baking, Roman

The earliest Roman bakers almost certainly made bread for their own households, but not for sale to the public. Pliny the Elder tells us in his Natural History (18.28) that among the quirites of Rome’s past, women baked the family’s bread, an observation he bases on comparisons with contemporary non-Roman peoples. Yet modes of domestic production were probably as diverse as the families themselves; early terracotta figurines from the eastern Mediterranean show women, men, and children all participating in the production of bread (Fig. 1).

Moreover, the figurine shows both milling and baking, processes that remained interlinked until the end of antiquity. Even later commercial bakers seem also to have been millers. Medieval bakers, however, rarely milled their own grain. To some extent, this resulted from the advent of new technologies such as watermills and windmills, but the watermill, at least, was available from the 1st century bce onward (Vitr. De arch. 10.5.2; Strab. Geo. 12.3.30).1 Bakers who purchased flour premilled, rather than milling their own grain, do not appear to have been the norm until the 6th or 7th century ce.

Whoever the early domestic bakers were, they had at their disposal a number of methods to produce their bread. The bread making described by Pliny (18.26) suggests that much Roman bread was of the sourdough sort. Flour, from any number of grains, was mixed with some sort of leavening agent. Pliny describes the use of fermented grape juice (mustum), a soured barley cake, or even beer foam, but he makes clear that these practices were abnormal or antiquated in his time. The normal method, says Pliny, was to save some dough before salt is added. It was mixed with water and allowed to ferment into a sourdough starter (a sort of fermented slurry) and added to the next day’s dough to serve as the leavening agent. Although sourdough bread was probably the norm, what characterises Pliny’s description of Roman bread is the variety of types, made from different grains and taking myriad forms. In general, white leavened bread was preferred to coarser brown breads. Certain types of bread were even associated with higher or lower social status; for Juvenal (Sat. 5.74–5) “to know the color of one’s bread” meant knowing one’s place in Roman society, and jokes about giving darker bread to sub-elite guests were common.2 Carbonised loaves of bread were found in some bakeries in Pompeii, still in their ovens.

Most domestically produced bread was probably not baked in masonry ovens such as those found in the bakeries at Pompeii and Ostia, but in terracotta baking vessels such as the testum and the clibanus.3 Cato (Agr. 75) refers to the process as sub testu (“under brick”). These devices were widely used from the 3rd to the 1st century bce. Following the 1st century bce, testa and clibani persisted in rural contexts, but became extremely rare in urban ones.4 It is likely that the disappearance of these baking technologies resulted from the increasing commercialization of baking in Roman cities. Indeed, rapidly advancing baking and milling technologies during the last few centuries bce corroborate intensified commercial baking in the Roman world.

When the first commercial bakers emerged in Rome is somewhat unclear owing to a dearth of archaeological evidence, and distinguishing the earliest commercial bakers from their domestic counterparts may be impossible. The issue is complicated by Pliny the Elder, who says that there were no bakers in the city until the war with King Perseus in 171 bce (18.28), though the earliest literary accounts of bakers in Rome pre-date Pliny’s assertion by a generation or so. Moreover, the etymology of the Latin words for “baker” and “bakery” leads to further confusion. According to Varro (Rust. 1.63) the terms for commercial bakers, pistores, and their bakeries, pistrina, were derived from the verb pinsere, “to grind or pound.” The earliest pistores, then, may have actually been millers rather than bakers, and the Roman baking industry may have grown out of commercial milling.5 Later pistrina were places of both milling and baking, suggesting that craftsmen or workshops could bear a title that did not entirely reflect the reality of their commercial endeavors. In Plautus’s late 3rd century bce play Asinaria (l. 200), a character notes that bread is purchased from a pistor, suggesting that at least some pistores were baking as well as milling at an early point in the history of Roman commercial baking.

The first archaeological evidence for commercial baking in Rome dates to the late 1st century bce, discovered just outside the Porta Maggiore.6 This bakery, if it was in fact a pistrinum, is very poorly preserved; indeed, little material evidence for commercial baking remains extant in Rome from any period. Despite the lack of evidence from Rome, bakeries at Pompeii and from around the Roman Empire offer possible comparanda for the early bakers in the city. Bakeries have been found around the empire, including around thirty in Pompeii, two in Herculaneum, six in Ostia, two in Italica (Spain), and eight in Volubilis (Morocco) (Figs. 26).

Many bakeries in Pompeii are located in large homes, like that of the Casa di Laberinto, integrated with the areas of low accessibility and visibility in the house most commonly associated with the household’s more modest residents: slaves (Fig. 7).

Slaves, as members of the broadly defined Roman familia and residents in the elite domus, surely performed the vast majority of the labour. Some slaves were probably in charge of oversight as proxies (institores) for their masters, while others performed brutal physical labour.7 In Plautus’s Asinaria (l. 709), impertinent slaves are threatened with despatch to the bakeries as a punishment, and the bakery slaves described by Apuleius (Met. 9.12) are whipped, chained, and beaten black and blue. When needed, free poor may have also been employed in Roman pistrina. A graffito from Pompeii suggests that a day’s work earned someone one denarius and a loaf of bread: OPERARI PANE DENARIV (CIL IV 6877), though the exact nature of the labour is not specified. Work for pay may be suggested by another graffito, with illustration (GraffPalatino I.289), from the Palatine hill in Rome that reads, “Work, little ass, as I have worked and you shall profit.”

