Authentic Ishi Points from Private Collections. THE GOLD STONE POINTS
Rare Gold Stone Points Made By Ishi at Knapping Demo.Authentic Ishi Points from Private Collections. THE GOLD STONE POINTS
Through a shadowy maze of secret connections and back room meeting and a plethora of mass mailings fallowing up on leads and dead ends. Here is a portion of the Ishi points given away or sold by Ishi from his museum flintknapping demonstrations. All on this first post verified as authentic by chain of position and eye witness testimony and expert lithic technology diagnostics.
This first set is extremely rare, two points made by Ishi from MAN MADE Italian “Goldstone” , a copper powder laced glass made by Italian monks and imported to America.
Point one is a classic side notch point with uncharacteristic wide notching, gold stone is brittle and tends to brake away on delicate tear drop notching.
The second point appears to have ear snapped during notching and may have been picked up by the customer as a discard at the demo?
ABOUT ISHI POINTS
Today Ishi is well known for the arrowhead named after him, a
stylized side notch type, he commonly knapped at his museum home, In
this case, Ishi's short five-year stay at the Museum of
Anthropology, University of California, a legend born of an odessy
that began August the 9th, of August 1911 ending on Ishi's death
March 25, 1916. According to Nelson (1916) . Nothing gave Ishi, and
the visiting public, as much interest and satisfaction as his
arrowhead chipping. The Ishi Point type discussed, he made several
varieties, is as follows: The classic Ishi point is best known for
its symmetrical tear drop notches in the lower margin of the point.
The notch enters at less than a thirty-second on an inch at the
entry point then expand to an eighth of an inch wide or more in the
body of the point. The deep teardrop notches extend three eighths to
a quarter of an inch deep into the face of the basal region. This
gives the neck area, between the notches, a similar diameter of the
prospective arrow shaft creating the perfect haft.
The classic Ishi point has a blade edge that is either straight or
incurvate. The base is concave. The point has sharp angular ears
below the characteristic notches. The point has a triangular form
giving the point the overall delicate but deadly outline. The point
has diffuse diamond cross-section created by a medial ridge. Ishi
points have closed tear drop notches.
The medial section of the Ishi point has subtle oblique flaking
patterns, more pronounced on the elongated specimens. Oblique or
parallel flaking is done, according to Errett Callahan, to create an
extremely sharp edge, as oblique edges do not have delta flakes and
therefore less final retouch is necessary and the blade edge is
razor sharp. The blade edge on an Ishi point is usually incurvate,
this a result of the final pass of oblique medial flakes. The clear
glass material gives the point an ice crystal look, that combined
with its' oblique parallel pattern flakes and near perfect symmetry,
transcends all description of beauty.
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Goldstone is a type of glass made with copper or copper salts in the presence of a reducing flame. Under normal oxidative conditions, copper ions meld into the silica to produce transparent bluish-green glass; when the reduced goldstone melt cools, the copper remains in atomic isolation and precipitates into small crystalline clusters. The finished product can take a smooth polish and be carved into beads, figurines, or other artifacts suitable for semiprecious stone, and in fact goldstone is often mistaken or misrepresented as a natural material.
The most common form of goldstone gives the illusion of being reddish-brown, although in fact that color comes from the copper crystals and the glass itself is colorless. Some goldstone variants have an intensely-colored glass matrix—usually blue or violet, more rarely green—and a more silvery appearance to the suspended crystals, whose color may be partially masked by the glass or which may be based on different metals than copper (perhaps cobalt, manganese, or chromium).
The manufacturing process for goldstone was discovered in seventeenth-century Venice by the Miotti family, which was granted an exclusive license by the Doge. Persistent folklore attributes the discovery and secret of goldstone to an unnamed Italian monastic order, giving rise to the alternate name "monk's gold" or "monkstone". Another name, "stellaria", is based on the starry internal reflections.
Curiously, goldstone is one of the few cases where a synthetic simulant provided the eponym for the similar natural stone. The original Italian name for goldstone is "avventurina" or some similar word or phrase indicating its accidental discovery, hence the mineral name "aventurine" for forms of feldspar or quartz with mica inclusions that give a similar glittering appearance. Yet another name for goldstone is "aventurine glass", but this should be discouraged to avoid confusion with the minerals."
Most of you have heard the story of Ishi a thousand times, the tear
filled tale of the last natural American. Ishi wandered out of the
wilderness in 1911, starving. confused and mourning the loss of his
family and race. The last Yahi-Yana of Dear Creek, California.
Rescued and given sanctuary in the Museum at University at California
Berkley where he lived doing odd jobs and demonstrations until his
death by TB in 1916. Ishi was said to be a reserved and intelligent
gentleman, and an excellent flintknapper. Ishi's friend Dr. Saxton
Pope wrote this of Ishi when he died; "He closes a chapter in
history. He looked upon us as sophisticated children, smart, but not
wise....He knew nature which is always true. His were the ualities of
character that last forever. He was kind; he had courage and self-
restraint, and though all had been taken from him, there was not
bitterness in his heart. His soul was that of a child, his mind that
of a philosopher."
