Communi, Decimum Saeculum (isopsephia)

From Kook Science

Communi, Decimum Saeculum (Tenth Century Common) is a system of converting Latin letters to defined numeric values, seemingly based on Hebrew-to-Latin correspondences, as observed by John Opsopaus in his reading of manuscripts from the 10th and 11th centuries.[1] Unlike in Greek isopsephy or Hebrew gematria, where the conversions are based on classical utilisation of every glyph as both a letter and a numeral, Latin only utilised a limited set of letters in combinations as ordinary numbers (I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000), and consequently the conversions are not based on routine equivalencies but rather assumed correspondences with other languages.
