/tsade (Ϻ, denoting an [s] sound), was not used in this way. Instead, sampi was chosen, and added at the end of the system, after omega (800).

From this, it has been concluded that the system must have been invented at a time and place when digamma and koppa were still either in use or at least still remembered as parts of the alphabetic sequence, whereas san had either already been forgotten, or at least was no longer remembered with its original alphabetic position. In the latter case, according to a much debated view, sampi itself may in fact have been regarded as being san, but with a new position in the alphabet.

The dating of the emergence of this system, and with it of numeric sampi, has been the object of much discussion. At the end of the 19th century, authors such as Thompson placed its full development only in the 3rd century BC. Jeffery states that the system as a whole can be traced much further back, into the 6th century BC. An early, though isolated, instance of apparent use of alphabetic Milesian numerals in Athens occurs on a stone inscribed with several columns of two-digit numerals, of unknown meaning, dated from the middle of the 5th century BC.

While the emergence of the system as a whole has thus been given a much earlier dating than was often assumed earlier, actual occurrences of the letter sampi in this context have as yet not been found in any early examples. According to Threatte, the earliest known use of numeric sampi in a stone inscription occurs in an inscription in Magnesia
Magnesia on the Maeander

 from the 2nd century BC, in a phrase denoting a sum of money (") but the exact numeric meaning of this example is disputed. In Athens, the first attestation is only from the beginning of the 2nd century AD, again in an inscription naming sums of money.

Earlier than the attestations in the full function as a numeral are a few instances where sampi was used in Athens as a mark to enumerate sequences of things in a set, along with the 24 other letters of the alphabet, without implying a specific decimal numeral value. For instance, there is a set of 25 metal tokens, each stamped with one of the letters from alpha to sampi, which are dated to the 4th century BC and were probably used as identification marks for judges in the courts of the Athenean democracy.

 period onwards, numeric sampi occurs with some regularity.

At an early stage in the papyri, the numeral sampi was used not only for 900, but, somewhat confusingly, also as a multiplicator for 1000, since a way of marking thousands and their multiples was not yet otherwise provided by the alphabetic system. Writing an alpha over sampi ( or, in a ligature) meant "1×1000", a theta over sampi meant "9×1000", and so on. In the examples cited by Gardthausen, a slightly modified shape of sampi, with a shorter right stem , is used. This system was later simplified into one where the thousands operator was marked just as a small stroke to the left of the letter (͵α = 1000).

In early stone inscriptions, the shape of sampi, both alphabetic and numeric, is . Square-topped shapes, with the middle vertical stroke either of equal length with the outer ones or longer , are also found in early papyri.

, Galen says that one of them "looks like the way some people write the sign for 900", and describes this as "the shape of the letter Π with a vertical line in the middle" ("").
From the time of the earliest papyri, the square-topped forms of handwritten sampi alternate with variants where the top is rounded () or pointed (). The rounded form also occurs in stone inscriptions in the Roman era. In the late Roman period, the arrow-shaped or rounded forms are often written with a loop connecting the two lines at the right, leading to the "ace-of-spades" form , or to . These forms, in turn, occasionally have another decorative stroke added on the left . It can be found attached in several different ways, from the top or the bottom . From these shapes, finally, the modern form of sampi emerges, beginning in the 9th century, with the two straight lines becoming more or less parallel (, ).

In medieval western manuscripts describing the Greek alphabet, the arrowhead form is sometimes rendered as .

Origins

Throughout the 19th and 20th centuries, many authors have assumed that sampi was essentially a historical continuation of the archaic letter san
San (letter)
San was an archaic letter of the Greek alphabet. Its shape was similar to modern M, or to a modern Greek Sigma turned sideways, and it was used as an alternative to Sigma to denote the sound . Unlike Sigma, whose position in the alphabet is between Rho and Tau, San appeared between Pi and Qoppa...

(Π) and koppa (Ϙ). It dropped out of use in favour of sigma in most dialects by the 7th century BC, but was retained in place of the latter in a number of local alphabets until the 5th century BC. It is generally agreed to be derived from Phoenician tsade.

The hypothetical identification between san and sampi is based on a number of considerations. One is the similarity of the sounds represented by both. san represented either simple [s] or some other, divergent phonetic realization of the common Greek /s/ phoneme. Suggestions for its original sound value have included [ts], [z], and [ʃ]. The second reason for the assumption is the sytematicity in the development of the letter inventory: there were three archaic letters that dropped out of use in alphabetic writing (digamma/wau
Digamma
Digamma is an archaic letter of the Greek alphabet which originally stood for the sound /w/ and later remained in use only as a numeral symbol for the number "6"...