Of late, Ishi has been in the news quite a bit, Researcher Steve
Shakely, of Kroeber Hall at Berkley, states that Ishi may not have
been a Yana after all but, based on physical and anatomical
measurements of Ishi himself and the point type he made, he may have
been a Wintu, a neighboring tribe. Furthermore in the news, the
California Indians have been trying to get the existing remains of
Ishi back from the Smithsonian for burial. Originally Ishi wanted to
be buried in the traditional Yahi-Yana fashion, but the powers that
be at the time had dismembered and burned his body. Before they
burned his body they cut out his brain and sent it to the
Smithsonian. In recent news releases it appears that Ishi's remains
may be returned to his Dear Creek home for burial. The delay in
returning the remains had to do with the fact the Ishi had no living
relatives, recent DNA testing has resolved the issue. In addition,
another bit of Ishi news came about when researcher, Dennis
Torresdale discovered a small cash of authentic Ishi points in Ishi's
waste flake collection in an old coffee can in the basement of the
museum at Berkley. Dennis was extremely noble and turned the points
in to the museum, according to Ishi collector, the late Charlie Shewey, the
last authentic Ishi point sold at auction for a cool $27,000.00.Subsequent
research indicates some have been on the black market for much less.
MY ISHI RESERCH PROPOSAL (BASED ON Rondeau, M.F., and V.L. Rondeau. RESEARCH FORMAT)
RESEARCH PROPOSAL: ISHI LITHICS AND GLASS DEBITAGE
ANALYSIS; A WINDOW TO PROTOTLITHIC UNDERSTANDING,
A LITHIC TAXONOMY.
RAY H. HARWOOD
A. Statement of the Problem There has been a wealth of books and articles related to Ishi and his projectile point knapping. Ishi’s biface production trajectory and physical approach is used throughout experimental archaeology and “folk-knapping’ today (Shackley 2001) and can be traced directlyback to Ishi via Crabtree. However, little has been done thus far on an extensive debitage study, especially a systematic replication of his lithic works relating to the studies of said debitage. According to Shackley(2001) though the objects Ishi made are nearly deified in some circles, an examination of his lithic technology, with current advances, has simply not occurred, possibly as a result of the rather romantic effect of this historical figure.
Succinctly stated; the problem to be researched is the application of modern lithic
debitage analysis to the existing Ishi glass and lithic refuse. Debitage, defined as "residual lithic material resulting from tool manufacture. Useful to determine techniques, and for showing technological traits" (Crabtree 1972:58). The anomaly of glass and lithic reduction in the proto-historic era (protolithics), also known as contact or historic period lithic analysis, will be used to extract important data for this little known, and seldom studied, subfield of lithic technology. I use the term “lithic anomaly” here to designate an artifact class possessing a unique set of definable salient attributes such as might indicate distinct manufacturing and/or techno-functional behavior.It is the focus of this proposed research endeavor to increase the flaked glass and protolithic database with use of modern micro-lithics study methods for debitage classification and subsequent anayasis and and replicative verification through extensive flintknapping experimentation . Replicative studies will focus on the attribute and statistical analysis of the debitage created while maintaining close attention to precise, systematic and historically accurate replication. The lithic debitage will be processed into a precise taxonomy. Taxonomy (from Greek taxis meaning arrangement or division and nomos meaning law) is the science of classification according to a pre-determined system, with the resulting catalog used to provide a conceptual framework for discussion, analysis, or information retrieval. In theory, the development of a good taxonomy takes into account the importance of separating elements of a group (taxon) into subgroups (taxa) that are mutually exclusive, unambiguous, and taken together, include all possibilities. In practice, a good taxonomy should be simple, easy to remember, and easy to use. Flintknapping experimentation is one means of expanding the theoretical scope and application of lithic debitage studies. Flintknapping experiments, replicative systems analysis, have shown, when properly applied, to be a most reliable method, indicating the prehistoric agents responsible for the redundant and unambiguous patterns that occur in the prehistoric flaked stone record (Callahan 1979; Crabtree 1972, 1973; Flenniken 1980; Muto 1971). These identified attribute patterns have been found to vary according to the techniques of production and the stages of reduction, thus exposing clues to technique and methodology (Breschini and Haversat 1991). There is even an indication that the pressure technique used on the long glass points, Ishi made at the museum, was somewhat different than on the smaller obsidian points (Harwood 2001; Shackley 2001). According to Shackley (2001)
“there is no evidence on the performs at the Hearst Museum or in the literature
That Ishi abraded the margins during reduction, even when using obsidian and glass, but to produce the oblique parallel effect he was so proficientat doing, he must have prepared the platforms.” These theories can be tested through micro analysis of the debitage.
