Arcanum

How Arcanum began

Arcanum was platted in 1849 in Twin Township, southeastern Darke County, by John Gunder ('Gunder' in the 1880 county history); its unusual name was chosen in November 1848 by two engineers hired by Gunder, who picked the Latin word 'arcanum,' meaning secret or hidden mystery. Samuel and John Smith opened the village's first store on June 20, 1851, and the arrival of the railroad from Dayton the following year transformed the young village, ending the long, expensive haul to market by corduroy road. By 1880 Arcanum had grown to about 1,000 people with four dry-goods houses, two flouring mills, a printing office and an eight-room school -- one of the most substantial villages in the county's southern townships.

Settled 1849, platted 1849, by John Gunder.

Where the name comes from

Chosen in November 1848 by two engineers commissioned by founder John Gunder; they picked the Latin word 'arcanum' (secret, hidden mystery) because the site was not yet on any map, a choice said to suit the dark, foggy weather of the day.

Before the town

No Native American village, trail, or site specific to present-day Arcanum is documented in the sources checked. The village sits in southeastern Darke County, part of the broader Miami and Shawnee homeland ceded under the Treaty of Greenville in 1795, more than fifty years before Arcanum was founded.

Stories

A name picked for what it hid

When John Gunder set out to found a town on this stretch of southeastern Darke County farmland in the fall of 1848, he hired two engineers to survey and name the site. According to the story the village still tells about itself, the two men settled on 'Arcanum,' the Latin word for a secret or hidden mystery, in part because the spot did not yet appear on any published map -- it was, in that literal sense, unknown -- and in part because the choice seemed to fit the dark, foggy November weather on the day they picked it. The name stuck through the village's founding the following year and the railroad's arrival in 1852, giving one of Darke County's smaller villages one of Ohio's more distinctive place names.

A railroad that raised the price of horses

Before 1852, getting produce to market from Arcanum meant a long, tedious and expensive wagon journey through swamps and over corduroy roads to Dayton. When the railroad finally reached the village that year, cutting diagonally across Twin Township, the 1880 county history singles out one unexpected effect among the obvious ones: it 'increased the price of horses,' to the surprise of many residents, even as it also opened a real market for local produce for the first time. By 1880, that one connection had helped grow Arcanum from Samuel and John Smith's single 1851 store into a village of about 1,000 people supporting four dry-goods houses, seven groceries, two flouring mills, a printing office, and an eight-room schoolhouse with four teachers -- among the more substantial villages anywhere in the county's southern townships.
