Monumentum anacyranum

Index rerum a se gestarum: sive Monumentum anacyranum. Ex reliquiis Graecae interpretationis

The name Monumentum Ancyranum refers to the Temple of Augustus and Rome in Ancyra (modern Ankara, Turkey), or to the inscription Res Gestae Divi Augusti, a text recounting the deeds of the first Roman emperor Augustus, the most intact copy of which is preserved on the walls of this temple.





The Roman Centuriation in the Middlesex District

The Roman Centuriation in the Middlesex District. (Brentford Printing and » 20 Jun 1908 » The Spectator Archive

The Roman Centuriation in the Middlesex District.
(Brentford Printing and Publishing Company. 3s. 6&)—
This is an addendum to Mr. Montagu Sharpe'e "Antiquities of Middlesex" A centuria was a square plot of land containing fifty iugera, equivalent to thirty-one and a quarter acres. This was the measure used in dividing the land of a conquered country. Each Roman citizen had four centuriac ; part was restored to the natives ; odd bits and unoccupied lands were leased out; forests, &c., were dealt with on the same principles. Mr. Sharpe writes about the details of this division—boundaries, landmarks, &c.—and applies his deductions to the Middlesex region, with some portions of the adjoining counties. He makes out eight territories (named "Break- spear's," "Colne," "Pontes "—these are in the west—" Ridge," "Sulloniacae," " Harrow," " Home," "Lea "). We cannot discuss the details, but we may point out a highly interesting list of landmarks as related to the road system given on p. 14.

For some time past it had been noticed that many fragments of its ancient rural ways ran in parallel lines, and were crossed at right angles by similar ones, which in the several districts of the county were distinguished by a different orientation. Thus in the northeastern division the direction of the cardinal ways was from north to south: in the southern portion between the Brent and the Lea rivers, and into Essex, they pointed south-south-east. Over the south-western area and beyond the Colne into Buckinghamshire the course was south by west, and in the north-western district they were again south-south-east. Passing into that part of the Middlesaxon province lying south of the upper Colne and Lea, but now in Hertfordshire, the two orientations were {490} respectively south-east by south, and south by east. A further feature was that many crossways occurred at equal intervals, and along one road five in succession were found at distances of 120 Roman poles or 388 yards, two being roads, two foot paths, and the other an ancient field boundary, presumed to have been formerly a plough balk or a footway.
It was manifest that this laying out of land amounting to 181,000 acres could not have been the result of chance, but must have been carried out at a time when the soil was mostly in its primitive condition, by a conquering race who had seized it, and who were accompanied by skilled land measurers. All this pointed unmistakably to the Romans and their corps of agrimensores, trained in applied geometry and using scientific instruments. The writings of the Gromatici Veteres were next consulted for information as to the manner in which Roman lands were surveyed and laid out, and it is worthy of note that one of the most eminent of these writers was Sextus Frontinus, Propraetor over Britain from a. d. 74. Among the more enduring bench or land marks used by Roman surveyors were mounds of earth (up to the size of a small haystack), stones, and trenches, and in these three respects important discoveries have been made in the county. A mound (botontinus) is to be seen both in Cranford and in Syon parks, also at Hampstead, Stanmore, Hadley—where there are two—and just out of the county at Salthill, Slough. Two others have not long ago been levelled, one by Bushy Park and the other at Hillingdon, while local names apparently preserve the sites of half a dozen more. Four stones are still in situ; two marked on old maps no longer exist, and the former positions of several others can be located. Two trenches are still to be seen.
A map showed that these boundary marks and the remnants of the oriented ways were naturally co-related, that each district had been of nearly equal area, rectangular in form, and contained by a boundary line, the course of which was disclosed by the botontini and stones. It was also seen that these districts or pagi were in general identical in area with those of the later hundreds of the Saxon period, as set forth in Domesday. From the orientation of the pagi, the territorium of the Londinium canton appeared to extend from the foot of the Chiltern hills across Middlesex and into Essex; the pagi had been laid out by lines (quintarii) crossing one another at right angles, and so forming possessae, each of which according to the text-book, and in fact, contained 1,300 jugera equal to 810 statute acres. These in turn could be divided into 25 laterculi or small centuriae of 50 jugera lying in rows of five, plus an area equal to a centuria distributable over a possessa for lanes and paths. This provision, equal to one-{491}twenty-fifth of a surveyed area, was later on found to have an important bearing when comparing the total acreage of the Roman and Domesday surveys of the county, for the latter did not include road surface. A side of this square centuria measured 120 Roman poles or 388 yards, and five of them lining the face of a possessa accounted for those five successive equal intervals formed by crossways which were noticed upon a Middlesex road between Greenford and Ealing as above mentioned."

On Ancient Chinese Towns

Khanbaliq or Dadu  refers to a city which is the core of Beijing.   Dadu or Ta-Tu (大都, pinyin: Dàdū, Wade-Giles: Ta-tu), means "great capital" or "grand capital" in Chinese, the name for the capital of the Yuan Dynasty founded by Kublai Khan in China, and was called Daidu by the Mongols, which was a transliteration directly from the Chinese. It is known as Khanbaliq (汗八里), also spelled as Khanbalikh in Turkic languages, meaning "Great residence of the Khan", and Marco Polo wrote of it as Cambaluc.

Nosce te ipsum

"Il Gnôr Grassiadiô e il Gnôr Côlômbô erano due amici-nemici che, secondo la leggenda, abitarono per tempo immemorabile a fronte a fronte, sui due lati di uno stretto vicolo della città di Moncalvo. Il Gnôr Grassiadiô era massone e ricchissimo: si vergognava un poco di essere ebreo, ed aveva sposato una gôià, e cioè una cristiana, dai capelli biondi lunghi fino al suolo, che gli metteva le corna. Questa gôià, benché appunto gôià, si chiamava Magna Ausilia, il che indica un certo grado di accettazione da parte degli epigoni; era figlia di un capitano di mare, che aveva regalato al Gnôr Grassiadiô un grosso pappagallo di tutti i colori che veniva dalle Guyane, e diceva in latino "Conosci te stesso". Il Gnôr Côlômbò era povero e mazziniano: quando arrivò il pappagallo, si era comperata una cornacchia tutta spelacchiata e le aveva insegnato a parlare. Quando il pappagallo diceva "Nosce te ipsum" la cornacchia rispondeva "Fate furb", "fatti furbo"."

Gnôr Grassiadiô and Gnôr Côlômbô were two friendly enemies who, according to the legend, had lived from time immemorial face to face on the two sides of an alleyway in the town of Moncalvo. Gnôr Grassiadiô was a Mason and very rich. He was a bit ashamed of being a Jew and had married a goyà, that is, a Christian, with blond hair so long it touched the ground, who cuckolded him. This goyà, although really a goyà, was called Magna Ausilia, which indicates a certain degree of acceptance on the part of the epigones; she was the daughter of a sea captain who had presented Gnôr Grassiadiô with a large, varicolored parrot which came from Guyana and would say in Latin, “Know thyself.” Gnôr Côlômbô was poor and a Mazzinian. When the parrot arrived he bought a crow without a feather on its back and taught it to speak. When the parrot croaked, “Nosce te ipsum,” the crow answered, “Wise up.“

The Remarkable Properties of Mythological Social Networks | MIT Technology Review

"Today,  P J Miranda at the Federal Technological University of Paraná in Brazil and a couple of pals study the social network between characters in Homer’s ancient Greek poem, the Odyssey. Their conclusion is that this social network bears remarkable similarities to Facebook, Twitter and the like and that this may offer an important clue about the origin of this ancient story."
