Ancient Measurement Terms:

Acre (area):

(Anglo-Saxon field.) The land area that can be ploughed by one ox team in a day - actually in a morning because the Oxen would need resting in the afternoon: They would trudge 11 miles while ploughing an acre. Traditionally in the strip field farming system, an area 40 rods long by 4 rods wide (ie. 220 yards by 22 yards). Sometimes used as a measure of width: One acre = 4 Rods wide. One tenth of a square furlong. Similar to the French Journal, and German Morgan or Tagwerk. The modern acre is 4840 square yards.

Amercement:

Financial penalty inflicted at the MERCY of the King or his justices for various minor offences. The offender is said to be "IN MERCY" and the monies paid to the crown to settle the matter was called amercement (See also Fines).

Arpent:

A measure of land roughly equal to a modern acre.

Bushel:

Volume. A dry measure of 8 gallons, or 4 pecks.

Cart-load (also called load):

Weight. See: fother.

Carucate:

A measurement of land, equal to a hide (used in Dane law).

Danegeld or Danegelt:

The money paid by Anglo-Saxon Britain to persuade the Danes to not invade the South and West. Now means money extorted by threats.

Denarius:

The English silver penny, hence the abbreviation "d" and the coin in most common circulation. Although they were sometimes "clipped" or "debased," the English silver penny contained a standard weight of silver and so could be traded across Europe. Introduced by the Romans.

Exchequer:

Financial department of the royal government. The chief officers of the Exchequer were the Treasurer, the Chancellor and the Justiciar. Sheriffs, in their role as regional chief accountants, presented reports to the exchequer at Easter and Michaelmas.

Ferding:

Administrative unit of land. Fourth part of a hundred. (Not necessarily exactly a quarter.)

Ferling or Quarter:

Quarter of a Virgate.

Fief de Haubert:

11th century French term equivalent to the term Knight's Fee because of the coat of mail (hauberk) which it entitled and required every tenant to own and wear when his services were needed. This provided a definite estate in France, because only persons who had this estate or greater were allowed to wear hauberks.

Fodder:

Weight. See: fother.

Fother (also called fodder, foder, fodur, cart-load, load, wain, waine, wey, etc.):

Weight. A cart-load. About 19½ hundredweight, dependent upon material. Also, six sacks where each sack is five fotmal.

Volume. 40 bushels or 320 gallons.

Also, "lots of," "a large quantity," "a huge amount," etc.

Fotmal (also called fotmæl, fotmel, votmel, etc.):

Length. One foot (foot-length, foot-print or foot-space).

Weight. About 70 pounds of lead. (Definitions varied between 70 and 72. Weight also depended upon material.) A thirtieth of a fother. A fifth of a sack. 5 stone.

Comment: A fotmal of lead would occupy about one tenth of a cubic foot. This could form an ingot about 12 x 5 x 3 inches. A man could lift and carry this weight a short distance. A pack animal could carry two fotmal as a balanced load — one on each side of its back.

In 1391, each votmel of old lead roof sheets taken from the roof of Marlborough Castle was valued at 4 shillings.

Lead sheeting a tenth of an inch thick weighs 6 pounds per square foot. At this thickness, a fotmal of lead would produce about 12 square feet of lead sheets.

Comment: This unit does not seem to match the Roman practice: Lindsey Davis's entertaining novel "The Silver Pigs" is set during the Roman occupation of Britain. These Silver Pigs are actually lead ingots made from British lead ore which also contained about 130 ounces per ton of valuable silver. The ingots are said to be 20 x 5 x 4 inches with the Emperor's name and date stamped on one long edge, to weigh 200 Roman pounds, and to contain 24 ladles of molten ore.

Furlong:

(Anglo-Saxon field.) The length of a plough furrow - ie. Furrow-long. In the strip field farming system, the length of the field strip ploughed before turning the ox team to plough the next furrow.

Geld or Gelt:

Tax. As in Danegeld, the money raised and paid by Anglo-Saxon Britain to persuade the Danes to not invade the South and West.

Hide:

A unit of measurement for assessment of tax, theoretically 120 acres, although it could vary between 60 and 240 acres. By custom it was the land that could be cultivated by an ox plough team in one year. In the Devonshire Domesday Book, it seemed to average about 64 acres.

Hundred:

Anglo Saxon institution. Subdivision of a Shire. Theoretically, but hardly ever, equalled one hundred hides. Generally had its own court which met monthly to handle civil and criminal law. Equivalent to the ancient Norse Wapentake. There was a Hemyock Hundred.

Hundredweight:

Weight. 4 quarters ie. 8 stones or 112 pounds.

Jar:

Electrical unit. Admiralty practical unit of electrical capacitance until mid 1930s. Based upon the Leyden Jar. A standard Admiralty glass pint tankard covered with tin-foil as the outside electrode and filled with 1 pint of brine as the inside electrode had a capacitance of about 1 Jar. Now replaced by the Farad. 900 Jars = 1 micro Farad.

