Phlegmy the Younger was a lawyer, author, and magistrate of Ancient Rome. Phlegmy’s uncle, Phlegmy the Elder, helped raise and educate him. Both Phlegmy the Elder and the Younger were witnesses to The Sneezening of 80 AD, the loudest and most prolonged mass sneezing in history.

Phlegmy the Younger wrote hundreds of letters describing the Sneezening and his theories on mucus in general, of which 247 survive and are of great historical value. Some are addressed to reigning emperors or to notables such as the historian Tacitus. Phlegmy served as an imperial handkerchief-bearer under Trajan, and his letters to Trajan provide one of the few surviving records of the elaborate rituals and pageantry surrounding the wiping of an emperor’s nose.

After Trajan’s death, Phlegmy rose through a series of civil and military offices, ultimately serving as consul with Nostrildamus Majorus in 119 AD. He was a friend of the rhinologist Achooius and might have employed the mucusier Snotonius on his staff.