, koppa, and san), and three extra-alphabetic letters were adopted for the Milesian numeral system, two of them obviously identical with the archaic digamma and koppa; hence, it is easy to assume that the third in the set had the same history. Objections to this account have been related to the fact that sampi did not assume the same position san had had, and to the lack of any obvious relation between the shapes of the two letters and the lack of any intermediate forms linking the two uses.

Among older authorities, Gardthausen and Thompson took the identity between san and sampi for granted. Foat, in a skeptical reassessment of the evidence, came to the conclusion that it was a plausible hypothesis but unprovable. The discussion has continued until the present, while a steady trickle of new archaeological discoveries regarding the relative dating of the various events involved (i.e. the original emergence of the alphabet, the loss of archaic san, the emergence of alphabetic sampi, and the emergence of the numeral system) have continued to affect the data base on which it is founded.

A part of the discussion about the identity of san and sampi has revolved around a difficult and probably corrupted piece of philological commentary by an anonymous scholiast

Scaliger's discussion also contains the first known attestation of the name "san pi" (sampi) in the western literature, and the first attempt at explaining it.

 mark on each: "koppa" and "san" respectively. After explaining this, the anonymous scholiast adds a digression that appears to be meant to further explain the name and function of "san", drawing some kind of link between it and the numeral sign of 900. However, what exactly was meant here is obscure now, because the text was evidently corrupted during transmission and the actual symbols cited in it were probably exchanged. The following is the passage in the reading provided by a modern edition, with problematic words marked:
There is still no agreement on what was originally meant by this passage. While Scaliger in the 17th century believed that the scholiast spoke of san as a synonym for sigma, and meant to describe the (modern) shape of sampi (ϡ) as being composed of an inverted lunate sigma and a π, the modern editor D. Holwerda believes the scholiast spoke of the actual M-shaped san and expressed a belief that modern sampi was related to it.

An alternative hypothesis to that of the historical identity between san and sampi is that Ionian sampi may have been a loan from the neighbouring Anatolian
Anatolian languages
The Anatolian languages comprise a group of extinct Indo-European languages that were spoken in Asia Minor, the best attested of them being the Hittite language.-Origins:...

 language Carian, which formed the local substrate in the Ionian colonies of Asia Minor. This hypothesis is mentioned by Jeffery and has been supported more recently by Genzardi
Brixhe suggested that sampi could be related to the Carian letter 25 "", transcribed as ś. This would fit in with the "plausible, but not provable" hypothesis that the root contained in the Carian-Greek names spelled with sampi, "Πανυασσις" and "Οασσασσις", is identical with a root *uś-/waś- identified elsewhere in Carian, which contains the Carian ś sound spelled with . Adiego follows this with the hypothesis that both the Carian letter and sampi could ultimately go back to Greek Ζ . Like the san–sampi hypothesis, the Carian hypothesis remains an open and controversial issue, especially since the knowledge of Carian itself is still fragmentary and developing.

While the origin of sampi continues to be debated, the identity between the alphabetic Ionian sampi (/ss/) and the numeral for 900 has rarely been in doubt, although in the older literature it was sometimes mentioned only tentatively, An isolated position was expressed in the early 20th century by Jannaris, who – without mentioning the alphabetic use of Ionian /ss/ – proposed that the shape of numeric sampi was derived from a juxtaposition of three "T"s, i.e. 3×300=900. (He also rejected the historical identity of the other two numerals, stigma

 (6) and koppa (90), with their apparent alphabetic predecessors.) Today, the link between alphabetic and numeral sampi is universally accepted.

Names

Despite all uncertainties, authors who subscribe to the hypothesis of a historical link between ancient san and sampi also often continue to use the name san for the latter. Benedict Einarson hypothesizes that it was in fact called *ssan, with the special quality of the sibilant sound it had as Ionian This opinion has been rejected as phonologically impossible by Soldati, who points out that the /ss/ sound only ever occurred in the middle of words and therefore could not have been used in the beginning of its own name.

As for the name sampi itself, it is generally agreed today that it is of late origin and not the original name of the character in either its ancient alphabetic or its numeral function. Babiniotis describes it as "medieval", while Jannaris places its emergence "after the thirteenth century". However, the precise time of its emergence in Greek is not documented.

The name is already attested in manuscript copies of an Old Church Slavonic

 and later transmitted in the Cyrillic script. In one medieval Cyrillic group of manuscripts of this text, probably going back to a marginal note in an earlier Glagolitic version, the letter names "sampi" ("") and "koppa" ("") are used for the Greek numerals. Witnesses of this textual variant exist from c.1200, but its archetype can be dated to before 1000 AD.

