I recently re-read A Game of Thrones by George R.R. Martin, and at a certain point one of the characters mentions a legendary knight whose name seemed purposefully similar to a real historical figure.
“‘There was a knight once who couldn’t see, ‘ Bran said stubbornly, as Ser Rodrik went on below. ‘Old Nan told me about him.’…’Symeon Star-Eyes,’ Luwin said as he marked numbers in his book. ‘When he lost his eyes, he put sapphires in the empty sockets, or so the singers claim.” (pg. 730)
It might be a coincidence, but that reminded me of Simon bar Kokhba. I don’t think Martin is Jewish or anything, but the reference to placing sapphires in the eyes could be taken as being blinded by greed or ambition. Who knows, but I thought it was interesting.
