Constituent Inventory

Giorgio Buccellati – June 2010, July 2024

S2.1 Introductory

Within the two broad classes of constituents identified as elements and referents, we must now describe the specific minimal constituents that can be identified in the archaeological record. The applicable inventory is given in this chapter, with an explanation of the underlying concepts. The pertinent codes will be introduced in the next chapter).

In the presentation, I will further distinguish between two sets of terms.

The first set includes those elements and referents that can be so understood in a technical as well as a conceptual sense; They are also subject to labeling, in the sense that they are identified by specific alphabetic codes and are indexed numerically (see next chapter). As such, they are used as organizing principles in the archive. – For example, a feature or a stratum are indexed and labeled elements, represents respectively by the label "f" and "s". A complete list of labels is found below.
The terms of the second set, on the other hand, are only used discursively for descriptive lexical purposes, and thus receive no label. For example, the terms "zone" or "horizon" are unindexed and unlabeled elements.

It is important to note that only indexed constituents (those which receive a label) are properly part of the closed -emic system (for which see above): none can be added, nor can any be subtracted, without affecting the system as a whole. Purely lexical (non-indexed) constituents, on the other hand, are part of an open system: those mentioned here are only indicative, and as many can be introduced as is useful in any given context.

S2.2 Elements

S2.2.1 Stationary and mvable elements

There are two major types of elements, depending on whether they are stationary or movable. The distinction between the two does not rest on the physical impossibility or possibility, respectively, of moving what is found in the ground. The London bridge or the Assuan temples were moved, the pyramids could be moved, but they remain nevertheless stationary. The proper discrimination between the two types should rather be understood in the following terms.

A stationary element is one whose typological identity is tied to a place, whereas a movable element is one whose typological identity is independent of place. Thus a wall or a floor accumulation are such to the extent that they remain in place as originally found: a dismantled wall, a sifted floor accumulation are no longer a wall or a floor accumulation. By contrast, a jar or a chunk of wood remain such regardless of whether they are seen in their original context or not.

S2.2.2 Link to emplacement

Note that the link to a place is not meant in a geo- or topographical sense: the London bridge moved to Arizona or the Assuan temples raised to higher ground retain their typological identity as stationary element (whatever else may have been lost in the process, see presently). Rather, the link to a place is meant in the generic sense of emplacement (see above, 2.2; 4.2 missing sections, ZGx13 mDP): it is not only the permanent correlation of bricks and mortar that make up the wall, but also its permanent correlation to other walls, floors, etc., that gives it its proper identity as a wall. (In this sense, topography and geography are higher nodes which give further meaning to the wider assemblages of walls and floors – and this is what is lost in the case of the two examples mentioned above. But the stationary integrity of the elements can be reconstituted at the lower nodes of a given structural entity – a bridge, a building.).

The distinction between stationary and movable elements is thus essentially stratigraphic, since reference to typology is closely related to emplacement. I prefer to retain such a minimalist distinction, rather than introducing more differentiated definitions, for two reasons:

first, the more generic the definition the less problematic is a decision in the field at the moment of excavation; there is ample space for greater specificity within the sphere of lexical definition that can be added at any time during subsequent analysis;
second, it is preferable to remain as close as possible to stratigraphy as distinct from typology in the primary labeling, since the former is the primary goal of the excavation process as such. For this reason, I do not distinguish further the stationary elements into such categories as installations and deposits (see Schiffer; Miller-Rosen; Pfälzner ADD LINKS, ZGx13 mDP).

S2.2.3 Features and items

The term used for any stationary element is feature. Under this term are subsumed, therefore, such diverse entities as a wall or a pit, a floor surface or a floor accumulation.

The term used for any movable element is item. Under this term are subsumed, therefore such diverse entities as a cuneiform tablet or a jar, a carbon sample or a stone specimen.

Items are subdivided in two categories, depending on the method used for their volumetric localization. An item proper is triangulated individually (see below 16 missing section, ZGx13 mDP), while a q-lot (for quantity lot) is a quantity of movable items (further specifiable as components), triangulated as a volume.

A q-lot has the following characteristics: it is defined (1) as a locus (see presently) and (2) as a level (intersecting the locus; see presently for the notion of level); also, (3) it is valid for only one day of operation.

