It’s a real word, referring to the study of fish in the past, as detailed in a recent Atlantic article:

The Medieval Practices that Reshaped Europe’s Fish

In Europe, aquatic animals have been traded at least since the days of the Roman Empire. But it was during the early Middle Ages, with the arrival of widespread Christianity, that the animals became a popular source of protein. That’s partially due to the roughly 130 days a yearwhen the faithful were exhorted not to eat meat, because fish didn’t count in that category.

At the same time, expanding agrarian populations were cutting down forests to create fields and diverting rivers to fill defensive moats around castles and towns, Hoffmann writes in one paper. From the ninth century a.d. to the 11th, the number of grain mills built along rivers in England exploded from about 200 to 5,624. Species that came into fresh water to spawn, such as salmon and sturgeon, began declining. New regulations, such as King Philip’s, were put into place to manage fish populations. A Scottish statute from 1214 required all dams to include an opening for fish and barrier nets to be lifted every Saturday, for instance. Soon highly sophisticated aquaculture ponds stocked with carp also provided regular access to fish for the landed elite.

This decline in freshwater populations coincided with a sudden, commercial-scale boom in sea fishing, which began around a.d. 1000 and is known as the “fish event horizon.” In one study, archaeologists collected cod bones in London from 95 Roman, medieval, and postmedieval sites. The number of bones jumped circa the year 1000, and isotopic sampling showed that in the following centuries, fish came from farther and farther away, indicating long-distance trade. In the southern English town of Southampton, the remains of marine species (such as cod) began to outnumber freshwater species (such as eel) by 1030.

That “fish event horizon” could have been caused by a number of forces. It came at a time of population growth, urbanism, new ship technology, and increased trade, says the archaeologist James Barrett, from the University of Cambridge. But, he adds, “I’ve argued consistently that this must also be about human impacts on freshwater and migratory fishes. The degree of vulnerability of fishes depends on how bounded the ecosystem they occupy is.”

In other words, because their habitat was smaller, freshwater fish were more likely to respond to human pressures sooner. When the reliable stocks of freshwater fish began dwindling, hungry Europeans turned to the much larger oceans. And while those populations had larger ranges, humans still had an impact.

Medieval Dragons

Seven Things You Didn’t Know About Medieval Dragons

1. Medieval people understood what a “dragon” was.

I say dragon, and you visualize a giant fire breathing, flying lizard with legs, maybe claws, maybe a voice. I know, and you know. Dragons are that iconic a cultural image. The same was true of the Middle Ages. As Paul Acker showed, Norse sagas spend basically no time describing the physical characteristics of their dragon foes—despite the physical form of the dragon being crucial to the hero’s contest against it and the audience’s ability to follow the battle.

2. Or rather, medieval people understood what dragons, plural, were. 

In the thirteenth-century Norse poem Fáfnismál, Sigurd digs himself a pit where he knows the greedy dwarf-turned-dragon Fáfnir will slither. Our hero stabs upwards into the dragon’s belly. This feat makes no sense to an audience expecting a monster who lumbers on legs or takes to the skies. Just like we “know” what a dragon is from general cultural awareness, medieval people knew.

Fáfnir is, for all intents and purposes, a giant snake. He spews clouds and rivers of venom like a giant snake. A frequent attribute of dragons in medieval bestiaries (descriptions of animals and their characteristics meant as moral lessons for people) recounts their ability to kill animals as large as elephants via constriction and suffocation… you know, like a giant snake. But nobody blinks when Chretien de Troyes’ great dragon in Yvain is “so full of evil that fire leapt from its mouth,” or when the Norse adaptation of Chretien’s Arthuriana lets its dragon dispense with the cooking and get right to the eating. Sometimes dragons are specified as flugdrekar – flying dragons – and sometimes simple drekar and ormar (“worms”) are described as taking to flight. What medieval people understood by “dragon” was a much wider range than the color-coding schemes of modern fantasy. Which brings us to the most excellent variety of medieval dragon:

3. Before they acquired the ability to fly, medieval dragons dropped out of trees onto people’s heads.

As Pliny the Elder’s Natural History, an important source for medieval encyclopedic and bestiary writing, has it:

The iaculus throws itself from the branches of trees; dragons are dangerous not only to the feet but also fly like a missile from a catapult.

Isidore of Seville in the early seventh century clarified that the iaculusindeed takes its name from the javelin, and the Norse Rómverja sagadraws out this point in excruciating detail:

struck under the cheek that man who was called Paulus and the serpent flew straight into his head and out of his cheek

Mummified cats, British Museum. Wikipedia.

An excerpt from The Histories of Herodotus, illustrating the ancient Egyptian affinity for cats:

What happens when a house catches fire is most extraordinary – nobody takes the least trouble to put it out, for it is only the cats that matter: everyone stands in a row, and a little distance from his neighbour, trying to protect the cats, who nevertheless slip through the line, or jump over it, and hurl themselves into the flames. This causes the Egyptians deep distress. All the inmates of a house where a cat has died a natural death shave their eyebrows… Cats which have died are taken to Bubastis, where they are embalmed and buried in sacred receptacles. (Book 2:66-67, trans. Aubrey de Sélincourt).

Every now and then they uncover a cache of cat mummies, including at Bubastis, which by the time of the New Kingdom was indeed sacred to the cat-headed deity Bastet.


We saw a great exhibit about Egyptian cats at the Carlos Museum last fall. Here is the cover of the exhibit catalogue. Unfortunately there were no cat mummies on display.