The first reference to the name sampi in the western literature occurs in a 17th-century work, Scaliger's discussion of the Aristophanes scholion regarding the word samphoras (see above). Some modern authors, taking Scaliger's reference as the first known use and unaware of earlier attestations, have claimed that the name itself only originated in the 17th century and/or that Scaliger himself invented it. A related term was used shortly after Scaliger by the French author Montfaucon, who called the sign "" (antisigma-pi), "because the Greeks regarded it as being composed of an inverted sigma, which is called , and from " ("Graeci putarunt ex inverso sigma, quod vocatur, et ex compositum esse").

The etymology of sampi has given rise to much speculation. The only element all authors agree on is that the -pi refers to the letter π, but about the rest accounts differ depending on each author's stance on the question of the historical identity between sampi and san.

According to the original suggestion by Scaliger, san-pi means "written like a san and a pi together". Here, "san" refers not to the archaic letter san (i.e. Ϻ) itself, but to "san" as a mere synonym of "sigma", referring to the outer curve of the modern ϡ as resembling an inverted lunate sigma. This reading is problematic because it fits the shape only of the modern (late Byzantine) sampi but presupposes active use of an archaic nomenclature that had long since lost currency by the time that shape emerged. According to a second hypothesis, san-pi would originally have meant "the san that stands next to pi in the alphabet". This proposal thus presupposes the historical identity between sampi and ancient san (Ϻ), which indeed stood behind Π. However, this account too is problematic as it implies a very early date of the emergence of the name, since after the archaic period the original position of san was apparently no longer remembered, and the whole point of the use of sampi in the numeral system is that it stands somewhere else. Yet a different hypothesis interprets san-pi in the sense of "the san that resembles pi". This is usually taken as referring to the modern ϡ shape, presupposing that the name san alone had persisted from antiquity until the time the sign took that modern shape. None of these hypotheses has wide support today. The most commonly accepted explanation of the name today is that san pi simply means "like a pi", where the word san is unrelated to any letter name but simply the modern Greek preposition ("like", from ancient Greek ).

In the absence of a proper name, there are indications that various generic terms were used in Byzantine times to refer to the sign. Thus, the 15th-century Greek mathematician Nikolaos Rabdas referred to the three numerals for 6, 90 and 900 as "τὸ ἐπίσημον", "τὸ ἀνώνυμον σημεῖον" ("the nameless sign", i.e. koppa), and "ὁ καλούμενος χαρακτήρ" ("the so-called charaktir", i.e. just "the character"), respectively. The term "ἐπίσημον" (episēmon, literally "outstanding") is today used properly as a generic cover term for all three extra-alphabetic numeral signs, but was used specifically to refer to 6 (i.e. digamma

).

In some early medieval Latin documents from western Europe, there are descriptions of the contemporary Greek numeral system which imply that sampi was known simply by the Greek word for its numeric value, ἐννεακόσια (enneakosia, "nine hundred"). Thus, in De loquela per gestum digitorum, a didactic text about arithmetics attributed to the Venerable Bede, the three Greek numerals for 6, 90 and 900 are called "episimon", "cophe" and "enneacosis" respectively. the latter two being evidently corrupted versions of koppa and enneakosia. An anonymous 9th-century manuscript from Rheinau Abbey

 has epistmon [sic], kophe, and ennakose. Similarly, the Psalterium Cusanum, a 9th or 10th century bilingual Greek—Latin manuscript, has episimôn, enacôse and cophê respectively (with the latter two names mistakenly interchanged for each other.) Another medieval manuscript has the same words distorted somewhat more, as psima, coppo and enacos, Other, similar versions of the name include enacosin and niacusin, or the curious corruption sincope,

A curious name for sampi that occurs in one Greek source is "παρακύϊσμα" (parakyisma). It occurs in a scholion to Dionysius Thrax
Dionysius Thrax

, where the three numerals are referred to as "τὸ δίγαμμα καὶ τὸ κόππα καὶ τό καλούμενον παρακύϊσμα". The obscure word ("… the so-called parakyisma") literally means "a spurious pregnancy", from "παρα-" and the verb "κυέω" "to be pregnant". The term has been used and accepted as possibly authentic by Jannaris, Uhlhorn and again by Soldati. While Jannaris hypothesizes that it was meant to evoke the oblique, reclining shape of the character, Soldati suggests it was meant to evoke its status as an irregular, out-of-place addition ("un'utile superfetazione"). Einarson, however, argues that the word is probably the product of textual corruption during transmission in the Byzantine period. He suggests that the original reading was similar to that used by Rabdas, "ὁ καλούμενος χαρακτήρ" ("the so-called character"). Another contemporary cover term for the extra-alphabetic numerals would have been "παράσημον" (parasēmon, lit. "extra sign"). A redactor could have written the consonant letters "π-σ-μ" of "παράσημον" over the letters "χ-κτ-ρ" of "χαρακτήρ", as both words happen to share their remaining intermediate letters. The result, mixed together from letters of both words, could have been misread in the next step as "παρακυησμ", and hence, "παρακύϊσμα".

