⭐ Core Definition: Roman mile

The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of length; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. The statute mile was standardised as a unit of length between the Commonwealth of Nations and the United States by an international agreement in 1959, when the yard was formally redefined with respect to SI units as 0.9144 metres, making the mile exactly 1609.344 metres (1.609344 kilometres). For everyday use, five miles equates roughly to eight kilometres.

With qualifiers, mile is also used to describe or translate a wide range of units derived from or roughly equivalent to the Roman mile (roughly 1.48 km), such as the nautical mile (now 1.852 km exactly), the Italian mile (roughly 1.852 km), and the Chinese mile (now 500 m exactly). The Romans divided their mile into 5,000 pedes (lit.'feet'), but the greater importance of furlongs in the Elizabethan-era England meant that the statute mile was made equivalent to 8 furlongs or 5,280 feet in 1593. This form of the mile then spread across the British Empire, some successor states of which continue to employ the mile. The US Geological Survey now employs the metre for official purposes, but legacy data from its 1927 geodetic datum has meant that a separate US survey mile (6336/3937 km) continues to see some use, although it was officially phased out in 2022. While most countries replaced the mile with the kilometre when switching to the International System of Units (SI), the international mile continues to be used in some countries, such as the United Kingdom, the United States, and a number of countries with fewer than one million inhabitants, most of which are UK or US territories or have close historical ties with the UK or US.

👉 Roman mile in the context of Arabic mile

The Arab, Arabic, or Arabian mile (Arabic: الميل, al-mīl) was a historical Arabic unit of length. Its precise length is disputed, lying between 1,800 metres (5,900 ft) and 2,000 metres (6,600 ft). It was used by medieval Arab geographers and astronomers. The predecessor of the modern nautical mile, it extended the Roman mile to fit an astronomical approximation of 1 minute of an arc of latitude measured along a north–south meridian. The distance between two pillars whose latitudes differed by 1 degree in a north–south direction was measured using sighting pegs along a flat desert plane.

There were 4,000 cubits in an Arabic mile. If al-Farghani used the legal cubit as his unit of measurement, then an Arabic mile was 1,995 meters long. If he used al-Ma'mun's surveying cubit, it was 1,925 meters long or 1.04 nautical miles (1.93 km)Al-Farghani gave 20,400 miles as the circumference of the Earth in Elements of astronomy on the celestial motions (p. 31.) in 833. He added that 1 mile is equal to 4000 cubits. This leads to 1 Arabic mile being ~1.96 km.

Roman mile in the context of Ara Pacis

The Ara Pacis Augustae (Latin, "Altar of Augustan Peace"; commonly shortened to Ara Pacis) is an altar in Rome dedicated to the Pax Romana. The monument was commissioned by the Roman Senate on July 4, 13 BC to honour the return of Augustus to Rome after three years in Hispania and Gaul and consecrated on January 30, 9 BC. Originally located on the northern outskirts of Rome, a Roman mile from the boundary of the pomerium on the west side of the Via Flaminia, the Ara Pacis stood in the northeastern corner of the Campus Martius, the former flood plain of the Tiber River and gradually became buried under 4 metres (13 ft) of silt deposits. It was reassembled in its current location, now the Museum of the Ara Pacis, in 1938, turned 90° counterclockwise from its original orientation so that the original western side now faces south.

Roman mile in the context of Caudium

Caudium (modern Montesarchio) was the main city of the ancient Caudini tribe in Samnium situated on the Appian Way between Beneventum (modern Benevento) and Capua, in what is now southern Italy. It was 21 Roman miles from Capua, and 11 from Beneventum. It, or nearby Arpaia, became the seat of an early bishopric, which is now a Latin Catholic titular see.

Roman mile in the context of Miliarium

A miliarium (Classical Latin: [miːllɪˈaːrɪ.ũː ˈau̯rɛ.ũː]) was a cylindrical, oval or parallelepiped column placed on the edge of Roman roads to mark the distances every thousand passus (double Roman steps), that is, every mile. Today, this is equivalent to a distance of approximately 1480 meters. The stone known as the Milliarium Aureum was the point used to indicate the distance to Rome from any point in the Roman Empire.

These physical markers of distance corresponded to the abstract route descriptions found in Roman itinerarium, which were text-based lists of cities, stops, and the distances between them.
