Suburban villas on the edge of cities also occurred, such as the Middle and Late Republican villas that encroached on the Campus Martius, at that time on the edge of Rome, and which can be also seen outside the city walls of Pompeii. These early suburban villas, such as the one at Rome's Parco della Musica or at Grottarossa in Rome, demonstrate the antiquity and heritage of the "villa suburbana" in Central Italy. It is possible that these early, suburban villas were also in fact the seats of power of regional strongmen or heads of important families ("gentes"). A third type of villa provided the organisational centre of the large holdings called "latifundia", which produced and exported agricultural produce; such villas might lack luxuries. By the 4th century, "villa" could simply connote an agricultural holding: Jerome translated in the Gospel of Mark (xiv, 32) "chorion", describing the olive grove of Gethsemane, with villa, without an inference that there were any dwellings there at all.
