Example of Term or Symbol



Die 1

The readingof the stamp is given a number


The precise die has an added letter

1a'/1a'' etc.

Modified dies (damaged, altered by recutting, worn or broken, or copied by surmoulage) have ' or " or ''', etc. added to the die letter for successive changes.

1─ a etc.

Reported    Reported readings of stamps which have not been seen are given as 1─ etc. with a plain reading or one containing irregular letters in identical or approximate form, as with BIVIICIT.

A– etc.

Means that only the first letter of a name is imputed.


  The source of reported readings is normally given: 

C = Corpus Inscriptionum Latinarum (a detailed            

reference is only given when the entry is not in the

expected place in C.


Diameter of the footring of a vessel.


Overall diameter of a vessel.


Means that we have recorded a stamp from an excavation and the following number is the excavator's code.


Abbreviation for "form"


Firing list: a list inscribed on a single samian vessel placed in the kiln with the rest of a load, giving the names of workmen involved and the types of vessels to be fired.


Overall height of a vessel.


Height of ''kick'' in the centre of the base of a dish.


Manuscript (names) in the moulds of decorated vessels


Pot(s) without number(s).


Unknown findspot


Oswald's Index


Signifies a MS addition to O's own copy of his Index or various MS lists which he had acquired, sometimes with rubbings included.


Denotes strap–handles along the rim of a vessel.


Plainware dies used to stamp moulds.

Variant forms



The use of the suffix R stems from Eric Birley's happy decision to label the rouletted dishes of f.18/31 from the Birdoswald Alley in this way (Birley 1930, p.184, 3). We have applied the suffix to the corresponding variants of other dishes, such as 15/17, 18, etc., all of which have a band (or, occasionally, bands) of rouletting on the base, usually coinciding with the position of the footring. Such dishes are normally larger than the basic types and are essentially different in form, as Ritterling appreciated. The angle between the base and wall is normally more obtuse (except for Walters 79R and Ludowici Tg, where the angle remains the same).

This is used for early varieties of the cup 24 with the footring bevelled, so that the ring rests on its outer edge.

27g etc.

This is used for the variant of 27 with the footring stepped or grooved on the outside. In South Gaul this is almost exclusively a pre- or early-Flavian form. A much slighter groove appears very occasionally on the footring at Les Martres-de-Veyre. Footrings grooved in this way occur, rarely, on other first–century cups, e.g. R.8, R.9.


Here the form has a rouletted upper wall, and often the elaborate internal and external mouldings at the constriction of the wall found on Loeschcke 11.


This is used for the normal South Gaulish variety of the cup, with external grooves at the top and bottom of a slightly convex wall, and an internal moulding at the junction of the base and the wall.


This is derived from 33a, but is taller in proportion to its diameter as well usually as being thick and poorly-made, with the base and wall virtually merging in a curve.


This is used for variants like 33b, but still with a hint of an external angle at the junction of base and wall.


See 15/17R. The rouletted version of 36 occurs only in East Gaul and is probably entirely third–century.

37 (etc.) mould

Used, e.g., where a signature or stamp is recorded from a mould for a decorated vessel

R.8 etc.

Ritterling (Hofheim) forms are given as R.8 etc., Curle's Newstead forms as Curle 11, Curle 21, Curle 23, and Ludowici's Rheinzabern letter series (Sa, Tb etc.) is also used when essential or helpful. Other common series are those of Walters and Bushe–Fox.


Means that someone has claimed to have identified a stamp from a previously published example. (Obviously there are slightly different levels of confidence with these.)


Indicates a stamp identified normally from a published drawing.


Indicates a reference to special dating, see Appendix (******)


Indicates an incomplete reading.


Indicates an uncertain reading.


Indicates the date–range of excavated material where the individual numbers of stamps have not been noted.


Indicates letters in a signature which are interrupted by decoration.


Indicates tentative attribution to a potter, die form or provenance. These will not be included in any statistics generated by the database.

Indicates probable attribution to a particular die. Such entries will not be included in the database.

Indicates less possible attribution to a particular die. Such entries will not be included in the database.


Indicates a reading incomplete at the beginning.


Indicates a reading incomplete at the end.