Knight's Fee:

In theory, a Fief which provided sufficient revenue to equip and support one knight. This was approximately twelve hides or 1500 acres, although the terms applied more to revenue a fief could generate than its size; it required about thirty marks per year to support a knight.

Last:

2 wey. Definitions varied, usually about 2 tons, or 60 fotmal, or 80 bushels, or 640 gallons.

League:

In the Devonshire Domesday Book, usually 1½ miles.

Leet:

The term used for a subdivision of land in Kent equivalent to a hundred.

Load (also called cart-load):

Weight. See: fother.

Long Ton:

Weight. See ton.

Man-at-arms:

Soldier holding his land, generally 60-120 acres, specifically in exchange for military service. Sometimes called a Yeoman.

Manor:

Small holding, typically 1200-1800 acres, with its own court and probably its own hall, but not necessarily having a manor house. The manor as a unit of land was generally held by a knight (knight's fee) or managed by a bailiff for some other holder. In later years, the power of the manor declined progressively in favour of the vill.

Mark:

Money. Normally means the silver mark, a measure of silver, generally eight ounces, accepted throughout medieval western Europe. Although they were sometimes "clipped" or "debased," the English silver penny contained a standard weight of silver and so could be traded across Europe. In England the mark was worth thirteen shillings and four pence, ie. two thirds of £1. Equivalent to present value of the Euro.

The gold mark was worth £6.

Maundy Money:

Ceremonial coins given to the poor by the British Monarch, on Maundy Thursday, the Thursday before Easter. Consists of silver 4, 3, 2, and 1 pence coins. Each recipient is given coins which total the Monarch's age.

Peck:

Volume. A dry measure of 2 gallons, or ¼ bushel.

Also, a "large" amount.

Plough (Land of one plough):

The area of arable land capable of being tilled by one plough team. Equivalent to one Hide.

Pound (weight):

16 ounces (Avoirdupois).

Quarter (weight):

2 stones ie. 28 pounds.

Riding:

Administrative unit of land. Third part of a shire, eg. the Yorkshire Ridings (North Riding, East Riding, West Riding) which were established in the 9th century by the Danes. (Not necessarily exactly a third.)

Sack:

Weight. Five fotmal (of lead).

Shilling:

Measure of money used for accounting purposes and equal to 12 old pennies. Until modern times, there was no actual coin. Small silvery coin. (Now replaced by 5 new pence.)

Short Ton (weight):

2000 pounds.

Slug (mass):

British engineering unit. 32.174 pounds mass. A mass numerically equal to the acceleration of standard gravity (32.174 feet per second per second). When subjected to a force of 1lb weight, a 1 slug mass will accelerate at 1 foot per second per second.

Small Holder:

Middle ranking peasant, farming more land than a cottager but less than a villein. A typical small holder would have 10-20 acres. Also known as a Bordar.

Stone (weight):

14 pounds.

Sulong:

Measurement of land in Kent. Equal to two hides.

Third Penny:

The local earl's one-third share of fines in shire or hundred courts, often allocated afterwards to a particular manor or church as income.

Tithe:

One tenth of a person's produce and income, due as a tax to support the church.

Ton (weight):

20 hundredweight or 2240 pounds. The "Long Ton."

Vill:

Administrative unit containing about 5 to 10 Hides and inhabitants. Equivalent to the secular parish. The vill usually contained several manors. As the feudal system declined, the vill took over importance from the hundred and manor. Later, the parish took on the duties and responsibilities, for example during the nineteenth century, the sick, poor, and destitute sometimes relied on the parish for aid.

In Devonshire at the time of the Domesday Book there were 980 vills containing about 9000 hamlets or farms.

Ideas return! The UK government policy in recent years has been to devolve many duties and responsibilities to secular parish councils. (Note. These secular parish councils may share common boundaries with the Church of England parishes, but are different institutions.)

Villein:

Wealthiest class of peasant. They usually cultivated 20-40 acres of land, often in isolated strips.

Virgate:

One quarter of a hide. However, in the Devonshire Domesday Book, was used as a unit of tax rather than of land area. Hemyock was assessed as paying Geld for one Virgate.

Votmel:

Weight. About 70 pounds of lead. See: Fotmal.

Wain (also called cart-load, load, wain, etc.):

Weight. See: Cart-load. About 19½ hundredweight, dependent upon material. Also, six sacks where each sack is five fotmal.

Also, "lots of," "a large quantity," "a huge amount," etc.

Warpentake:

Weapon-taking. Sub-division of land in areas formerly under Norse control - including Northern and Eastern areas of Britain -equivalent to Anglo Saxon Hundred.

Wey:

Weight or volume. See: Cart-load. About 19½ hundredweight, dependent upon material. Also, 320 gallons, or 40 bushels, or 30 fotmal.

Yeoman:

See Man-at-Arms.

Yoke:

A measurement of land in Kent equal to one quarter of a sulong.
