Which Mythology is in fashion?

[Astromancer]

In the West, Greek and Roman myths dominated literary fashion from the 6th century until the 19th. In the mid 19th century the Norse myths were more fashionable for a while with Hindu/Vedic and Egyptian myths along with the resurgent Greek myths joining to contest dominance in the 1880-1935 period. Greek came back to dominance with WWII and Celtic myths have challenged them since the 1960s. My question is, which mythology is the literary fashion in Transhuman Space?

We know there is an orbital amusement park with a Greek myth theme around Mars, but that shows continued popularity not cultural dominance. Which mythology is the cluster of stories Transhuman Space speaks about itself with?
