Doesn’t that construction only work in categories that also contain their own morphisms as objects since a profunctor maps (Cᵒᵖ × C) → Set and not the same like (Cᵒᵖ × C) → C? Since the category of Haskell types special, containing its own morphisms, so the profunctor could be like (haskᵒᵖ × hask) -> hask? or I just don’t understand it.

I found it! its the Glagolitic script used in the 9th century before Cyrillic took over:

I don’t think so:

Doesn’t look like it to me:

ልዩ ጊዜ ነበር። አሁን የሚሆነውን ለማስተዋል የኢንተርኔት አውራጃ ማረጋገጥ ነበር።

No that looks like
