    1. Are there symbols for 'supported by' or 'contradicted by' etc. to show not quite formal logical relations in a short hand?

      In addition to the other excellent suggestions, I don't think you'll find anything specific that that was used historically for these, but there are certainly lots of old annotation symbols you might be able to co-opt for your personal use.

      Evina Steinova has a great free cheat sheet list of annotation symbols: The Most Common Annotation Symbols in Early Medieval Western Manuscripts (a cheat sheet).

      More of this rabbit hole:

      (Nota bene: most of my brief research here only extends to Western traditions, primarily in Latin and Greek. Obviously other languages and eras will have potential ideas as well.)

      Tironian shorthand may have something you could repurpose as well: https://en.wikipedia.org/wiki/Tironian_notes

      Some may find the auxiliary signs of the Universal Decimal Classification useful for some of these sorts of notations for conjoining ideas.


      Given the past history of these sorts of symbols and their uses, perhaps it might be useful for us all to aggregate a list of common ones we all use as a means of re-standardizing some of them in modern contexts? Which ones does everyone use?

      Here are some I commonly use:

      Often for quotations, citations, and provenance of ideas, I'll use Maria Popova and Tina Roth Eisenberg's Curator's Code:

      • ᔥ for "via" to denote a direct quotation/source— something found elsewhere and written with little or no modification or elaboration (reformulation notes)
      • ↬ for "hat tip" to stand for indirect discovery — something for which you got the idea at a source, but modified or elaborated on significantly (inspiration by a source, but which needn't be cited)

      Occasionally I'll use a few nanoformats, from the microblogging space, particularly

      • L: to indicate location

      For mathematical proofs, in addition to their usual meanings, I'll use two symbols to separate biconditionals (necessary/sufficient conditions)

      • (⇒) as a heading for the "if" portion of the proof
      • (⇐) for the "only if" portion

      Some historians may write 19c to indicate 19th Century, often I'll abbreviate using Roman numerals instead, so "XIX".

      Occasionally, I'll also throw drolleries or other symbols into my margins to indicate idiosyncratic things that may only mean something specifically to me. This follows in the medieval traditions of the ars memoria, some of which are suggested in Cornwell, Hilarie, and James Cornwell. Saints, Signs, and Symbols: The Symbolic Language of Christian Art 3rd Edition. Church Publishing, Inc., 2009. The modern day equivalent of this might be the use of emoji with slang meanings or 1337 (leet) speak.

    1. Early Christians used the ichthys, a symbol of a fish, to represent Jesus,[94][95] because the Greek word for fish, ΙΧΘΥΣ Ichthys, could be used as an acronym for "Ίησοῦς Χριστός, Θεοῦ Υἱός, Σωτήρ" (Iesous Christos, Theou Huios, Soter), meaning "Jesus Christ, Son of God, Saviour".

    1. side from hunting scenes, one may broadly divide ancient depictions of hares into two iconographical groups. In the first group, the hare embodies the love of a man for a woman. On numerous Greek vases, for example, we see a depiction of Eros, the God of Love, with his two symbols, the lyre and the hare; other scenes show Eros pursuing a hare as a symbol of love, which, as we know from Book 1 of Philostrates’ Imagines, has been given a special gift: fertility.
