ΑΒΑΞ

LEXARITHMOS 64

The abacus (ἄβαξ) as the ancient calculating tool, a precursor to the modern computer, used for arithmetic operations and games. Its lexarithmos (64) is mathematically linked to its square form and the order represented by the logic of numbers.

Definition

According to the Liddell-Scott-Jones Lexicon, ἄβαξ originally denotes "a board, a table, a slab." The term encompasses a wide range of flat surfaces utilized for various purposes in ancient Greece. Its most prominent application was as a computational device, a type of abacus, where numbers were represented by pebbles or counters moved along grooves or columns. This function establishes it as a fundamental instrument for the development of arithmetic and mathematical thought.

Beyond its arithmetical utility, the ἄβαξ also served as a board for games, such as draughts or other board games, where players manipulated pieces on a grid. Furthermore, it could be a tablet upon which geometric figures were drawn with sand or dust, enabling mathematicians to visualize and prove theorems. This versatility underscores its central role in both education and recreation within the ancient world.

In architecture, ἄβαξ referred to the square slab forming the uppermost part of a column's capital, upon which the architrave rested. This meaning highlights the word's capacity to describe stable, flat surfaces that bear weight or constitute a structural element. The diverse applications of the ἄβαξ reflect the practical ingenuity of the ancient Greeks and their ability to adapt a basic object to multiple needs.

Etymology

ἄβαξ ← Ancient Greek root belonging to the oldest stratum of the language
The etymology of ἄβαξ is considered Ancient Greek, belonging to the oldest stratum of the language. Its root suggests a "flat surface" or "board," from which its various meanings as a calculating board, game board, or architectural element emerged. The word does not exhibit direct cognates with other major Greek roots, indicating an autonomous development within the Greek lexicon.

Cognate words within the Greek language include the diminutives ἀβακίσκος and ἀβάκιον, as well as the adjective ἀβακωτός, which describes something "checkered" or "tessellated," like a board. The verb ἀβακίζω and the noun ἀβακισμός developed later to describe the act of calculating with the abacus.

Main Meanings

  1. Calculating board, abacus — The most prevalent meaning, as a tool for arithmetic operations using pebbles or counters.
  2. Game board, draughtboard — A surface for board games, where pieces were moved.
  3. Drawing board, sand-tray — A flat surface, often covered with sand or dust, used for geometric drawings and calculations.
  4. Table, sideboard — A type of table or side-table for placing objects, particularly in domestic use.
  5. Architectural element, column capital slab — The square slab at the top of a column, supporting the architrave.
  6. Writing tablet, slate — A board or slab used for writing or drawing.
  7. Plate, dish — Less commonly, referring to a flat vessel for food or offerings.

Philosophical Journey

The ἄβαξ, as a simple yet versatile tool, possesses a long history of use extending from ancient Greece through the Roman and Byzantine eras, adapting to various daily and scientific needs.

5th-4th C. BCE
Classical Greek Period
The ἄβαξ is widely used as a calculating and game board. Herodotus (2.36) mentions its use by Egyptians, while Plato (Lysis 209a) and Demosthenes (On the Crown 257) confirm its use in Greece for arithmetic operations.
3rd C. BCE
Hellenistic Period
Mathematicians such as Archimedes and Euclid, though not directly referring to the ἄβαξ as a tool for their theorems, its existence implies a context where arithmetic calculations were feasible and taught.
1st C. BCE - 2nd C. CE
Roman Period
The word is adopted into Latin as "abacus," and the tool continues to be extensively used for calculations, particularly in commercial transactions and public finance.
4th-6th C. CE
Late Antiquity
The ἄβαξ remains in use, with references in texts describing the education and practices of accountants. Its use persists as a basic arithmetic tool.
7th-12th C. CE
Byzantine Period
Although its use may have diminished with the development of other methods, the ἄβαξ is still mentioned in some Byzantine texts, primarily in relation to education and the history of mathematics.

In Ancient Texts

The ἄβαξ, as an everyday tool, is mentioned in various ancient texts, underscoring its practical significance.

«καὶ γράμμασι μὲν χρέωνται τοῖσι Ἑλληνικοῖσι, ἀπὸ δεξιῶν ἐπ' ἀριστερὰ γράφοντες· λογίζονται δὲ ψήφοισι ἀπ' ἀριστερῶν ἐπὶ δεξιὰ κινοῦντες.»
«And they use Greek letters, writing from right to left; but they reckon with pebbles, moving them from left to right.»
Herodotus, Histories 2.36
«οὐ γὰρ ἀριθμητικῆς οὐδὲ γεωμετρίας οὐδὲ ἀστρονομίας οὐδὲ ἀβάκων ἐστὶν ἡ μάθησις.»
«For it is not the learning of arithmetic nor of geometry nor of astronomy nor of abaci.»
Plato, Lysis 209a
«οὐδὲ γὰρ ἄβακα οὐδὲ ψήφους ἔχων ἐλογίζετο.»
«For he did not calculate having either an abacus or pebbles.»
Demosthenes, On the Crown 257

ἀλήθεια
«truth, reality.» A fundamental philosophical concept, which, like the ἄβαξ, seeks the revelation of order, but in the realm of ideas rather than numbers.
γενεά
«birth, generation, race.» Connected to origin and succession, in contrast to the ἄβαξ which deals with the quantitative measurement of the present.
Δανάη
The name of Perseus' mother in mythology. The connection here is purely numerical, without conceptual kinship to the ἄβαξ.
