The Big Reveal: Archaeological Mystery Objects

Last week we posted three mystery objects excavated at El Presidio de Santa Bárbara State Historic Park, along with polls so you could guess the answers.   Below are the correct identifications of these objects.   How did you do?

Dried ink for calligraphy.  These small containers of dried ink can be wet with a brush, producing a black ink used for writing Japanese or Chinese characters. These objects were excavated from a trash pit associated with the early-twentieth-century occupation of the Presidio site by Japanese Americans.

 

Bale seal. Bales seals were in use throughout Europe going back to the medieval period to identify the content and quality of parcels, batches of textile, and bales of goods.  This bale seal was excavated from a trash pit associated with the comandante’s residence adjacent to the chapel site.

 

Dispenser for powdered Tabasco.  Marked with the company brand name on the bottom, this ceramic shaker shaped like a chili pepper was used to dispense a powdered form of the spicy condiment.  Tabasco brand products have been manufactured by the McIlhenny Company in Avery Island, Louisianna since 1868. Still in use in some areas of the Southern  United States, powdered Tabasco is not readily available on the market today, and this ceramic shaker is extremely rare.

Digitizing the Past: the Delfina de la Guerra Collection

By Katherine Lowe

When processing a new collection, one of the fun things is thinking about ways to share the collection.  Thanks to constantly evolving technology, there are so many new and interesting ways to share historical collections with a much wider audience. Researchers can now search and browse millions of photos and letters from the comfort of home. Here at the Presidio Research Center, we are working on digitizing a portion of items from Delfina de la Guerra’s personal papers. This important collection detailing a portion of Santa Barbara’s history will be available for viewing on the website. This blog series will give you a behind-the-scenes glimpse at this process.

There is no substitute for seeing a letter or photograph in person to get a true sense of the scope of its historical value, but digitization offers us a close approximation. One of the most rewarding aspects of processing and researching historical material is viewing it up close and noticing the details that make it truly unique, such as the way the ink on a letter has faded or how the nature of handwritten letters has evolved over time. Our goal with this digitization project is to translate that feeling into a digital setting.

After selecting a portion of the materials for the digitization project, the scanning stage is next. The most important thing is for us to get a clear image that is as close to the original as possible.

One of the advantages of digitization is the ability to zoom in for a closer view, so resolution of the scanned image is very important. For example, consider this photograph of an unidentified woman.

The following set shows what happens when you zoom in on a portion of this photograph that has a lower resolution (left) versus something that has been scanned with a higher resolution (right). The image on the left is more blurry, while the image on the right has more detail.

In the next blog post, we will discuss historical research as it relates to digitizing this collection.

Once You Dig It Up, What Happens to It?

By Tacy Kennedy

This is a great question, and after serving as 2011 Archaeology Field School Lab Director I can give you the answer!

I have had the good fortune to be a part of the Presidio Archaeological Field School for the past two years, first as a student and then this year as the Archaeology Lab Director. After my field school I volunteered at the Presidio and learned the system used for cataloging artifacts. This later led to the opportunity to serve as lab director this summer.

During the field school, students split their time between learning excavation techniques and processing finds in the lab. The first thing that the students do in the lab is sort the artifacts by size (> or < 1/2”) and by type.

The artifacts are then counted and weighed and those measurements are recorded on inventory sheets. Most of the items fall into general categories that have been previously observed by archaeologists at the Presidio. Common artifacts are roof and floor tiles, nails, bottle glass, and various types of pottery known to have been used at this site during both the Spanish period and during later occupation.

Once the sorting and recording of the artifacts has been completed, the artifacts are bagged and given to me, the lab director, along with the inventory sheets, to be entered into the official catalog on the computer. It is my job to look at each artifact or group of artifacts and evaluate whether the finds have been correctly identified. As this is a learning environment and many of the students have not come into contact with items commonly found in this area, particularly those students from other parts of the country or world, artifacts are occasionally mistakenly identified as something else. If I find that an item has been incorrectly identified, I fix the entry on the inventory sheet and notify the students of the mistake and explain to them what the item is so that they will recognize it in the future.

Once I decide that the artifacts have been correctly identified, I enter them into the catalog. Up to this point the artifacts have simply been categorized by type, but in the catalog each item is assigned a category (personal, military, etc.) and then within that category a general material type is chosen (masonry, ceramic, etc.). The material type is then further refined to specific material type (copper, plaster, etc) and finally the object itself is specifically identified (marble, bead, etc.). To further describe the artifact there are places to describe what portion of an artifact was found (whole, rim, etc.), the color of the artifact, and the count and weight that were recorded on the inventory sheets. Once all of the information for the artifact has been input into the computer, tags are printed and placed in the bags with the artifacts so that any future observers will know exactly what they are looking at and where it came from.

Thanks team, Presidio Pastimes: The Santa Barbara Presidio’s Asian American Neighborhood was a Hit!

On Saturday October 1, SBTHP hosted our second annual living history day featuring Santa Barbara’s Asian American traditions at El Presidio de Santa Bárbara State Historic Park. Over 500 visitors attended the event to watch performances of Taiko drumming, Hula, and Tai Chi, and try their hand at origami and Chinese brush calligraphy among many other activities.

We are grateful to our Asian American History Advisory Committee for their boundless enthusiasm and hard work in pulling off this ambitious event. SBTHP maintains many volunteer committees who assist with all of our projects and programs. We rely on these community members for the creativity, dedication to partnership, and sweat equity that help take our programs from good to great.  Thanks team—and we can’t wait to see what you come up with next!

Take a Seat in the Presidio Chapel!

Several years ago SBTHP board member Tim Aguilar showed us a Mission-period bench he had acquired. Tim noted that a few benches of the same design would be appropriate additions to the Presidio Chapel.    Although we know that most of the residents of the Presidio would have kneeled on floor mats during services, a few benches like Tim’s likely lined the walls during the early-nineteenth century.  A recent donation by Virginia Ridder made reproduction of Tim’s bench possible.   Thanks to the hard work of Tim and many interns, students, an experienced carpenter, and a talented blacksmith, we now have seven reproduction benches lining the walls of the Presidio chapel.   Want to view the world from the perspective of an early nineteenth-century Spanish resident of the Presidio?   Next time you visit, pop into the Chapel and take a seat!
