I can’t claim I understand Terry Hays’ work, not even a little bit. But the Christian-ish allegory with an Eastern flair of the above is striking. Those flames at the upper right look like they could have been spewed by these sorts of demons. The ichthus design residing in some sort of creature accompanying our swimmers might guide, support and propel them, given their locations. But although those arrows suggest the current is against the swimmers, where is salvation? The swimmers do not seem to exist outside of the water. The left half of the panel glows with something brighter, interspersed with what remains of where the swimmers were. It looks curiously like the land masses one might see on a map.
The other works on his site are definitely worth perusing: “Grass Fire” has my attention at the moment.
