Resurrectionists' Excursions: Evidence Of Postmortem Dissection From The Spring Street Presbyterian Church, Shannon A. Novak, Wesley Willoughby Jan 2014

Resurrectionists' Excursions: Evidence Of Postmortem Dissection From The Spring Street Presbyterian Church, Shannon A. Novak, Wesley Willoughby

Northeast Historical Archaeology

In this paper we contextualize two unique individuals recovered from the historic Spring Street Presbyterian Church burial vaults in lower Manhattan (ca. 1820-1846). The crania of one adolescent and one infant display clear evidence of a craniotomy. Both had complete circumferential incisions to remove the calvarium for internal examination. Both crania were sectioned using a saw, though the adolescent underwent further postmortem preparation: thin scalpel marks indicate defleshing, and metal pins embedded in the frontal and occipital bones would have facilitated disarticulation and rearticulation of the vault, presumably for teaching. By the early 19th century, the illicit exhumation of graves …


The Children Of Spring Street: Rickets In An Early Nineteenth-Century Congregation, Meredith A. B. Ellis Jan 2014

The Children Of Spring Street: Rickets In An Early Nineteenth-Century Congregation, Meredith A. B. Ellis

Northeast Historical Archaeology

This paper examines the prevalence of rickets, or vitamin D deficiency, in the subadult skeletal remains from the burial vaults of the Spring Street Presbyterian Church of New York City. The burial vaults of the church were active from approximately 1820–1846 and contain the remains of at least 86 subadults (minimum number of individuals count [MNI] of left tibiae). Over 34% of the subadult tibiae in this collection display pathology consistent with vitamin D deficiency. Since vitamin D is acquired through access to sunlight and specific foods, a high rate of rickets can give clues about living conditions, parenting strategies, …


Archaeologies Of Disease And Public Order In Nineteenth-Century New York: The View From Spring And Varick, William Werner, Shannon A. Novak Jan 2014

Archaeologies Of Disease And Public Order In Nineteenth-Century New York: The View From Spring And Varick, William Werner, Shannon A. Novak

Northeast Historical Archaeology

The authors situate evidence of disease among the burial population of the Spring Street Presbyterian Church within evolving attitudes towards public health and civic order in 19th-century Manhattan. Two personal vignettes illustrate how individuals interacted with the physical space of the church’s vicinity at different moments in the history of municipal reform. The first, a 16-year-old girl named Louisa, was virtually absent from the historical record until the recovery and analysis of her skeletal remains from the church burial vaults. Her skeletal biography conveys the cosmopolitan nature of Manhattan social relations in the early 19th century and the complex ways …


"That Class Of Person Who Cannot Afford A Pew": Analysis Of The Human Remains From The Spring Street Presbyterian Church Burial Vaults, Thomas A. Crist Jan 2014

"That Class Of Person Who Cannot Afford A Pew": Analysis Of The Human Remains From The Spring Street Presbyterian Church Burial Vaults, Thomas A. Crist

Northeast Historical Archaeology

The analysis of the skeletal remains of 85 people interred between ca. 1820 and 1846 in the vaults of the abolitionist Spring Street Presbyterian Church provides unique insights regarding the biological history of antebellum New York City unavailable from other sources. Even though the sample size is small, the remains reflect the prevalence of infectious diseases, metabolic disorders, nutritional deficiencies, premature deaths, and high infant mortality that characterized the rapidly industrializing city. Among the most remarkable discoveries were a rare case of abdominal cancer; a mother and her full-term fetus in utero buried together; two autopsied children; and a dental …

Stories From The Rubble: Analysis Of Mortuary Artifacts From The Spring Street Presbyterian Church Vaults, Rebecca L. White, Douglas B. Mooney

Northeast Historical Archaeology

Archaeological investigations of the Spring Street Presbyterian Church vaults resulted in the recovery of coffin plates, hardware and other burial-related artifacts that convey information regarding the individuals interred within these chambers. These interments also offer a glimpse at mortuary customs and practices in vault burials during the first half of the 19th century.


