s which may include short rongorongo inscriptions. Oral history suggests that only a small elite was ever literate and that the tablets were sacred. Authentic rongorongo texts are written in alternating directions, a system called reverse boustrophedon. In a third of the tablets, the lines of text are inscribed in shallow fluting carved into the wood. The glyphs themselves are outlines of human, animal, plant, artifact and geometric forms. Many of the human and animal figures, such as glyphs and have characteristic protuberances on each side of the head, possibly representing eyes. Individual texts are conventionally known by a single uppercase letter and a name, such as Tablet C, the ''Mamari'' Tablet. The (somewhat variable) names may be descriptive or indicate where the object is kept, as in the Oar, the Snuffbox, the Small Santiago Tablet, and the Santiago Staff.


Etymology and variant names

''Rongorongo'' is the modern name for the inscriptions. In the
Rapa Nui language Rapa Nui or Rapanui (, Rapa Nui: , Spanish: ), also known as Pascuan () or ''Pascuense'', is an Eastern Polynesian language of the Austronesian language family. It is spoken on Easter Island, also known as ''Rapa Nui''. The island is home to ...
, or means "to recite, to declaim, to chant out". The original name—or perhaps description—of the script is said to have been , "lines incised for chanting out", shortened to or "lines orchanting out".Englert 1993 There are also said to have been more specific names for the texts based on their topic. For example, the ("lines of years") were annals, the ("lines of fishes") were lists of persons killed in war ( "fish" was homophonous with or used figuratively for "war casualty"), and the "lines of fugitives" were lists of war refugees. Some authors have understood the in to refer to a separate form of writing distinct from . Barthel recorded that "The Islanders had another writing (the so-called ' script') which recorded their annals and other secular matters, but this has disappeared." But

writes that "the was originally a type of inscription. In the 1880s, a group of elders invented a derivative 'script' lsocalled with which to decorate carvings in order to increase their trading value. It is a primitive imitation of ." An alleged third script, the or described in some mid-20th-century publications, was "an early twentieth-century geometric ecorativeinvention".


Form and construction

The forms of the glyphs are standardized contours of living organisms and geometric designs about one centimeter high. The wooden tablets are irregular in shape and, in many instances, fluted (tablets B, E, G, H, O, Q, and possibly T), with the glyphs carved in shallow channels running the length of the tablets, as can be seen in the image of tablet G at right. It is thought that irregular and often blemished pieces of wood were used in their entirety rather than squared off due to the scarcity of wood on the island.


Writing media

Except for a few possible glyphs cut in stone (see

assembled from sections cut from a rongorongo tablet. The tablets, like the pectorals, statuettes, and staves, were works of art and valued possessions, and were apparently given individual proper names in the same manner as jade ornaments in New Zealand. Two of the tablets, C and S, have a documented pre-missionary provenance, though others may be as old or older. There are in addition a few isolated glyphs or short sequences which might prove to be rongorongo.


Classic texts

Barthel referred to each of 24 texts he accepted as genuine with a letter of the alphabet; two texts have been added to the corpus since then. The two faces of the tablets are distinguished by suffixing r (

) when the reading sequence can be ascertained, to which the line being discussed is appended. Thus Pr2 is item P (the Great Saint Petersburg Tablet), recto, second line. When the reading sequence cannot be ascertained, a and b are used for the faces. Thus Ab1 is item A ''(Tahua),'' side b, first line. The six sides of the Snuff Box are lettered as sides a to f. Nearly all publications follow the Barthel convention, though a popular book by Fischer uses an idiosyncratic numbering system. Crude glyphs have been found on a few stone objects and some additional wooden items, but most of these are thought to be fakes created for the early tourism market. Several of the 26 wooden texts are suspect due to uncertain provenance (X, Y, and Z), poor quality craftsmanship (F, K, V, W, Y, and Z), or to having been carved with a steel blade (K, V, and Y), and thus, although they may prove to be genuine, should not be trusted in initial attempts at decipherment. Z resembles many early forgeries in not being boustrophedon, but it may be a

on an authentic but now illegible text.


Additional texts

In addition to the petroglyphs mentioned above, there are a few other very short uncatalogued texts that may be rongorongo. Fischer reports that "many statuettes reveal or -like glyphs on their crown." He gives the example of a compound glyph, , on the crown of a statuette. Many human skulls are inscribed with the single 'fish' glyph 700 , which may stand for "war casualty". There are other designs, including some tattoos recorded by early visitors, which are possibly single rongorongo glyphs, but since they are isolated and pictographic, it is difficult to know whether or not they are actually writing. In 2018, a possibly authentic ink-on-

sequence dating from 1869, dubbed the " Raŋitoki fragment", was recognized.


