deathless and unsleeping, yet in the legends it is either put to sleep by Medea, or killed by Jason.

For miniatures, the Golden Fleece is available from Crocodile Games (WarGods of Olympus WGO-121b), while the Colchian Dragon is available from Mythic Battles: Pantheon by Monolith Games.

I was a bit unsure about the exaggerated curves of the Dragon, but it does look like a somewhat flattened representation of the corkscrew appearance of dragons in ancient Greek art.

The model of the Golden Fleece is excellent, but I cut away the helmet that was attached to the tree bearing the Fleece since it was too big, and I couldn't really find a reason for it to be there. The miniature was then primed, and the Fleece painted gold.
