Seasonally appropriate, perhaps you know Giotto’s Adoration of the Magi. The star of wonder looks like a comet to me. Europe’s 1980’s probe to Halley’s comet was named for him, because of this painting. Giotto was thought to have been inspired by that ice ball’s 1301 approach near Earth. Perhaps it was the sign for the mysterious Gentiles from afar, and not a star after all.
If you want a really good view of Halley’s Comet, your choices would seem to be the Scrovegni Chapel in Padua or the year 2134. Meanwhile, a blessed Epiphany to all readers, wherever in the solar system you are wandering.
