Details of the ceramics are stored in a data set which has 9
variables. These variables contain the data recorded for each
entity. The basic entity in this dataset is a single sherd of
pottery or group of sherds with the same values for all
variables. This does not necessarily imply that all the sherds
originated from a single vessel, only that the sherds are
indistinguishable from one another using the variables which are
presented here. This dataset has been developed from the data
that were originally recorded during the cataloguing of the
pottery. The original data have been tidied and consolidated to
reduce near duplicate entries in the original dataset, for
example original separate records for two body sherds of the same
fabric have been consolidated into one record here. The values
used have been standardised from the original field recordings
and translated into English. The pottery was originally described
with reference to a set of working illustrations which was
created as cataloguing progressed. Subsequent study has reduced
the number of illustrations by amalgamating similar illustrations
into a single type for publication purposes and also by making
reference to similar pottery published elsewhere. This process
has also consolidated the records.
For the purposes of this publication the data structure used
is a flat file dataset with 9 fields which are described below.
WARE: variable to provide a series of broad
classifications for the pottery: values are either in
common use or developed for this dataset. Some examples
are ´Bucchero´ ´Fine Creamware´ ´Coarseware 1´.
FORM: variable to describe the general shape of the
vessel: values are in common use, for example ´Jar´,
´Bowl´, ´Amphorae´ etc.
TYPE: variable to record the detailed variations in the
shape of each FORM of vessel: values are often 1, 2, 3,
etc. to enable a description of the sherd as WARE x, FORM
y, TYPE n. However, additional complications are required
to differentiate parts of vessels. If an integer occurs
alone this indicates a type of rim sherd, otherwise the
nature of the sherd is indicated, for example Handle 1,
Handle 2, etc. or Base 1, Base 2, etc. These values have
been specifically developed for this dataset. They are
directly equivalent to the TYPEs published from the city
at Doganella and the Farm at Podere Tartuchino (Perkins
and Walker 1990;
Attolini and Perkins 1992).
TYPEs with the same number but in different WAREs are
similar to one another, so Coarseware 1 Jar Type 1 is
similar to Coarseware 2 Jar Type 1. For the amphora made
at Doganella the TYPE refers to the divisions made in
Perkins and Walker 1990 so
the TYPE becomes DOG2A, DOG2B etc. As always there is an
irreducible minimum of sherds which do not fit easily
into a schema. These have been listed as miscellaneous
e.g. MISC1 etc.
FABRIC: variable to record the fabric of the sherd;
values are generally coincident with the variable WARE
but in some cases a ware has been subdivided into
NUMBER: variable integer indicating the number of sherds
in the entity.
DIAMETER: variable integer giving the diameter of a rim
or base sherd in millimetres. Precision is to the nearest
10mm unless the sherd presented a complete diameter when
it was measured to the nearest mm.
COMMENT: variable to record observed values which did not
easily fit into any other variable.
FIGURE: variable providing a reference to a line drawing.
SITE: variable to record the find spot of the entity. The
primary item recorded by the system is a topographical
location where archaeological material was found
identified by an abbreviated reference to a 1:25,000
Instituto Geografico Militare map sheet by a code of two
or three letters: e.g. SD = San Donato, MAG = Magliano in
Toscana followed by an integer e.g. SD23. The integer has
no significance beyond being a unique identifier for the
location, although in many areas the numerical sequence
is coincident with the order in which the archaeological
sites were identified. If required the location number
was sub-divided into units to represent different spatial
locations of surface scatters within the topographic
location or chronological divisions discovered in the
material. These sub-divisions are represented as
pseudo-decimals e.g. SD23.2. A location with only a
single scatter or a single chronological period present
is always presented as e.g. SD23.0
