_Ptolemy’s Map of Ireland – Part 10_ ~ [Part 1](https://steemit.com/ireland/@harlotscurse/ptolemy-s-map-of-ireland-part-1)~ https://i.imgur.com/qvcLw4T.jpg**Part of Ptolemy’s Map of Ireland (Nicholaus Germanus)** Claudius Ptolemy’s description of Ireland in his [_Geography_](https://en.wikipedia.org/wiki/Geography_(Ptolemy)) comprises a list of sixty items, forty of which are accompanied by latitudes and longitudes. In this article, I begin my study of these items in an attempt to identify them one by one. I am setting out from the south-east corner of the island and proceeding counterclockwise, before moving inland. Traders and explorers coming to Ireland from the continent or from southern Britain would probably have made their first landfall somewhere along this stretch of coast, and they were more likely to have explored the eastern side of the island before venturing west into the Atlantic Ocean. # _Sacrum Promontorium_ # There is another reason for beginning in the south-east corner of the island: the promontory or headland which Ptolemy places at this point is one of the least controversial items in his list. Throughout the ages, scholars have been almost unanimous in identifying Ptolemy’s _ἱερον ἀκρον_ with Carnsore Point in the south-east corner of Ireland. The only controversy has concerned the meaning and origin of the name—of which more later. https://i.imgur.com/MGNrjSg.jpg**Carnsore Point from the Air** The principal sources are all in agreement in locating this landmark in longitude 14°, but there is a discrepancy of 20' of arc in the latitude. Müller (57° 50') follows the Vat Gr 191 manuscript, which is thought to be closest to Ptolemy’s lost autograph, while Wilberg and Nobbe (57° 30') follow most of the other sources. At least one manuscript places this promontory in latitude 58° (Orpen 120). Ptolemy is believed to have indicated 30' of arc, or half a degree, with the symbol , or something like it, which signified one half. To indicate 50' of arc, he added to this the letter Γ (gamma). Gamma normally represented the number 3, but in this context it stood for the fraction 1/3. 50' is one half of a degree plus one third of a degree. It is possible that Ptolemy’s gamma was simply omitted by an early copyist, corrupting 50' to 30'. This is more likely than the addition of a extraneous gamma that was not in Ptolemy’s autograph. In several manuscripts, the previous item in Ptolemy’s list has a latitude of 57° 30'.

All extant manuscripts record it as ἱερὸν ἄκρον (_Hieron Akron_), with only minor diacritical differences between them. Ptolemy’s use of diacritics is unknown. The practice of adding primes to letters to indicate, for example, that they represent fractions rather than the usual integers was only regularized much later. In a recent study, Alexander Jones simply omits them: >I omit diacritical marks distinguishing whole numbers from fractions, since in my experience the testimony of manuscripts is practically worthless with respect to them. (Jones 42 n 27) Alexander Jones is currently Professor of the History of the Exact Sciences in Antiquity for the Institute for the Study of the Ancient World at New York University. Amalia Gnanadesikan is the Technical Director for Language Analysis at the University of Maryland’s Center for Advanced Study of Language. In her book _The Writing Revolution_, she makes the following pertinent comment on the question of smooth and rough breathing in Ptolemy’s Alexandria: >In the process of accumulating and copying texts, the Alexandrian scholars began to show concern for matters of orthography. They found that at certain points the lack of a written form of [h] made for ambiguity. They noted that the Greeks living in Italy had been more free-thinking than the Athenians. While they had gone along with the adoption of the Ionic alphabet, they continued to write [h] by cutting the _hēta_ in half and using ├. The Alexandrians adopted the Italian Greeks’ half H, but wrote it as a superscript on the following vowel, so that, for example, https://i.imgur.com/ZHdwc4J.png**_ho_** >was _ho_. Loving symmetry, they made the other half of H stand for the _lack_ of an [h] sound before a vowel: https://i.imgur.com/xegclwj.png**_o_** >These diacritics came to be termed “rough breathing” (for [h]) and “smooth breathing” (for lack of [h]). Their use was for many centuries largely reserved for cases where ambiguity could arise without them. These marks later became **‘** and **’**, so that ὁ was _ho_ and ὀ plain _o_ ... Only by the ninth century AD (well into the Byzantine period, AD 330–1453) did the use of breathing and accent diacritics become fully regular, with all vowel-initial words marked for “rough” or “smooth” breathing and all words marked for accent. (Gnanadesikan 220 ... 