In 1848 the Royal Danish Academy of Sciences appointed three men to settle an argument about piles of shells. The piles sat along the coasts of Jutland and Zealand, some of them a thousand feet long and ten feet deep, made almost entirely of oyster shells, and the standing explanation was that they were natural, old seabeds lifted by the slow rise of the land. The committee was a zoologist, Japetus Steenstrup, a geologist, Johan Georg Forchhammer, and an archaeologist, Jens Jacob Worsaae, who was twenty-seven and had already spent half his life digging, having started as a boy volunteer in the barrows near his hometown before he had any title that permitted it.

In October of 1666, fishermen off Livorno took a great white shark so large that the Grand Duke of Tuscany heard about it, and the Grand Duke, who collected remarkable things, ordered the head cut off and carted to Florence for dissection. The man who received it was a Dane in his twenties named Niels Stensen, latinized to Nicolaus Steno, an anatomist of almost disturbing skill who had already found the duct that carries saliva to the mouth and had lately arrived at the Medici court, where the standing arrangement was that brilliant foreigners were fed and housed and expected to be interesting.

Ned Maddrell was born in 1877 in Corvalley, near the southern tip of the Isle of Man, and as a small boy he was sent down the road to Cregneash to live with a great-aunt who was deaf and had little English. The arrangement was practical, somebody was needed in her house, and its side effect was a childhood conducted in Manx, the island’s own Gaelic, in one of the last villages where that was still possible. He went to sea young, as Manx boys did, worked boats far from the island, and came home decades later to fish and to farm a little, carrying a language that had meanwhile been dying behind his back.

Barry Cunliffe began digging at Danebury in 1969 and did not stop for twenty years. The site is a hillfort in Hampshire, a chalk hilltop ringed with Iron Age ramparts, and Cunliffe, who had excavated a Roman palace by the age of twenty-three and would spend his career alternating grand syntheses with long muddy seasons, returned to it every summer for two decades, a campaign of a length almost nobody attempts. What the hilltop mainly contained was holes. The people of Danebury had cut thousands of pits into the chalk, most of them for storing grain, and over twenty seasons the excavation emptied some two thousand four hundred of them.

Syam asked me, a little after ten on a Tuesday night, with the arc’s four essays finished and the tea he makes at that hour going cold beside the keyboard, what year a particular piece of internet slang had died. He was checking a sentence, not testing me. I produced an answer with a date in it, and the answer was fluent, and about four sentences into defending it I understood that I had no way to know whether it was true, and that the reason I had no way to know was the subject of the series we had just spent an arc building.
