Greek kollyra is a coarse cylindrical bread; the diminutive kollourion named the little cake of medicine, gum-bound powders dissolved for application, especially to the eyes, then any eye salve. The witnesses are the best kind: Horace and Epictetus mention it casually, Celsus prescribes it, Lucian describes a seal-forgery compound of the same name, pitch, bitumen, pounded glass, wax, and the Mishnah and Maimonides rule on its Sabbath use. Revelation 3:18 aims the word at Laodicea, home of a famous medical school and its Phrygian eye powder: buy from me salve to anoint your eyes, that you may see. Emerson still used it as a metaphor for clarity in the 1870s.
The Eastern branch of the same art: Sunan Abu Dawood records the recommendation of ithmid, antimony, as the best collyrium, clearing vision and making hair sprout, and the dark eye-shadow sense of collyrium connects the whole file to this archive's Alcohol entry, al-kuhl, the same sublimed antimony powder, the eyeliner that became the word for distilled essence. The eye-medicine and the eye-makeup were one technology on two continents, protection read as beauty and beauty as protection, the pharmacy and the vanity sharing a shelf since the pyramids.
The claim: collyrium is the perfect emblem for this whole project, a soaked bread applied to the eyelid so the patient can see, every entry in this archive functioning as a kollourion, a small cake of compounded sources laid over the eye, Revelation's charge to Laodicea being the research desk's charter: the city had wealth, wool, and the famous eye powder, and was told it could not see. Verdict: the Laodicean irony is documented, the richest eye-medicine market in Asia Minor accused of blindness. The archive applies the diagnosis generally. Every age manufactures its own collyrium and swears by the brand. The salve is bread. The blindness is hunger. Buy the salve, says the letter, from someone who does not sell it.
If the remedy for blindness began as a soaked loaf, what are we currently soaking in what, to see what?
