During the early modern period, the city of London produced weekly mortality reports called bills of mortality. These bills—printed from 1603 onward—detail the number of deaths per parish; plague deaths per parish; and deaths citywide by cause of death. However printed bills were actually summaries of manuscript bills produced for the monarch, which contain a parish-by-parish breakdown of every cause of death throughout the city of London for the preceding week.

At about 3am on Sunday, September 2, 1666, the diarist Samuel Pepys’ maid Jane awakened him to let him know about a fire that had started within the ancient city walls of London. He looked out the window, thought it was too far away to worry about, and went back to sleep. When he got up the next morning, Jane relayed the news that over 300 houses had already burned, so he went to the Tower of London and climbed to a high spot where he could see the extent of the threat: “an infinite great fire”1 which would rage for four days before being reduced to embers that ominously smoldered in cellars for several more weeks.

PI Jessica Otis will be presenting on Death by Numbers at the annual meeting of the Renaissance Society of America this week. For anyone attending the meeting, the presentation will be Friday, March 10th, from 4:30-6PM in the Caribe Hilton Gran Salón Los Rosales A - Gran Salón Los Rosales (Garage). Free notebooks and stickers with the project logo will be available for anyone who wants one. Figure 1. Our new swag!

Welcome to the relaunch of our blog and the formal beta launch of the Death by Numbers database. While our blog has been quiet, we’ve been busy behind the scenes getting our code squared away and finishing transcribing some of the early datasets so that the project was in a good place for a public debut. We’re still hard at work adding data to the database and building our first visualizations, so don’t be surprised at how large some of the gaps are in the dataset.

In late November of 1703, a “great storm” or hurricane struck the British Isles. Bad weather began a few days before the heart of the storm made landfall on November 26th, spawning tornadoes, ripping off roofs and chimneys, and destroying entire fleets. One of the most famous tragedies of the storm happened on the Goodwin Sands, a deadly sandbank off the coast of Kent. At least 53 ships were wrecked on the sandbank and over 2,000 men died just six miles from safety.

The London Bills of Mortality were originally and primarily focused on deaths from plague, however they very quickly expanded to include other causes of death as well. From accidents and drownings to measles and smallpox, the printed bills included citywide summary statistics—rather than parish-by-parish breakdowns—for each week. While we can therefore learn a fair amount about causes of death throughout the city, very little information can be gleaned from the sixteenth- and seventeenth-century bills about the age at which people died.

The Bill of Mortality from Christmas week in 1664 reports that three people died in the parish of St Foster. But fifty years later, there were happily no Christmas deaths in the parish of St Vedast—or rather, the parish of “St Vedast alias Foster.” Because the parish of St Vedast is the parish of St Foster. Welcome to the complex world of early modern parish names. Given that our sources were published over the course of centuries, it’s hardly surprising that the names of some of the parishes in the bills changed over time.

One of the more helpful digital databases for the study of early modern history is Early English Books Online (EEBO), which contains images of most of the surviving books printed in England between 1473 and 1700. It builds upon the cataloging work of 19th-century bibliographers and began its life as a collection of microfilm in the late 1930s and 1940s before being digitized at the turn of the twenty-first century.1 Because its focus is on books rather than broadsides or bills, EEBO only contains a small fraction of the early modern Bills of Mortality but a keyword search for the bills still turns up almost 500 results.

The main organizational unit behind the London Bills of Mortality is the parish: a religious administrative unit usually consisting of one or more churches, their associated staff, and all Christians living within the geographical bounds of the parish. The parish clergy christened, married, and buried their parishioners and—starting in the sixteenth century—the parish clerk kept a register of those events. The burial numbers would eventually form the basis of the bills, with christenings added later.

One of the first things a Bill of Mortality tells the reader is the date. The bill (partially) pictured below covers mortality data for the city of London, in the 3rd week of the current bills’ year, which ran from the 31st of December to the 7th of January in the year 1700 AD (from the Latin, Anno Domini, which was often translated into English as the Year of the Lord).

Plague epidemics were a recurring threat in late medieval and early modern Europe. While plague could and did strike anywhere, the most well-documented epidemics were often in cities. Responses varied across time and space, as city leaders and other political authorities attempted to avoid contagion, contain the sick, and understand the scope of the threat plague currently posed to their lives and their livelihoods. These responses included the creation of lists: lists of people sick with plague, lists of cities infected with plague, and–starting in the sixteenth century–lists of the number of people who had died of plague.