Glyphs

The only published reference to the glyphs which is even close to comprehensive remains Barthel (1958). Barthel assigned a three-digit numeric code to each glyph or to each group of similar-looking glyphs that he believed to be

s (variants). In the case of allography, the bare numeric code was assigned to what Barthel believed to be the basic form (''Grundtypus''), while variants were specified by alphabetic suffixes. Altogether he assigned 600 numeric codes. The hundreds place is a digit from 0 to 7, and categorizes the head, or overall form if there is no head: 0 and 1 for geometric shapes and inanimate objects; 2 for figures with "ears"; 3 and 4 for figures with open mouths (they are differentiated by their legs/tails); 5 for figures with miscellaneous heads; 6 for figures with beaks; and 7 for fish, arthropods, etc. The digits in tens and units places were allocated similarly, so that, for example, glyphs 206, 306, 406, 506, and 606 all have a downward-pointing wing or arm on the left, and a raised four-fingered hand on the right: There is some arbitrariness to which glyphs are grouped together, and there are inconsistencies in the assignments of numerical codes and the use of affixes which make the system rather complex. However, despite its shortcomings, Barthel's is the only effective system ever proposed to categorize rongorongo glyphs. Barthel (1971) claimed to have parsed the corpus of glyphs to 120, of which the other 480 in his inventory are allographs or

. The evidence was never published, but similar counts have been obtained by other scholars, such as Pozdniakov & Pozdniakov (2007).


Published corpus

For almost a century only a few of the texts were published. In 1875, the director of the

, Rudolf Philippi, published the Santiago Staff, and Carroll (1892) published part of the Oar. Most texts remained beyond the reach of would-be decipherers until 1958, when Thomas Barthel published line drawings of almost all the known corpus in his ("Bases for the Decipherment of the Easter Island script") which remains the fundamental reference to rongorongo. He transcribed texts A through X, over 99% of the corpus; the

s, which helped ensure their faithfulness to the originals. Fischer (1997) published new line drawings. These include lines scored with obsidian but not finished with a shark tooth, which had not been recorded by Barthel because the rubbings he used often did not show them, for example on tablet N. (However, in line Gv4 shown in the section on

above, the light lines were recorded by both Fischer and Barthel.) There are other omissions in Barthel which Fischer corrects, such as a sequence of glyphs at the transition from line Ca6 to Ca7 which is missing from Barthel, presumably because the carving went over the side of the tablet and was missed by Barthel's rubbing. (This missing sequence is right in the middle of Barthel's calendar.) However, other discrepancies between the two records are straightforward contradictions. For instance, the initial glyph of I12 (line 12 of the Santiago Staff) in Fischer does not correspond with that of Barthel or Philippi, which agree with each other, and Barthel's rubbing (below) is incompatible with Fischer's drawing. Barthel's annotation, ''Original doch 53.76!'' ("original indeed 53.76!"), suggests that he specifically verified Philippi's reading: In addition, the next glyph (glyph 20, a "spindle with three knobs") is missing its right-side "sprout" (glyph 10) in Philippi's drawing. This may be the result of an error in the inking, since there is a blank space in its place. The corpus is thus tainted with quite some uncertainty. It has never been properly checked for want of high-quality photographs.


Decipherment

As with most undeciphered scripts, there are many fanciful interpretations and claimed translations of rongorongo. However, apart from a portion of one tablet which has been shown to have to do with a lunar
Rapa Nui calendar The Rapa Nui calendar was the indigenous lunisolar calendar of Easter Island. It is now obsolete. Attestation William J. Thomson, paymaster on the USS ''Mohican'', spent twelve days on Easter Island from December 19 to 30, 1886. Among the data ...
and a possible genealogy, none of the texts are understood. There are three serious obstacles to decipherment, assuming rongorongo is truly writing: the small number of remaining texts, the lack of context such as illustrations in which to interpret them, and the poor attestation of the Old Rapa Nui language, since modern

device for genealogy, choreography, navigation, astronomy, or agriculture. For example, the ''Atlas of Languages'' states, "It was probably used as a memory aid or for decorative purposes, not for recording the Rapanui language of the islanders." If this is the case, then there is little hope of ever deciphering it. For those who believe it to be writing, there is debate as to whether rongorongo is essentially
