Pertica (unit)
The pertica (from , measuring rod) was a pre- metric unit of either length or area, with the values varying by location. For a similar unit in Northern Europe, see perch. Ancient Rome In the Ancient Rome, pertica, also called decempeda, was a unit of length, usually equal to 10 Roman feet (''pedes''), or approximately 2.96 meters. The variants of pertica contained 12 and 15 pedes. Isidore of Seville (per Codex Gudianus) states that sometimes a pertica of 10, 12, 15, or 17 pedes was used by agrimensores (Roman land surveyors) to accommodate the richness of the soil and approximately even the yield per unit area. Kidson highlights the near-perfect match between the pertica of 17 pedes and the English version of the perch. The same names, pertica and decempeda, were used for the surveyor's tool, a rod of the corresponding length with subdivision into smaller units, similar to the Ancient Greek ''kalamos''. Italy The linear unit in Italy was about 3 meters, area unit contai ...

Allegory Of Measurement (Giovanni Zaratino Castellini)
As a literary device or artistic form, an allegory is a narrative or visual representation in which a character, place, or event can be interpreted to represent a meaning with moral or political significance. Authors have used allegory throughout history in all forms of art to illustrate or convey complex ideas and concepts in ways that are comprehensible or striking to its viewers, readers, or listeners. Writers and speakers typically use allegories to convey (semi-) hidden or complex meanings through symbolic figures, actions, imagery, or events, which together create the moral, spiritual, or political meaning the author wishes to convey. Many allegories use personification of abstract concepts. Etymology First attested in English in 1382, the word ''allegory'' comes from Latin ''allegoria'', the latinisation of the Greek ἀλληγορία (''allegoría''), "veiled language, figurative", literally "speaking about something else", which in turn comes from ἄλλος ( ...

Ancient Roman Units Of Measurement
The units of measurement of ancient Rome were generally consistent and well documented. Length The basic unit of Roman linear measurement was the ''pes'' (plural: ''pedes'') or Roman foot. Investigation of its relation to the English foot goes back at least to 1647, when John Greaves published his ''Discourse on the Romane foot''. Greaves visited Rome in 1639, and measured, among other things, the foot measure on the tomb of Titus Statilius Aper, that on the statue of Cossutius formerly in the gardens of Angelo Colocci, the congius of Vespasian previously measured by Villalpandus, a number of brass measuring-rods found in the ruins of Rome, the paving-stones of the Pantheon and many other ancient Roman buildings, and the distance between the milestones on the Appian Way. He concluded that the Cossutian foot was the "true" Roman foot, and reported these values compared to the iron standard of the English foot in the Guildhall in London William Smith (1851) gives a value ...

Decare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), that is, square metres (), and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare ("hecto-" + "are") was thus 100 ''ares'' or  km2 ( square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa () and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, is the o ...
