Dunno. Our Phoenixes (Phoenices?) reflect the classical story about a singular bird that resurrects itself by laying an egg in a fire. Seemed natural to the early settlers trying to get started in the heat. This bird is drawn more like an arrow, or sword, and has a snake tongue or perhaps a snake in its beak, so it seems like a different story. Perhaps the "sword" is really a runway. It seems to end in a tunnel under the pyramid. It's interesting to look at it on Google Earth so you can zoom out and see all of Astana.