S2.2.4 Items and q-lots

It is important to stress that items proper and q-lots are distinguished purely in terms of volumetric specification (see presently for the relationship of q-lots to aggregates). As indicated, an item is triangulated individually, whereas items in a q-lot (q-items) are triangulated with reference to a larger volume.

A q-lot may thus be conceived as a parallelepipedon (more simply, a box) containing a variety of items which are triangulated not individually, but by reference to the larger “box.” It appears, then, that a q-lot must be further distinguished to refer to individual items within it.

Accordingly, the items within a q-lot are differentiated into three categories, which reflect the relative frequency of what can be found within a q-lot: pottery; bones; anything else (objects, specimens or samples).

S2.2.5 Overview

To summarize, movable items fall into the following groups:

item proper (triangulated individually)
items within q-lot, triangulated within a "box" and distinguished as:

pottery = q-pottery = qp
bones = q-bone = qb
any other items = q-item

The following lexical definitions of elements will also be useful for an understanding of the concept of item.

An object is a manufactured item.
A specimen is a non-manufactured item, subject to count (e.g. a single stone), whereas
a sample is a non-manufactured item, non subject to count (e.g. soil).

One should not confuse, therefore, “item” with “object,” “specimen” or “sample,” since “item” is primarily a stratigraphic concept, while the others are exclusively typological terms. In other words, an item can be an object, a specimen or a sample.

S2.3: Para-elements

S2.3.1 Composite

A composite is a normalized rendering of an item of which multiple exemplars exist. This definition could be applied to a variety of situations, e.g., the extrapolation of surface lines in drawing a vessel or wall surface, is a normalized rendering. However, the term is restricted to only such situations defined as pertaining to “items for which multiple exemplars exist”; the term itself, “composite,” refers to such multiplicity rather than to the normalization which occurs. A composite is assumed as a concrete single element, not as an idealized category. Examples are a composite brick (rendered from fragments) or a seal impression (rendered from a multiplicity of individual rollings).

S2.3.2 Imprint, negative, trace

An imprint is the mirror image left by an element on another element, such as the void left in the ground by the tone foundations of a wall that have been removed or the marks that a cloth has left on wet clay.

A negative is a missing item, and a trace is a missing feature, present as void and documented by the physical imprint it has left of part at least of its surface(s) on other element(s). Examples of negatives are objects on which sealings were placed, seals from which rollings were rolled, shovel marks; examples of traces are quarried walls that have left a void filled with later detritus. The two terms “negative” and “trace” are used so as to have the benefit of different labels for items and features, respectively; they otherwise refer to the exact same concept. Either term refers to the mirror image of the original element (e. g., the impression of a basket on the back of a clay sealing): in this sense the negative or trace is the interface between the original element and the void which has taken its place. However, the terms “negative” and “trace” refer not to this mirror image in a photographic sense, but rather to an element that is documented but not currently existent (thus a seal documented by a seal impression).

The following lexical definitions may help explain further the concept. A mold is the physical embodiment of the outer face of the void (e. g., the envelope around a cuneiform tablet).

A cast filling the void would give an accurate representation of the missing element reprewsented by the mold (and would be a positive in a photographic sense).

S2.3.3 Overview

To sum up:

negative/trace	original element, present only as void
imprint	interface left by negative/trace, now outer face of void
mold	physical embodiment of imprint, or physical envelope of interface (interface as seen from outside)
cast	filling of void contained by interface, or copy of original negative/trace (interface as seen from inside)

S2.3.4 Zero

Zero is a missing feature, which is inferentially probable but has left no physical trace. The term “zero” is used to stress the fact that no direct physical evidence is left of the element. Only zero elements which are essential for discussion will be postulated (for instance, a totally eroded fourth wall of a room), since there is otherwise no end to the number of zero elements that could be posited (e.g. door lintels, windows, etc.).

S2.4: Complex elements (element clusters)

An aggregate is a cluster of elements, defined on the basis of depositional analysis, e.g., items on a floor. It is to be distinguished from an assemblage, which is a cluster of elements, defined on the basis of typological analysis, e.g., walls, spouted jars. An assemblage is considered a referent, since it is not found as such; see presently 3.6 (3).

A join is the combination of two or more items which are stratigraphically distinct (because they have been found in distinct emplacements), but fit together and thus can be shown to be components of the same item, e. g., a tablet consisting of three fragments found in different emplacements. Each of the discrete stratigraphic items (e. g., the three fragments of a tablet) retains its original designation (and labeling) as an individual item.