In spite of some support for this analytical technique (Patterson 1983), a number of potential problems with size class analysis, as well as, debitage replication have been recognized. These include: 1) different techniques to manufacture similar items; 2) the mixing of waste flakes from different flaking techniques; 3) failure of flintknapping to accurate replicate a collection under study; 4) variations in debitage due to raw material differences; and 5) the collection both prehistorically and historically of certain debitage specimens (Stahle and Dunn 1983:94).
B. Nature and Design of the Project
Described herein are the details of what the project intends to do and where the project will be carried out. The bulk of the research will be carried out at my home and will involve the systematic replication of 10 sets of 10 projectile points each and the subsequent debitage classified and categorized. Comparisons will be made with the actual degitage of Ishi and theories regarding the original; lithic reduction sequences speculated’
The raw materials and technical attributes in the Ishi debitage collection would be subjected to classification and close attribute studies. Various methods of flintknapping replication would correspond to ascertain the type and origin of the various debitage manifestations. From here statistical inferences and theories will be considered, correlations made and the final data used to infer viable reduction and notching scenarios.
The project would be carried out in several phases:
1. A close review and study of the existing publications relative to this study.
2. Initial inspection at the museum and the Ishi artifacts on display.
3. Interviewing key personnel in the lithic and Ishi research community.
4. A close inspection and study of the Ishi debitage, and possibly his tools and stone artifacts.
5. Extensive flintknapping replicate studies and creation of the Ishi lithics taxonomy reference collection; points, performs and debitage .
6. A follow up inspection of all debitage, both Ishi’s and that from the replication
Phase of the study.
7. Final conclusions, peer considerations, and outcome of research project published. Preliminary reports on the finding of this research project will be submitted to:
SCA Newsletter and SCA meetings paper presentation (2008), Journal of Lithic Technology,
This section should describe the procedures and techniques for carrying out the project and should include at least the following points:
the nature of the data/information to be collected, studies will focus on the attribute and statistical analysis of the Ishi debitage to identify lithic reduction sytems used by Ishi.
1) the methods for collecting the data: Separate the debitage into categories based on raw material, then subclassify by attribute. Replicate material with flintknpping experimentation and create taxonomy.
2) the sources of information such as library materials and field notes (with descriptions of field methods where appropriate) will be provided.
D. Resources and Clearances
1) sources of funding (personal funds, and possible future grants),
2) facilities available (such as computer use and lab/office space in the field and at the home institution), CSUB Archaeology lab for analysis of replicated lithic debitage and corresponding projectile point reduction sequence studies, taxonomy and close analysis and classification of same. UCB Pheabe Hearst Museum for study of historic Ishi lithics. Personal residence for systematic flintknapping replication of 100 test units (“Ishi Points”) and debitage retrieval.
3) equipment available, if applicable; approximate replica of Ishi’s knapping kit will be prepared by student. Diagnostic and analysis tools for magnification and other micro-lithic evaluation are house at CSUB (for replicated protolithics) and UCB (for Ishi’s historical protolithics).
4) assistance available (e.g., contacts in the field or consultants to the project); Several contacts have been established at both the PhD level and that of experts in the field of “folk knapping”, also primitive archery experts have been consulted for their perspective of technological form and attributes of this projectile point style.
5) preparedness to conduct the research (e.g., background course work, prior related research experience, personal knowledge of the study site in terms of language and culture); The research student has familiarized himself with the back ground literature on both Ishi and the field of lithic studies. The research student has been flintknapping, as an amateur, off and on for 30 years and has learned to replicate all of the Ishi styles of projectile point. The research student has familiarized himself with castings of Ishi styles of projectile point procured from “Lithic Casting Lab”.
6) documents obtained or to be obtained (including Human Subjects and Informed Consent Forms, clearances from contact persons, letters of introduction from research director and from host institution, passport/visas, etc.). Letters of personal introduction provided were those used for my Graduate school application package.
E. Time Table
Specify the projected start up date, the period of fieldwork (broken down by time needed to set up and initiate the project, the time engaged in data collection, and the time required for data analysis and write up of the results), and a projected date of completion for the entire project. The initial inspection of the Ishi’s protolithic debiatge at USB Pheabe Hearst Museum will be the starting point. The replication, categorization and report completed and written by SCA meeting of 2008 in Burbank, California.
In order to understand these stone and glass artifacts, and the person whom made and used them, archaeologists must understand the processes involved in the acquisition of the raw material, production strategies and stages of lithic reduction, and the function, and final disposition of these lithic artifacts. In the past years, experimental studies involving the manufacturing and use of stone tools have been integrated with studies of refitted or conjoined lithic artifacts and microwear analysis. The result is a much more dynamic view of the variability in assemblages of lithic artifacts. Continuing these research techniques into the Ishi lithics and subsequent debitage is a logical progression. COMMENT: It can be expected that a satisfactory fulfillment of items A through D, as well as G, will be directly applicable toward completing the final write up of the project.
