[DCRM-L] Lemniscate

[Erin Blake]

Turns out Ellen Cordes' question about lemniscate (mathematical symbol for infinity that looks like a sideways 8) used instead of "M" in Roman numeral dates needs more discussion. There's agreement that it should be added to the chart in G2, but not about how to transcribe it.

For background on lemniscate as "M", go to http://www2.inetdirect.net/~charta/Roman_numerals.html and scroll down to "Use of the Apostrophus."

Should a lemniscate be transcribed as "M" or as "[lemniscate]"?

Because DCRM calls for transcribing CI[backwards C] as "M", and a lemniscate is another way to represent the shape of CI[backwards C], I assumed it would be transcribed "M" (and you could make a note that a lemniscate is used). [Note: an explanation for transcribing CI[backwards C] as M can be found in the DCRM-L archives at https://listserver.lib.byu.edu/pipermail/dcrm-l/2006-January/000980.html  where Deborah J. Leslie writes "there there is an historical relationship between the apostrophic and modern forms of M (CI-backwards C) and D (I-backwards C). This provides us with strong support in the decision to transcribe apostrophic Roman numerals in their modern Roman equivalents."] 

However, it could also be a case of "replace symbols or other matter that cannot be reproduced using available typographical facilities with a cataloger's description in square brackets" so the date field would read, for example, "[lemniscate]DLXVII [1567]" 

Your input is needed!

Thanks,

   EB.

It is no more obscure than some of the Latin symbols. Add it.

Hi Erin,

I don't recall it ever coming up in discussions, so I think it wasn't
a deliberate omission.

I'd vote for adding it to the chart!
