Good day, everyone. While I do not have the capacity to participate in this jam, even as part of a group, I do have an idea to offer that could get someone started if they are interested in fantasy, Platonic philosophy, ancient Mediterranean history/cosmology, historical fiction, and/or the idea of the Great Conversation.
(EDIT: I thought perhaps I would connect the dots for anyone who may ask why the hell they should care about this. You cannot taste 'beauty' or 'love'. You may taste something which is beautiful or lovely, but it is not 'beauty' or 'love' which you are tasting; and so it is with the other senses as well. What, then, is absolute beauty or love, unmuddled by the sense-perceptions which only hint at these things? This is the inquiry which drew the ancient philosophers to their craft. How does anyone know what beauty and love are?—surely we must know something about them, if we can call something 'beautiful' or 'lovely'. What then is this pure 'beauty', this pure 'love' of which we speak? These are the same questions that we pursue today, as this game jam attests).
Plato wrote a few dialogues about the nature of love, from different angles and in different contexts. What is most fascinating about Plato is that he not only wrote the foundation of European philosophy, but that he wrote in a narrative style, with unique characters that interact amongst each other. The translation you use may largely determine how organic and lively the interactions appear to be, but it is much more readable and enjoyable than what you might imagine when you think of the word 'philosophy'. (If possible, avoid the translator Benjamin Jowett, unless you enjoy the florid—and, at times, abstruse—literary style of Victorian English).
The most relevant dialogues which were actually written by Plato are the Symposium and Phaedrus, and another one that has been attributed to Plato but most likely came from a later author is called Alcibiades. Alcibiades is a very short read, Phaedrus is a bit longer, and the Symposium is the longest of the three; but with the right type of mindset, any of them could provide a bounty of material for inspiration, adaptation, remixing, or reusing. Possible project ideas could be some of the characters from the dialogues having a follow-up discussion; the rugged exploits of a disciple of Plato, who travels across the ancient Mediterranean proclaiming the doctrine of universal brotherhood; the life and times of a medieval scribe who is copying the dialogue into a new manuscript; an explorer who discovers an ancient scroll containing the dialogue in the sands of the desert or washed up on the seashore; a Renaissance scholar translating the text for their wealthy & politically-powerful patron (such as Marsilio Ficino translating for the Medici family); an occultist attempting to invoke the divine mania of love mentioned in Agrippa's Third Book of Occult Philosophy (a text heavily influenced by the Platonic corpus)... the list goes on.
As I say, this is a free idea for consideration. I suppose I can be a resource for further information if anyone wants to know more and save time on their research. Whether or not anyone uses any of these premises, I look forward to the jam submissions in the days ahead.
