Free Map of california free for Because comets are not point sources but rather extended objects, technically they heliacally rise over a period of time, like constellations. In ancient Babylonian and Chinese comet reports, however, the focus was on the coma or head that is, the sunward part of the comet and hence a report of a comet’s heliacal rising would most naturally refer to its coma. Of course, the date of a heliacal rising was strongly dependent on the weather. It seems clear that anatole in Matthew is referring to a heliacal rising rather than a standard nightly rising. The fact that the Magi even mention the context of the Star’s display at its rising strongly favors the view that this is significant information that played a key part in their assessment of the astronomical phenomenon.

Moreover, since the Magi and Matthew, the narrator employ the possessive article at its rising it is evident that a distinctive occasion in the Star’s career is in mind.
