I'm not really sure, but for now -1 to another tag, just tag it sun_(symbol) and personification, unless maybe if you find more examples.
I would've gone with sun (personification), but that's only because I haven't really come across the word "herald" much before. Would you suggest implicating it if we did go with a tag?
- Create implication sun_(herald) -> sun_(symbol)
- Create implication sun_(herald) -> personification