An entirely new proposal has been made by A. Willi, who suggests that the original name of the letter in ancient Greek was angma . This proposal is based on a passage in a Latin grammarian, Varro
Varro
Varro was a Roman cognomen carried by:*Marcus Terentius Varro, sometimes known as Varro Reatinus, the scholar*Publius Terentius Varro or Varro Atacinus, the poet*Gaius Terentius Varro, the consul defeated at the battle of Cannae...

, who uses this name for what he calls a "25th letter" of the alphabet. Varro himself is clearly not referring to sampi, but is using angma to refer to the ng sound ŋ in words like angelus. However, Varro ascribes the use of the name angma to an ancient Ionian Greek author, Ion of Chios
Ion of Chios
Ion of Chios was a Greek writer, dramatist, lyric poet and philosopher. He was a contemporary of Aeschylus, Euripides and Sophocles. Of his many plays and poems only a few titles and fragments have survived...

. Willi conjectures that Varro misunderstood Ion, believing the name angma referred to the [ŋ] sound because that sound happened to occur in the name itself. However, Ion, in speaking of a "25th letter of the alphabet", meant not just a different pronunciation of some other letters but an actual written letter in its own right, namely sampi. According to Willi's hypothesis, the name angma would have been derived from the verbal root *ank-, "to bend, curve", and referred to a "crooked object", used because of the hook-like shape of the letter.

According to a numismatic website, the term disigma was used for the epigraphic character by some late 19th and early 20th century authors. This usage is currently not found in the literature.

Modern use

Together with the other elements of the Greek numeral system, sampi is occasionally still used in Greek today. However, since the system is typically used only to enumerate items in relatively small sets, such as the chapters of a book or the names of rulers in a dynasty, the signs for the higher tens and hundreds, including sampi, are much less frequently found in practice than the lower letters for 1 to 10. One of the few domains where higher numbers including thousands and hundreds are still expressed in the old system in Greece with some regularity is the field of law, because until 1914 laws were numbered in this way. For instance, one law which happens to have sampi in its name and is still in force and relatively often referred to is "Νόμος ͵ΓϠΝʹ/1911" (i.e. Law Number 3950 of 1911), "Περί της εκ των αυτοκινήτων ποινικής και αστικής ευθύνης" ("About penal and civil responsibility arising from the use of automobiles"). However, in informal practice, the letter sampi is often replaced in such instances by a lowercase or uppercase π.

 character encoding standard, experimental typographical stylizations of a lowercase textual Sampi have been developed. The Unicode reference glyph for "small letter archaic sampi", according to an original draft, was to have looked like the stem of a small τ with a square top at x height, but was changed after consultation with Greek typesetting experts. The glyph shown in current official code charts stands on the baseline

Computer encoding

Several codepoints for the encoding of sampi and its variants have been included in Unicode

. As they were adopted successively in different versions of Unicode, their coverage in current computer fonts and operating systems is inconsistent as of 2010. U+03E0 ("Greek letter Sampi") was present from version 1.1 (1993) and was originally meant to show the normal modern numeral glyph. The uppercase/lowercase contrast was introduced with version 3.0 (1999). As the existing code point had been technically defined as an uppercase character, the new addition was declared lowercase (U+03E1, "Greek small letter Sampi"). This has led to some inconsistency between fonts, because the glyph that was present at U+03E0 in older fonts is now usually found at U+03E1 in newer ones, while U+03E0 may have a typographically uncommon capital glyph.

New, separate codepoints for ancient epigraphic sampi, also in an uppercase and lowercase variant, were proposed in 2005, and included in the standard with version 5.1 (2008). They are meant to cover both the Ionian and Pamphylian , with the Ionian character serving as the reference glyph. As of 2010, these characters are not yet supported by most current Greek fonts. The Gothic "900" symbol was encoded in version 3.1 (2001), and Coptic sampi in version 4.1 (2005). Codepoints for the related Greek characters san and Bactrian "sho

Prior to Unicode, support for sampi in electronic encoding was marginal. No common 8-bit codepage for Greek (such as ISO 8859-7) contained sampi. However, lowercase and uppercase sampi were provided for by the ISO 5428:1984 Greek alphabet coded character set for bibliographic information interchange. In Beta code
