From August-October, archaeologists from John Milner Associates (JMA) explored the site where the Museum of the American Revolution will be built. The excavation phase is over, but the analysis has only just begun! Lead archaeologist Rebecca Yamin is back with new discoveries being made in her group’s lab:
Since finishing excavation on October 24th, we have been busy cleaning, organizing, and inventorying the artifacts in our West Chester laboratory. About 60,000 artifacts have been entered into a computer database and we are beginning the mending process. When possible, found fragments are mended together to form the vessels they used to be—cups, plates, glasses, flower pots, etc.
Our last field report announced the discovery of the Success to the Triphena punch bowl. Many more sherds have been found in the lab and when taped together they form an almost complete bowl. We’ve also pieced together some beautiful redware plates made by Philadelphia potters who we will make every effort to identify. A surprise artifact that we didn’t notice when it was covered with dirt in the field included a bottle seal bearing the initials “S. M.,’ probably for its owner, Sarah Merrick, who lived at No. 32 Carter’s Alley in 1791. (The punch bowl was found next door at No. 30.)
In addition to mending artifacts, another part of the analysis process is tracing the owners and occupants of the properties where the artifact-filled features (privies) were found. Fortunately, many primary documents with this information, including deeds and directories, are now online, but we will also be visiting the City Archives and the Historical Society of Pennsylvania. So far, from deeds we have learned that the block was occupied by many different kinds of artisans. For instance, in the 1790s there was a shoemaker, a bookbinder, a printer, a carpenter, a paper manufacturer, a blacksmith, a stay maker, a tallow chandler, a coachmaker, a cutler, and a cordwainer on Carter’s Alley. A clerk in the Treasury department lived at No. 76 Chestnut Street in 1794, which would have been convenient to the First Bank of the United States located on the other side of Third Street. A shoemaker and cordwainer were at that address a few years earlier and a gilder was there in 1810. It will be interesting to see if any artifacts relating to these particular occupations turn up in the lab.
Once the artifacts are mended we will match them to their probable owners and address research questions that relate to domestic life in early Philadelphia and industrial activities that co-existed with private houses in this neighborhood. The site includes a material record of the development of the city in microcosm and we will trace the changes over time from the late 17th century up to the second decade of the 20th century.
Pictured above (from top) are two images of archaeology team members piecing together artifacts; a more complete look at the Success to the Triphena bowl from the inside and the outside; an assortment of sherds; and a beautiful example of Philadelphia redware.
We’re looking forward to hearing more about the team’s findings in the new year. Many thanks to Rebecca and her team for their hard work and to you for following along!