Note that a q-lot is a complex element as well, in a very specific sense: it comprises a variety of typologically distinct movable items. If I consider it, however, an element (see above, 3.2), it is because of the considerations about nesting for which see above (chapter 2.4). Accordingly, a q-lot receives a single element label, and is further subdivided into components, while the individual entities within an aggregate are given individual labels as elements, and are subsequently subsumed under the distinct label of the aggregate.

S2.5: Referents

S2.5.1: Volumetric localization or positioning of elements

NOTE. This is an area where a radical change has occurred vis-à-vis the first edition of the Grammar (TGR-1 give link), as a result of the wide availability of GPS instruments. It is still useful to retain a distinction betwee points set by a professinal surveyor and points set by others. The term relay, that refers to the latter, is semnatically inappropriate (it refers to the physical act of drawing measuring tapes from contorl points), but is retained nevertheless.

A marker or benchmark is set by a surveyor and may be considered to have first order precision, while a relay is set by the excavator, and, however precise, may remain questionable as to accuracy.

A projected relay is one that does not exist as a physical point in the ground, but is assumed for specific triangulation purposes.

Two other lexical terms belong here. A section is a physical plane cut vertically through the deposition. A profile is the analytical rendering of a section (an index to spatial relationships of elements contained in the volume through which the section is cut).

S2.5.2: Analogical representation of elements

A photograph is an analogical representation by means of a camera. As such, it abstracts from its physical embodiment, i.e., it can be on film or digital, color or black-and-white, positive or negative, etc.

A drawing is an analogical representation of measurements for a given constituent or cluster of constituents, by means of hand drafting. As with a photograph, the concept of drawing abstracts from its physical embodiment, and thus it subsumes hand drawings, digital drawings, and scans of hand drawings.

A view is a window on a constituent or a cluster of constituents (e.g., a wall, a tablet in situ, a structure, a marker), giving an analogical representation by means of either photography or drawing. Two types of view are to be distinguished:

a photographic view (v)
a drawn view (w)

In practice, every view is embodied in one or more photographs or drawings; in a parallel way, the terms “photograph” and “drawing” refer to the physical embodiment of the view. However, since a view abstracts from the photograph or the drawing as such, the concept of view includes photographs produced with standard cameras, digital photographs, and scans of standard photographs on the one hand, and, on the other, sketches, line drawings, perspective or 3-D drawings. The main view is a single view in a web (see presently, 3.6 (2)), onto which secondary views are mapped as part of that view’s template (see presently, 3.6 (2)). A secondary view is a view within a web, for which no independent template is given, and which is instead mapped onto the template of the corresponding main view.

Figure 3-1a – Main view A16v3. The template of the main view includes web that refers to secondary views (here, only one is included, v3a). Items and features are identified, and boundaries are highlighted.

Figure 3-1b – Secondary view A16v3a. The secondary view v3a (taken as a direct low overhead).

Given a fully three-dimensional record, the application of the concepts of view and of web will be altered, but the basic underlying notion will remain the same. A view is the crystallization of a moment of understanding with the superimposition of labels that serve as an index to the analytical breakdown of the stratigraphic reality. Thus a thorough implementation of a GIS system will in effect serve as a maximal view, with direct hyperlinks to the same set of analytical details for which a grammatical definition like the one I am proposing here will continue to serve as an essential infrastructure.

A sketch is the same as a drawing, but for temporary use only. Since it is not a permanent part of the archive, and it does not qualify for electronic storage, it is not labeled as referent. If, for whatever reason, a sketch needs to be integrated in the archive, then it is considered a drawing.

S2.6: Complex referents (referent clusters)

S2.6.1: Volumetric localization or positioning of elements

A locus is a volumetric unit with minimal horizontal axis and unlimited vertical axis. Its converse is the level, a volumetric unit with minimal vertical axis and unlimited horizontal axis. Since we rely fully on absolute coordinates (and thus absolute elevations) for individual elements, and since the concept of stratum is used to refer to temporal sorting (see presently), a level is not used as an indexed referent.

