The wines of Laietania

The wines of Laietania constitute one of the best-documented commodity groups in the Piridi database, with a corpus of 31 objects attested exclusively through tituli picti — painted inscriptions on trade amphorae. This corpus emerges from the intersection of two complementary filter paths: the typology path, which identifies containers of Laietanian amphora classes regardless of their inscriptional content, and the product path, which captures objects bearing inscriptions that explicitly name a commodity. That all 31 objects satisfy both conditions simultaneously places them at the core of the epigraphically attested Laietanian wine trade, representing containers for which typological identification and explicit product labelling concur.

Four product denominations survive in the inscriptions. Vinum is the most frequently attested (21 objects), appearing in original titulurae applied at the moment of packaging; its use without a regional qualifier indicates generic wine with no recorded appellation of origin — the commodity is identified but its specific provenance is not named in the inscription. The regionally specific denomination vinum Lauronense (10 objects) identifies the variety produced in the territory of the Laietani, centred on the Vallès Oriental plain of modern Catalonia, in the area of ancient Laurona whose name is preserved in the modern toponym Llerona, near Granollers north of Barcelona. A third denomination, vinum amineum Lic(---) (1 object), implies a named grape variety — the amineum vine being well attested in ancient agronomy as a prestige type — combined with a partially preserved gentilicium. Many of the formal tituli picti in this corpus also include numerals recording the years of ageing at the time of packaging, a standard quality marker in the Roman amphora trade, with four-year-old wine (vinum quadrimum) among the most commonly attested conventions. Strikingly, acetum — vinegar, a derivative of wine — is attested on a single object exclusively in a non-primary inscription, meaning it was recorded at a later stage of the container's commercial life after the original labelling; this implies either re-use of the amphora for a secondary product or a relabelling during redistribution, and cautions against reading every product denomination as evidence for the container's original contents.

The Laietanian amphora sequence follows a well-defined evolutionary order tied to the Julio-Claudian dynasty. The Pascual 1 Laietana, characteristic of the Augustan period, gives way chronologically to the Dressel 3 Laietana (12 objects), and then to the Dressel 2 Laietana (27 objects), the dominant form through the end of the Julio-Claudian dynasty and the most abundantly attested type in this corpus. The dominance of the Dressel 2 Laietana marks the peak of this commercial success — the moment at which Laietanian wine reached its widest Mediterranean distribution. The wine of Lauro praised by Pliny the Elder for its excellent quality among the wines of Hispania (Naturalis Historia XIV, 71) is primarily documented in this amphora type, a correspondence that anchors the archaeological record in the ancient literary tradition. Other vessel forms present in the data are typological synonyms — transitional or equivalent variants — rather than independent canonical types, and do not alter the essential picture.

Twelve individuals are documented through the tituli picti. Eleven appear in primary inscriptions and are to be identified as the principal commercial agents of the original trade — most plausibly negotiatores or mercatores active at the Laietanian production site. A notable cluster shares the Iulii gentilicium: Caius Iulius Tertius (2 objects), Caius Iulius Vitalis, Caius Iulius R[---], and Caius Iulius Fala[dus]?, suggesting a family network or collegial association at the origin of the commerce. Where stamps (sigilla) co-occur with primary tituli picti on the same containers, the combined evidence offers additional precision for identifying the production site and packaging context, since stamps typically attest the manufacturer or workshop while the painted inscription records the commercial transaction. Iulia Alcis stands apart: attested on two objects but exclusively in non-primary inscriptions, she belongs to a later stage of the containers' commercial life — redistribution, secondary ownership, or re-exportation — and should not be conflated with the agents of the original Laietanian packaging operation. The remaining agents — Lucius P(---) G(---) (2 objects), [-] Valerius Ruber, Marcus P(---) F(---), Lucius A(---) Y(---), Lucius C(---) H(---), Lucius I(---) L(---), and Caius L(---) L(--) — are identified only through abbreviated names, a common feature of tituli picti where brevity and legibility outweighed full nomenclature.

The findspot distribution reveals the Mediterranean reach of Laietanian wine commerce. Tunisia — specifically Carthage (Délégation de Carthage, 12 objects) — accounts for the single largest concentration, consistent with the city's well-attested role as a redistribution node in the Roman western Mediterranean. France contributes 9 objects, the majority from the Aude (8 objects), the Narbonensian corridor along which Tarraconensian goods moved overland and by river toward the Atlantic and northern Gaul; a single object from Haute-Corse attests to the maritime route as well. Italy is equally represented (9 objects: 7 from Roma, 1 from Napoli, 1 from Ostia), confirming the role of the capital, its harbour city, and Campanian ports as endpoints of the western Mediterranean wine trade. A single object from Zaragoza records inland Hispanian circulation. Taken together, the pattern — Carthage, southern Gaul, and Rome as the principal nodes — integrates Laietanian wine firmly into the documented structure of early Imperial long-distance commerce in the western Mediterranean.
