The other day I came across the word “eidolon/eidola” (singular/plural), Greek for a look-alike phantom for a person, in their case, especially applied to Helen of Troy. [And in Greek letters: εἴδωλον].
The Guru and I are binge-watching a Canadian TV series called “Continuum,” which has character duplicates, which I think can be called eidola.
Too many doubles. Here’s a single purple fleur; buds don’t count—my rules.
