Sulcus Primigenius

Sulcus Primigenius, literally the original furrow, refers to the furrow plowed by priests leading two oxen in an archaic Roman ceremony that established a sacred area in the foundation of a new city.

The custom of the sulcus primigenius was looked at by the Romans themselves as very old. It was probably adopted from the Etruscans. Romulus performed this rite to found Rome and killed Remus because he jumped over the furrow he had plowed.

Dionysos von Halicarnassus (Ant. Rom. 1. 88) suggests that this act of Romulus has served as example for all later Roman city founding. A foundation ceremony, with two priests leading a pair of oxen, is frequently depicted on the reverse of coins of the Roman colonies including the following cities: Brundisium, Philippi, Caesarea Maritima, Caesaraugusta, Akko-Ptolemais, Ninica Claudiopolis, Berytos, Petra, Rhesaena, Antiochia.

Gaebler describes the practice based on coin pictures and the description of Hyginus Gromaticus: The act of founding the colony has been done in this way: When the colones have arrived and the auspices have been obtained, the legatus coloniae deducendae, the head covered with a part of his toga which was applied in a special kind (ritu Gabino), where a part of it was tied around the waist as belt, plowed around the area which was provided for distribution a furrow (sulcus primigenius). This was done counterclockwise with a dyad which has to be on the right side (outwards) a bull and on the left side a cow. In doing so they held the bent handle of the plow so that the clod fell inwards. At that places were later should be the gates they lifted the plow so that the furrow here was interrupted (Varro LL.5.143)

Already previously the territory has been measured by agrimensores and divided in square areas (centuriae) and these further segmented in a certain number (sortes acceptae). Now the distribution of land began. This was done - as we know by the writings of the gromatic Hyginus - by lot and in three stages: at first the candidates were arranged in decuriae or in conternationes (10 or 3 recipients per centuria), then the order in which this community (consortia) should draw the lots, and not before this was managed the actual drawing of lots sortitio centuriarum has occurred.The legatus then has taken place on the sella curulis and before his feet the urn of lots has stood. From this urn the lots (probably small inscribed wooden rods) were drawn and everyone assigned his piece of land.
The ritual act of the founding therefore has consisted of two equal important procedures: the defining of the area by the primigenius sulcus, which confirms the connection to the ager publicus populi Romani, and the distribution of the field lots by the legate (sortitio).