Although some bakeries in Pompeii are located in large, elite houses, most pistrina around the Roman world are independent of such large houses. In the Casa dei Casti Amanti in Pompeii, the commercial production of bread is integrated into the house’s dining rooms and other spaces with elaborate decoration, typically associated with elite domesticity Fig. 8).

Unlike that of the bakeries in large houses, production is in areas of high visibility and high accessibility. Other bakeries, such as the Forum Bakery at Volubilis or the so-called Pistrinum of Sextus Patulcus (Insula Orientalis II.8) in Herculaneum, seem entirely consumed by production space (Figs. 9 and 10).

Bakers working in such bakeries may have lived in the pistrinum as well, albeit in a more modest fashion than the residents of the Casa dei Casti Amanti. The possibilities are innumerable, but the space in all these smaller bakeries suggests intimacy and closeness. Family members were probably responsible for the operation of such bakeries, assisted by the slaves or hired help that the family could afford. Customers were almost surely familiar faces.

Bakers, particularly in the Latin West, frequently used imagery derived from their trade on their tombs, on shop signs, and even on signet rings. Such iconography often shows a single millstone with a donkey, such as the funerary monument of M. Careius Asinus from Narbonne or a signet ring of unknown provenance (see Figs. 11 and 12).

Never, in the provinces, does one find monumental tombs of bakers or programmatic, complex iconography exalting the craft of a baker. In Rome, in contrast, there are signs as early as the 1st century bce that the commercial baking industry might be developing in ways different from those in the empire’s smaller urban centres. On the 1st-century bce Tomb of the Baker, Eurysaces is described in one inscription (CIL VI 1958a) as a pistor redemptor, likely a contract baker, perhaps providing bread to some state institution (Fig. 13).8

No such contract bakers are evident in the small bakeries around the empire, and it may explain the grand size of the tomb. The form of the tomb consists of hollow roundels supported by long cylinders, also hollow. Some have proposed that the hollow roundels and cylinders represent grain measures,9 but the most recent scholarship maintains that the round holes are kneaders of the sort found in Pompeii, in Ostia, and around the Mediterranean (Fig. 14).10

Squares evident in the roundels are also apparent in the truncated cylinders on the broken eastern façade, and the same squares are observable in kneaders (Fig. 15).

Eurysaces may have wanted to showcase a new technology on his tomb; kneaders appear to have been a recent innovation. The recently published Romolo Relief is roughly contemporaneous with the Eurysaces’ tomb, but no kneaders are depicted in the scene.11

The most discussed attribute of the tomb, however, is the frieze showing scenes of commercial baking, which originally existed on all four sides but is only partially preserved on three (Fig. 16).

The frieze depicts all the processes necessary for the production of bread. The number of figures and their varying attire suggest high levels of production and a complex internal hierarchy within Eurysaces’ operation, congruent with the wealth necessary to have built such an opulent tomb. Indeed, there is ample legal evidence to suggest not only that Rome’s bakeries were producing on a larger scale, but also that the state was going to some effort to ensure high levels of production. For example, Trajan offered concessions to Junian Latins and pistores in general if they operated a bakery that milled at least 100 modii of grain a day, enough to feel at least a thousand people (Gai. Inst., 1.34; Digest (Paulus) 27.1.46).

By the 2nd century ce, Rome’s bakeries were approaching mass production of bread, if Ostia’s baking industry is any indication. The so-called Molino at Ostia (I.13.4) housed six or seven millstones, four kneaders, and an oven 5m in diameter (Fig. 17).

In fact, the oven in the Caseggiato dei Molini (I.3.1) is so large that it has been suggested that it contained some sort of rotating “lazy Susan” so that the baker could utilise its entire capacity, as evidenced by a series of grooves in the sides of the oven (Figs. 18 and 19).12

But the ovens are all oval, and so no rotation within them would be possible; it seems more likely that the Ostian ovens baked bread in trays, which were loaded using some sort of long pole that made the marks on the sides of the ovens. Indeed, the lateral apertures behind the baking space would have allowed the baker to move the pole beyond what the wall would otherwise have allowed (Fig. 20).

Operating one of these huge bakeries may have been a hardship. The 3rd-century sarcophagus of Annius Octavius Valerianus from Rome, now in the Vatican, shows scenes of commercial baking not unlike those on Eurysaces’ tomb. But in the inscription (CIL VI 11743), Valerianus laments his poor fortune in life and welcomes the escape of death.

The 3rd century ce witnessed the rise of a new technology which would forever change the Roman commercial baking industry: the watermill. Some have argued that the introduction of this technology spurred a hyperspecialisation of bakers and millers and the creation of two separate crafts in late 4th century ce.13 But Vitruvius (De arch. 10.5.2) and Strabo (Strab. Geo. 12.3.30) describe such devices as early as the 1st century bce.14 Even if watermills were only being implemented in the 3rd century ce and later—and there is significant evidence to the contrary—the mills on the Janiculum could not have provided for more than 5 or 6 percent of the city’s population.15 Indeed, there is significant evidence to suggest that Roman pistores around the empire continued to mill and bake well into the 6th century ce.16 It is only at the very end of antiquity, when new systems of supply and consumption superseded the old Roman ways of doing things, that the miller and the baker finally became two separate professions.