A sector is a subdivision of an area or book. It is generally introduced for operational reasons, but indexed labeling remains at the level of the area/book. This may happen, for instance, when two distinct operations are conducted simultaneously within the same area, but cannot easily be recorded on the same physical book, e.g., because of a great difference in elevation or the presence of high baulks between the two sectors.

A square is a cluster of loci, with medium horizontal axis. In recent years at tell Mozan, we have begun to distinguish squares and loci with reference to the numeric sequence: we reserve the sequence from 1 to 99 for squares, and the sequence 100 to 999 for normal loci.

A quadrant is a partition of a square, introduced for operational reasons to be specified individually. In order to be assigned a distinct label, a quadrant must be defined as a locus.

An operation is a generic term for a unit or an area, a square, or a sector.

A zone is a topographical portion of the site, without precise boundaries, and loosely identifiable for some recognizable traits, such as the nature of the contours or the presence of some distinctive feature (see below, Fig. 14-… missing figure, ZGx13mDP, for a list of labels used at Tell Mozan.) It is indexed numerically for units, and alphabetically for areas.

A unit is a portion of a zone defined logistically for operational reasons and indexed numerically (e.g., A1). It serves as the basic sorting criterion for all field numbers assigned during the excavation. Given my understanding of the grid as a volumetric, rather than a physical, entity, units can be, and generally are, wholly asymmetrical, see below, 26… missing section, ZGx13 mDP.

An area is a portion of a zone, defined typologically as a result of architectural and functional analysis. It is indexed alphabetically (e.g., AK).

A book is the component of the archive which corresponds to a unit or an area.

Following is an example of how the terms apply to a specific case at Tell Mozan (see below, Figs. 14.3-5 missing figures, ZGx13 mDP for a site plan that identifies on the ground some of the labels):

A	a zone identified as a distinctive hill top
A6	a unit and corresponding book identified logistically (sectors may be used, without a separate label, e.g., to distinguish an upper and a lower operation within the same unit
AK	an area and corresponding book identified typologically (thus AK is the service wing of the Royal Palace)
A6k1	a locus of a predefined size, i.e., a square; it is indexed with a single or double digit number
A6k100	a locus within the unit/book; it is indexed with a triple digit number (without any particular relationship, in terms of labeling, to any square)

S2.6.2: Analogical Representations of Elements

Digital is the term used for a file that provides a cluster of relays, sorted typologically, and given in numerical form. For example, such a file may contain the relays that define a wall; they are entered in a certain format (see below, … missing, ZGx13 mDP), which produces a script file, used in turn by such programs as AutoCAD to provide a graphic rendering of the wall.

A plot is a cluster of digital files, reproduced graphically on screen or paper.

A template is a graphic overlay on a view, identifying elements and referents, including especially secondary views; it can be drawn physically on a print or a drawing, or entered as layer on a digital photograph or drawing; see below, … missing, ZGx13 mDP). A template might be conceived as a primitive application of a GIS concept, applicable as long as the implementation of a GIS system remains technically and financially out of reach for an archaeological project.

A web is a cluster of views, taken at the same time and pertaining to the same cluster of constituents, each view being taken from a different angle; all views are interlaced together on the same template.

S2.6.3: Typological and/or Chronological Sorting of Elements

An assemblage is a cluster of elements, defined on the basis of typological analysis, e.g., walls or spouted jars. (See above, 3.4, for a definition of aggregate.) An assemblage may also be used to refer to elements of an aggregate that are presented not as found in the ground, but according to their typological specificity, e.g., the organized arrangement of the objects found in a burial.

A horizon is a maximal unit of reference relating spatial elements in terms of temporal sequence. It includes all possible integrative considerations, especially regional comparative evidence, absolute date determinations, and textual references.

A stage is a segment within a particular sequence of strata and phases, which (unlike a horizon) does not retain its distinctiveness beyond the boundaries of the specific sequence.

A phase is an intermediate unit of reference relating spatial elements in terms of temporal sequence. It relies on broad structural and functional considerations. Phase distinction reflects substantial re-organization of space (e.g., abandonment of a building and rebuilding using a different footprint) and uses typological evidence (e.g., distinction in ceramic inventory).

A stratum is a minimal unit of reference relating spatial elements in terms of a temporal sequence. Strata are defined exclusively on the basis of stratigraphic criteria, especially types of contacts, e.g., floor and accumulation sequences in contiguous rooms, or pits cut from the same floor.
