There is certainly the possibility that there was text superimposed in the image when it was published. There's a lot of empty space for that. That text might put the image into an understandable context.
And you could be right, that it's not for anything scientific and I'm barking up the wrong tree. Maybe it's just a weird painting. Hard to prove a negative. If it were just a weird painting, I might like it even better, but I sense that it is NOT art for art's sake.