Lost Within The Rubble: The Archaeological Findings From The Spring Street Presbyterian Church Burial Vaults, Douglas B. Mooney Jan 2014

Lost Within The Rubble: The Archaeological Findings From The Spring Street Presbyterian Church Burial Vaults, Douglas B. Mooney

Northeast Historical Archaeology

Archaeological investigations of the former Spring Street Presbyterian Church property resulted in the discovery of four stone and brick subterranean congregational burial vaults. In active use for only about 25 years, these chambers were found to contain the remains of more than 200 individuals, including large numbers of children. Excavations revealed that remains had been impacted by both natural and manmade processes at various points in the past; however, a total of 46 discrete burials were identified during the excavations. Findings from these investigations provide much previously unavailable information regarding the structure, internal organization, and preservation of remains within 19th-century …


"A Free Church For The People": The History Of The Spring Street Church And Its Burial Vaults, Elizabeth D. Meade Jan 2014

"A Free Church For The People": The History Of The Spring Street Church And Its Burial Vaults, Elizabeth D. Meade

Northeast Historical Archaeology

The Spring Street Church was constructed in the early 19th century to accommodate worshipers in what was then the unsettled area north of the developed portion of New York City. Burial vaults were constructed alongside the church by circa 1820 and were in use for more than 20 years, when changing legislation regarding human burials in Manhattan forced the church to close the vaults. During the period of the vaults’ use, the Spring Street Church members participated in the Abolitionist movement and, as a result of the congregation's promotion of anti-slavery ideologies, the church was demolished by an angry mob …


Introduction: Archaeological And Forensic Investigations Of An Abolitionist Church In New York City, Edward M. Morin Jan 2014

Introduction: Archaeological And Forensic Investigations Of An Abolitionist Church In New York City, Edward M. Morin

Northeast Historical Archaeology

While excavating the foundations for a planned condominium hotel complex in Manhattan, construction crews discovered human remains. The construction staff subsequently ceased excavation and notified the New York City Police Department and the Medical Examiner’s office. Project officials also notified the New York City Department of Buildings and the New York City Landmarks Preservation Commission who requested all excavation be stopped in the vicinity of the remains. Ultimately, the Department of Buildings, the construction permitting agency, determined that all further construction activities be suspended pending the receipt and approval of an integrated work plan for the recovery, documentation and analysis …


From Pork To Mutton: A Zooarchaeological Perspective On Colonial New Amsterdam And Early New York City, Haskell J. Greenfield Jan 2014

From Pork To Mutton: A Zooarchaeological Perspective On Colonial New Amsterdam And Early New York City, Haskell J. Greenfield

Northeast Historical Archaeology

This article analyzes the zooarchaeological remains from historical deposits to increase our understanding of the relationship between diet and ethnicity in early colonial New York City. Excavations at the Broad Financial Plaza recovered faunal remains documenting approximatley two centuries of historical occupation (middle 17th to the middle of the 19th century), a sequence rivaled by few other early colonial North American localities. Several trends are apparent in the data. Relative frequencies of pig remains declined while mutton and cattle increased correspondingly as New Amsterdam became the British colony of New York and as the Dutch residents on the block were …


Pollen Record Formation Processes At The Isles Of Shoals: Botanical Records Of Human Behavior, Gerald K. Kelso, Faith Harrington Jan 2014

Pollen Record Formation Processes At The Isles Of Shoals: Botanical Records Of Human Behavior, Gerald K. Kelso, Faith Harrington

Northeast Historical Archaeology

Exploratory pollen analysis on Appledore Island at the Isles of Shoals, a group of nine islands located approximately eight miles off the coast of southern Maine and New Hampshire, indicates that pollen preservation is excellent in exposed island soil deposits in the temperate zone and that pollen percolation into deposits from surface preserves the record of natural and cultural events where dep cultural deposits have not developed. The Appledore pollen spectra registered the establishment of the resort hotel industry on the island in the mid-19th-century, the virtual abandonment of the island after a major fire in 1914, and the chestnut …


Squeezing Ceramics For More Than Their Worth: Boundary Maintenance At An 18th-Century Port In New Jersey, Rebecca Yamin Jan 2014

Squeezing Ceramics For More Than Their Worth: Boundary Maintenance At An 18th-Century Port In New Jersey, Rebecca Yamin

