"The Milk of Birds": A Proverbial Phrase, Ancient and Modern, and its Link to Nature

A curious phrase from ancient Greek, ὀρνίθων γάλα, finds parallels in Latin as lac gallinaceum and in Modern Greek, as και τοσ ποσλιού το γάλα. While the Greek phrases translate as "(and) the milk of (the) bird(s)", the Latin translates as "henʼs milk". This essay discusses the phrase in a select variety of Greek and Latin sources from the 5th century BCE to the 4th century CE, and its Modern Greek equivalent in the 21st century. In addition, it discusses the variety of meanings and uses found in those sources, and connections to the natural world. Information from ancient sources has been gleaned from a search of the Digital Loeb Classical Library online database. Information for modern use comes from informal interviews, Facebook messages, e-mails, and telephone messages of nine native speakers of Modern Greek from different parts of the Greek world, most of whom live in the United States. The essay discusses two points concerning the natural world: first, the phrase as found in the names of certain plants, and second, as a substance called crop-milk produced by members of the pigeon family. The linguistic connection between ancient and modern worlds and the parallels found in nature encourage scholars to look "outside the box" when investigating proverbs, proverbial expressions and proverbial phrases. The Modern Greek version of the phrase both confirms and expands the meanings of the ancient ones, thus suggesting that other connections between these ancient and modern languages may prove to be fruitful avenues of investigation.
