mesomath 2.1.2

A robust sexagesimal, metrological, and astronomical engine for Babylonian mathematics. From the Eduba to the Jupyter Notebook.

🏺 MesoMath v2.1.0

The Mesopotamian Computational Engine for Python.

MesoMath is a high-precision computational framework engineered for the rigorous study of ancient Mesopotamian mathematics, metrology, chronology, timekeeping, and archaeoastronomy. It provides native command-line environments (CLI), Jupyter integration, and authentic epigraphic support (Old Babylonian transliteration and Unicode cuneiform rendering).

✨ What's New in v2.1.0?

MesoMath has evolved into a unified metapackage, structurally decoupling core arithmetic from chronological anchoring systems:

• mesomath Core: Introduces the BabF class for native sexagesimal (base-60) fractional arithmetic without floating-point rounding artifacts.
• mesotimes Subsystem: A dedicated historical engine driving:
  • Empirical & Proleptic Chronology: Seamless alignment with historical cuneiform registers.
  • Elastic Timekeeping: Shifting horizon-based day boundaries (Sunset-to-Sunset) and dynamic nocturnal watches (maṣṣarātu).
  • Archaeoastronomy: High-fidelity celestial positioning and eclipse matrices.

🚀 Quick Start

Installation

Install the complete environment globally using pipx (recommended for CLI apps):

$ pipx install mesomath

The Scribal Console

Launch the pre-configured advanced interactive environment:

$ ibabcalc

1. Dimensional Arithmetic & Fractions

MesoMath manages geometric dimensions and base-60 rational numbers natively:

from mesomath import Blen, Bsur

# Objects understand localized metrological ratios
width = Blen('3 ninda')
area = Bsur('1 sar')

# Dimensional descent via division engine
length = area / width
print(length.prtf())  # Output: '1/3 ninda'

2. Epigraphic Authenticity

Export mathematical computations directly into cuneiform strings or scholarly transliterations:

from mesomath import Bcap

vol = Bcap('3 bariga 2 ban')
print(vol.translit)   # Output: '3(barig) 2(ban2) še'
print(vol.cuneiform)  # Output: 𒑗 𒑐 𒊺

3. Chronology & Archaeoastronomy

Translate continuous timeline anchors into historical calendars and calculate complex planetary visibilities:

from mesomath import ChronDate

# Instantiate a target Julian date
date = ChronDate.from_julian(-378, 5, 17)
print(date.babylonian)
# Output: 'Year 26 of Artaxerxes II, month: 2 (Aiaru), day: 14'

# Generate localized micro-historical data grids
date.day_ephemeris(city='Susa')
