The flower-like Hawaiian "Cross of the Goddess Marama" on the left is very similar to an astronomical drawing of a (hypothetical) cross-like pattern in the Sun's corona on the right. The Sun's corona usually appears like a gigantic flower in the sky, and it sometimes displays a cross-like aka cruciform pattern that inspired solar cross symbols.

Could you post photos of the two ceramic sherds with polychrome flowers & the other sherds that might have palm fronds or wings depicted on them?

I might be able to clarify.

It's possible that the "flowers" & even the "wings" are #SolarSymbols inspired by #TotalSolarEclipses.