221) I take these remarks to imply that Ptolemy probably only employed the diacritics for smooth and rough breathings in cases where the correct reading was not already obvious to the reader. This is the practice I intend to follow in this and subsequent articles. https://i.imgur.com/4VqpXkk.jpg**Hieron Akron in Vat Gr 191, Folium 139r (Boxed)** # _Hieron Akron_ # The literal translation of this Greek name is Sacred Headland, or Holy Head, which appears in Latin editions of the _Geography_ as _Sacrum Promontorium_. As it is wholly Greek, I chose to omit the breathings. The origin of this name, however, is anything but Greek. It was explained succinctly by O’Rahilly thus: >The name _’Ιέρνη_, “Ireland”, had probably been picked up by the [Massaliot Greeks](https://en.wikipedia.org/wiki/Marseille), from merchants and from their Celtic neighbours, as early as the fifth century B.C. ... Compare _gens Hiernorum_ in [Avienus](https://en.wikipedia.org/wiki/Avienus), implying _’Ιέρνοι_ in his Greek original. Owing to the loss of so much of the work of the early Greek geographers, _’Ιέρνη_ is not attested before Strabo (contemporary with Augustus). The [digamma](https://en.wikipedia.org/wiki/Digamma) had disappeared from Ionic as early as the seventh century B.C.; and when the Massaliot Greeks first heard the name _Īvernā_ [Ireland], they presumably had no means of indicating the _-v-_ and simply dropped it. Later the Greeks adopted the expedient of representing _v_ in foreign names by _ου_ ... Ptolemy, or some near predecessor of his, modernized _’Ιέρνη_ into _’Ιουερνία_ ... (O’Rahilly 41-42. See also 83.) So the original name of the south-eastern headland was Celtic and meant simply Cape Ireland, or Irish Head, or something of the sort. This was then corrupted to the Greek _Holy Head_. A similar corruption was also applied to the island as a whole by the Latin poet Avienus, as O’Rahilly again noted: >Avienus’s name for Ireland is _sacra insula_ [_Holy Isle_] (_Ora Maritima_ 108); presumably _’Ιέρνη νησος_ had been corrupted to _ἱερὰ νησος_ in the Greek text he had before him. (O’Rahilly 83 fn 6) Cape Ireland is an appropriate name for the first Irish landmark a foreign visitor would glimpse after crossing St George’s Channel. https://i.imgur.com/deqoMvA.jpg**On Carnsore Point** # Carnsore Point # Ireland’s south-eastern headland is now known as Carnsore Point, and there is little doubt that this is the headland Ptolemy is referring to. Curiously, though, scholars are not absolutely unanimous on this issue. Greenore Point, which lies 5 km northeast of Carnsore Point, and Hook Head, which lies about 20 km to the west of Carnsore Point in the same county—Wexford—have been favoured by a few: Carnsore Point|Greenore Point|Hook Head -|-|- -|-|[Camden (1607)](http://www.philological.bham.ac.uk/cambrit/irelandeng1.html#wex1) [Ware (1654)](http://www.askaboutireland.ie/reading-room/digital-book-collection/digital-books-by-subject/history-of-ireland/harris-the-whole-works-of/)|-|- -|-|[Lewis (1837)](http://www.askaboutireland.ie/reading-room/digital-book-collection/digital-books-by-subject/geography-of-ireland/lewis-a-topographical-dic/) Orpen (1894)|-|- -|[Martin (1910)](https://archive.org/stream/recordinterprete00martiala#page/282/mode/2up)|[Martin (1910)](https://archive.org/stream/recordinterprete00martiala#page/282/mode/2up) Mac an Bhaird (1991-93)|-|- Francis (1994)|-|- Bursche & Warner (2000)|-|- Darcy & Flynn (2008)|-|- **Source: Darcy & Flynn 57** The modern name of Carnsore Point combines the Irish word [_carn_](https://www.teanglann.ie/en/fgb/carn) with the old Norse [_eyrr_](https://en.wiktionary.org/wiki/eyrr). The latter signifies _a small tongue of land running into the sea_ (Walsh 28), or a gravel beach. The former refers to a cairn or megalithic tomb. There was once such a structure close to the headland, known locally as the Giant’s Grave. In the Short Chronology, this was a Celtic artifact and probably postdated Ptolemy’s principal source. The following description of this structure is adapted from the National Monuments Service’s [Historic Inventory Viewer](http://webgis.archaeology.ie/historicenvironment/?SMRS=WX053-035002-): >Located at the bottom of a slight south- and east-facing slope at Carnsore Point, and marked on the 1839 and 1940 editions of the Ordnance Survey 6-inch map, where it is described in gothic lettering as a Giant’s Grave and a Dolmen respectively. The earliest reference is from the _Dublin Magazine_ of August 1764, where it is described as 23ft [7 m] in length. The artist [Gabriel Beranger](https://en.wikipedia.org/wiki/Gabriel_Beranger) sketched it in 1780 (Wilde 129), although this has never been published. The area was excavated (E000142) in 1975, but a trench (20m x 5m) produced no evidence of the structure. It can be concluded that erosion by the sea has removed all trace of it (Cahill and Lynch 7, 59). The excavation in 1975 was carried out by [Michael J O’Kelly](https://en.wikipedia.org/wiki/Michael_J._O%27Kelly) on behalf of the Electricity Supply Board, which owned the surrounding land. A plan to construct a nuclear power plant on the site was famously thwarted by public protests in 1978. In 2003 a wind farm was opened on the site. https://i.imgur.com/noght6v.jpg**Carnsore Point Wind Farm** ## References ## * [Alexander Jones (editor)](https://books.google.com/books?id=Y61qolT7m98C), _Ptolemy in Perspective: Use and Criticism of his Work from Antiquity to the Nineteenth Century_, Springer, Dordrecht (2010) * [Amalia E Gnanadesikan](https://docslide.com.br/download/link/the-writing-revolution-cuneiform-to-the-internet-the-language-library), _The Writing Revolution: Cuneiform to the Internet_, Blackwell Publishing, John Wiley & Sons, Ltd, Chichester (2009) * [Michael J O’Kelly](http://catalogue.nli.ie/Record/vtls000088112), _Archaeological Survey and Excavation of St. Vogue’s Church, Enclosure and Other Monuments at Carnsore, Co.
