A major goal of the 2013 study season was to begin an environmental analysis of the synagogue. Environmental archaeologist Robyn Veal, an expert in the analysis of ancient charcoal, has joined the team as our environmental advisor. Last week she came to the lab to oversee the construction of our first flotation tank, which allows us to extract tiny seeds, bones and other small finds from soil samples taken during the synagogue excavations. Charlene Murphy, who specializes in the recovery, analysis, and categorization of ancient microfloral remains, oversaw the flotation of our soil samples and performed the preliminary processing of the recovered materials.

We floated samples from several different excavation contexts, including the soil from a drain, several samples from the sand fill underlying the synagogue complex, and soil from a large fill discovered to the east of the complex. Dr Veal and Dr Murphy were very patient and effective instructors!

On the following day, Dr Veal set up her microscope to examine some small pieces of glass and fish bones recovered during flotation. She also provided a digital microscope, which allowed us to view the finds on a computer screen and photograph them. The demonstration drew quite a crowd–every member of our study season team came over to the computer to see the finds, and a couple of men from Ostia’s road-building crew stopped by for a quick science lesson! We look forward to collaborating with Dr. Murphy and Dr. Veal in the future!

Our excavations have continued to be interesting and productive, despite the heat wave that has held Italy in its clenches—dubbed “Scipione” by Italian meteorologists, as the wind blows up from Africa. Our team has been grateful for the nearby shade trees which we sit under during paperwork and for breaks, and we have been careful to keep our water cooler full.
Several team members have completed the painstaking task of uncovering a mosaic by carefully peeling back the dirt without causing a single tessera to pop out of place. The mosaic a white field with black bands at the edge, and is not decorated in any other way. Some portions of it are missing, so we are eager to preserve what is left—we are applying for permission to have it lifted, restored and reset within the next year.
Kimberly Bauser and Mitch McDavid clean the mosaic with all-natural sponges and distilled water.
The team in charge of pulling back layer after layer of sidewalk pavement in the area between the Synagogue and the Via Severiana may have reached “pay dirt” this week when they uncovered a surface layer that seems to run under the Via Severiana, perhaps pre-dating the construction of that road.

In other areas of the Synagogue, we have been surprised to discover that one reticulate wall runs much deeper than we had expected, and have also found some features (steps? foundations?) that certainly pre-date the existing structure. In the next week’s excavations we hope to learn more about these earlier features and perhaps will be able to build a more complete vision of the earlier phases of the building.
I’m pleased to report that the OSMAP team is headed back to the field this summer under the direction of L. Michael White (UT-Austin) and will be excavating at the synagogue from the 20th of June to the 15th of July. More details on the senior staff and team members will follow.
Thanks to everyone who has expressed interest in the Ostia Synagogue Area Project (OSMAP), overseen by UT-Austin. Work has ended on the 2010 season and we will resume all posts in 2011 when we return to the field. Until then, it is our pleasure to announce that summaries of all the previous season are now a part of the on-line archaeological database: Fasti OnLine.

The Project Staff
As noted in our 2001 Preliminary Report, the Soprintendenza per i Beni Archeologici di Ostia (at the time) approved the first official numbering system which locates the synagogue structure at Ostia within its larger urban landscape.
In anticipation of two preliminary field reports which the OSMAP stuff has begun to prepare this spring, we are happy to make this plan available here on the blog, as well. The plan reflects the final phase of the building as it is known today (chronological dating of the phases will appear on a future top plan, after a final review of archaeological and architectural data).
