The PECO Crown Lights Archaeology Month Message

WHAT IS THIS MESSAGE ABOUT?

October is Pennsylvania Archaeology Month. For Pennsylvania Archaeology Month 2011, two 30-second public Service Announcements, or PSAs, have been created to run on the PECO Building’s Crown Lights marquee. One announces the Explore Philly’s Hidden Past! archaeology event that takes place October 1st. A second message celebrates the Governors designation of October as Pennsylvania Archaeology Month. (There are two versions of this latter message featuring 2 different objects.)

These PSAs are designed to generate awareness of archaeology among the broader community. The PSAs were created at the request of the Philadelphia Archaeological Forum by students and faculty from Drexel University. Producing these messages leveraged local archaeological research and local computer science and media arts expertise.

WHAT’S THAT TWIRLING ON THE PECO BUILDING?

IT’S A PLATE! IT’S A BOWL!

The Archaeology Month messages features archaeological objects that were excavated from the city of Philadelphia:

This is a small, hand-painted, pearlware saucer manufactured sometime between 1780 and 1820. The plate was manufactured in England and was purchased in a shop somewhere likely here in Philadelphia. This dish would be typical middle class tableware in its day. Archaeologists discovered this item in Independence National Historical Park during the construction of the National Constitution Center.
This is a small plate with a blue transfer-printed decoration. This dish would likely have been part of a matched set of dishes. In the early 19th century this style of tableware was fashionable and somewhat pricey. Fragments of this dish were discovered in Independence National Historical Park during archaeological work done in advance of the construction of the National Constitution Center.
Archaeologists call bowls that are decorated with bands of color like this either ‘dipt’ or ‘annular ware’. This bowl may have been used both when preparing food and when eating or consuming food (most likely soups, stews, and or porridge). The type of decoration indicates to the archaeologist that this bowl is not an expensive item. It was discovered by archaeologists in Independence National Historical Park during the construction of the National Constitution Center. (This bowl and others like it from the same site are on display at Wintethur Museum. Learn more about that exhibit.)

These three objects are just a few of the approximately 1 million artifacts discovered at the site of the National Constitution Center when that building was being built. These artifacts are evidence left behind by those who lived in Philadelphia during the early years of our nation. This archaeological evidence has many stories to tell us. All of these artifacts are taken care of for the American people by Independence National Historical Park.

HOW WERE THE PSA’s MADE?

The PSAs bring together science, art and technology. A 3D reconstruction of an artifacts found at the National Constitution Center archaeology site begins each of the PSAs. The artifacts were recovered by a team of archaeologists supervised by the National Park Service between 2000 and 2003. The 3D artifact reconstructions were created by Drexel University Computer Science Ph.D. student Geoff Oxholm. Oxholm has designed cutting edge software that virtually reconstructs historical artifacts. His work is part of a Drexel University-based, computational archaeology research project funded by the National Science Foundation: (Grant Award No. 0803670) The 3D Colonial Philadelphia Project — Digital Restoration of Thin-Shell Objects for Historical Archeological Research and Interpretation.

Drexel University undergraduate students Hannah Winograd and Mathew Hass, and Digital Media Masters student Mark Petrovitch, converted this scientific data to make it compatible with design software. Winograd and Haas animated the artifact reconstructions using Adobe Premier and joined them with the PSA text created using Adobe Photoshop. Haas and Winograd’s production was supported by Drexel University’s Pennoni Honor’s College Students Tracking Advanced Research (STAR) Fellowship Program and the Digital Media Program of the Antoinette Westphal College of Media Arts and Design. Their work was supervised by STAR mentors and NSF Co-Principle Investigators, Glen Muschio, Associate Professor, Animation and Visual Effects Program, and Visiting Research Professor Patrice Jeppson, Westphal College. Mr. Hass and Ms. Winograd worked in close association with Mr. Oxholm to produce the 30 second PSAs.

PECO projects the PSA messages from a 40 foot high marquee of lights that encircles the top of the company’s headquarters building in downtown Philadelphia. This means the Archaeology Month message is 27 floors up in the sky! The messages run along side other messages from sundown to sunrise via 2 million LEDs, or light-emitting diodes. The messages make Philadelphia's contribution to Pennsylvania Archaeology Month unique and special.

ACKNOWLEDGEMENTS

The Philadelphia Archaeological Forum thanks PECO for running public service announcements in support of Pennsylvania Archaeology Month 2011 on their PECO Crown Lights system. A giant thank you to Drexel University students and faculty for creating the animated Archaeology Month messages projected by the PECO Crown Lights system.

Archaeology in Independence Park
Explore Philly’s Hidden Past! This annual Pennsylvania Archaeology Month Celebration, now in its 7th year, is a day-long event co-sponsored by the Philadelphia Archaeological Forum and Independence National Historical Park. Hear archaeologists talk about the latest discoveries in our area! This year the event takes place on October 1st. It is hosted by the National Constitution Center.
3D Colonial Philadelphia Project — Digital Restoration of Thin-Shell Objects for Historical Archeological Research and Interpretation.
The PSAs drew upon Drexel-based research (NSF Grant #0803670) which combines new and existing methods in computer vision to partially automate the reconstructing ceramics from unearthed fragments. The research focuses on ceramic artifacts recovered from the site of the National Constitution Center on Independence Mall at Independence National Historical Park in Philadelphia, Pennsylvania.
Philadelphia Archaeological Forum The Philadelphia Archaeological Forum (PAF) is a non-profit 301-C organization dedicated to the protection and preservation of archaeological resources in the Philadelphia region. The organization raises awareness of archaeological heritage through educational programs and advises historians, architects, government officials, tourism concerns, and others about archaeological matters. PAF also facilitates communication among Philadelphia archaeologists and provides support for the publication of information relating to the archaeology of the city. Membership in PAF is open to all.
