The Value of Columella

Agriculture is central to the human experience. The annual cycle of planting and harvesting has provided the basis for how we work and how we relax. Nothing is more valuable for understanding a society than how they get their food. Because food and agriculture are such fundamental aspects of human society, understanding them provides insights into the worldview and lifestyle of a culture.
Lucius Junius Moderatus Columella was born in Gades (modern Cadiz) in the southwest of Spain, likely early in the 1st century CE. He is known for his single work De Re Rustica, a twelve book commentary on agriculture. The shorter work De Arboribus is attributed to Columella, but its exact authorship is unknown. It is believed that De Arboribus is the second part of a shorter four book treatise on Agriculture. This seems to be supported by the lack of any concluding remarks; the book just ends with a short discussion on planting violets and rosebushes.
Book IX of De Re Rustica deals with two aspects of a farming life that are generally wilder than most: raising game animals and beekeeping. Most of the book is dedicated to beekeeping, but the chapter on establishing game reserves was quite interesting. I’ve read quite a bit about beekeeping, but very little about stands of deer, hares and boars. Columella recommends using a forest within sight of the farm and building a wall or fence around to keep the animals in. He also recommends digging natural looking troughs so that even if there isn’t a stream or pond in the woods since the game animals won’t be free to wander. He also recommends taming the animals to a certain degree, not so much that they don’t provide a good hunt, but enough that they will accept feed from humans. Columella claims that the best time to slaughter a boar or roebuck is within four years, afterwards the meat becomes too tough and lean to be enjoyed. Deer apparently stay tender longer, as Columella doesn’t attach any particular time limit on when they can be eaten. Hares need to be eaten earlier because their lives aree so much shorter. This system of maintaining game parks ensure that meat will be readily available when a farmer doesn’t want to slaughter one of the domesticated livestock whose value comes from the labor, dairy, wool, or eggs, animals that are more useful alive and in the fields than dead and on the table. Columella notes that these game parks are only a viable option for wealthier farmers who are able to support animals that don’t contribute anything to the farm besides their meat.
The rest of Book IX is dedicated to beekeeping and how to harvest honey and wax. Columella describes how hives should be constructed and what materials work best. He also provides a useful list of what plants and trees should be available to produce the best honey. One of the most interesting parts of the book is where he discusses the various diseases to which bees are susceptible. In an era where many hives are being ravaged by Colony Collapse Disorder, it is important to understand the value of bees. Columella makes clear that there are many diseases that can affect bees and outlines the cures that Roman farmers used when disease struck the hives. His techniques for gathering wild swarms are still the primary methods that beekeepers use today. It was interesting that Columella spent time discussing bee kings, when in fact as we know the queen bee is the leader of the hive and that all of the males are drones. This speaks to the male orientation of Roman society, and while it is factually incorrect the techniques that Columella recommends for handling king bees worked on the queens, they aren’t tied questions of gender.
The primary focus of De Arboribus is not, as the title may suggest, the cultivation of trees and orchards. Rather, most of the book is dedicated to the preparation and maintenance of vineyards. Columella writes on which fields are best suited for vines and how to prepare the land for the plants. Just as he described the diseases that bees face and their requisite cures, he also shares methods for protecting vines from both the dangers of disease and the ravages that fog and mildew can visit on a crop. His advice on pruning and trimming is still followed by many gardeners and arborist today. He advises that plants not be cut back until they’re in their third year. This is in line with the contemporary adage that trees “sleep, creep, and leap” in the first three years after planting. Columella also has two very interesting sections on transplantation and grafting. His grafting techniques demonstrated that contrary to popular belief at the time, trees did not have to be similar to be grafted together, as he demonstrated by grafting a fig and olive tree together. The section of De Arboribus in which Columella writes on trees is just as interesting as his work with vines. He describes methods of orchard preparation and has planting advice for a number of trees, both for their fruits and flowers. He focuses most on olive trees with shorter sections on fruit and nut trees.
The works of Columella are valuable to both scholars and laypeople. One, they’re fascinating, farming has been a central aspect of human existence since it was discovered and seeing how food was produced in one of the greatest empires is valuable for how interesting it is. Beyond reading for pure pleasure, works on ancient agriculture can help modern farmers with their own production methods. Organic farming has seen a major revival in recent years and ancient agriculture is certainly organic. The techniques described in De Re Rustica and De Arboribus paired with modern understanding of botany and agricultural sciences would be helpful for farmers seeking to recapture preindustrial agricultural production methods.  While the specific strains of plants that Columella recommends for various purposes would not be available, modern equivalents could easily stand in.
Columella is also provides a window into what aspects of farms people most valued in the Early Imperial Period. He mentions a number of fruit trees, including apples, pears and figs, but not any oranges or other citrus fruits. This indicates, even to a reader unfamiliar with the text, that Columella’s focus is on the more temperate climes of the Roman heartland, rather than the warmer regions where oranges flourish, like his native southern Spain and nearby North Africa. This provides important contextual information for the reader and allows a greater understanding of Columella’s purpose in writing.

            Ancient agriculture is often overlooked in favor of more glamorous areas of classical study. This is at the expense of all the knowledge and insight that we can glean from methods of food production and other products brought about by agriculture, including textiles and medicines. As the most thorough treatment of Roman agricultural practices there are few works as valuable as those of Columella for the study of this essential aspect of classical life. Columella understood the forces that shape society, from the farmers in the provinces to the elite in Rome, all lives were driven by agriculture.