Northeast Historical Archaeology

Archaeological excavations and associated documentary studies at Raritan Landing, an 18th/19th-century port site on the Raitan River in Piscataway, New Jersey, suggested that the relationship between this small community of traders and New York City merchants changed during the years preceding the Revolutionary War. Diminshing kinship, commercial, and institutional ties between the Raritan Landing traders and New York investors appeared to reflect increasing independence from New York domination over time. When the ceramics recovered from pre-Revolutionary and Revolutionary-period deposits were compared to deposits from several sites in Manhattan and another site within New York, a pattern emerged that has been …


Prospect Hill: Skeletal Remains From A 19th-Century Methodist Cemetery, Newmarket, Ontario, S. Pfeiffer, J. C. Dudar, S. Austin Jan 2014

Prospect Hill: Skeletal Remains From A 19th-Century Methodist Cemetery, Newmarket, Ontario, S. Pfeiffer, J. C. Dudar, S. Austin

Northeast Historical Archaeology

During 1989-90, in response to disruption caused by a building site excavation in Newmarket, Ontario, archaeological and biological information was salvaged from a former church cemetery dating from 1824 or 1827 to 1879. The skeletal remains of 77 indivaduals indicate a population with high infant mortality and little access to medical or dental care. Nevertheless, the autopsy of a young pregnant woman and one gold dental filling indicate there was an incipient interest in biomedical that mechanisms be available to allow the salvage of as much historical and biological information as possible.


Archaeological Excavations At Bon-Désir: Basque Presence In The St. Lawrence Estuary, Dominique Lalande Jan 2014

Archaeological Excavations At Bon-Désir: Basque Presence In The St. Lawrence Estuary, Dominique Lalande

Northeast Historical Archaeology

The archaeological fieldwork on the Anse à La Cave site at Bon-Désir uncovered remains associated with the exploitation of marine mammals in the St. Lawrence estuary. Excavations revealed the presence of two series of ovens used for rendering marine mammal fat. These preliminary data contribute to our understanding of sites based on the seasonal exploitation of whales in North America by European fishermen. The environmental, historical, and archaeological data support the hypothesis of a Basque occupation in the St. Lawrence estuary, particularly on the Anse à La Cave site from perhaps as early as the end of the 16th century …


The Development Of Contact Period Archaeology In Southern New England And Long Island: From "Gee Whiz!" To "Say What?", Bert Salwen Jan 2014

The Development Of Contact Period Archaeology In Southern New England And Long Island: From "Gee Whiz!" To "Say What?", Bert Salwen

Northeast Historical Archaeology

It seems that contemporary archaeologists of the Contact Period continue a long tradition of uncritical acceptance of the written word as "God's truth," to be tested against or to inform the incomplete and necessarily biased archaeological record. When documentary history is available, have archaeologists really progessed so little- from excited discoveries of the antiquarians ("gee whiz") to mere confirmation of written accounts ("so what")? No. This paper argues that archaeologists, working as anthropologists and in conjunction with historians, have been producing new, more critical social analyses of the 17th-century culture contact situation in New England.

The Hale And Keith Mounds In The Big Cypress Creek Basin In East Texas, Timothy K. Perttula Jan 2014

The Hale And Keith Mounds In The Big Cypress Creek Basin In East Texas, Timothy K. Perttula

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

The L. A. Hale (41TT12) and George L. Keith (41TT11) sites are two important ancestral Caddo mound centers in the Big Cypress Creek basin in the Post Oak Savanna of East Texas. Between them, they appear to have been occupied by Caddo peoples between ca. A.D. 1000-1400, although they may not have been occupied contemporaneously. Key questions that I hope to answer in this publication are: (1) when were the sites occupied and when were the mounds on them constructed, and (2) what were the mounds and the sites used for? These questions are challenging because both sites were excavated …


Archaeological Studies Of The Hatchel Site (41bw3) On The Red River In Bowie County, Texas, Timothy K. Perttula Jan 2014

Archaeological Studies Of The Hatchel Site (41bw3) On The Red River In Bowie County, Texas, Timothy K. Perttula
