Study Notes
Lebombo Bone
- Discovered in 1970 in the Lebombo Mountains of Swaziland
- Dating: circa 35,000-40,000 years old
- Made from a fossilized animal bone (likely an antelope)
- Features:
- 29 distinctive markings, including 13 pairs of marks and 16 single marks
- Markings are organized into a sequence, suggesting a counting system
- Some marks are grouped together, possibly indicating a base-10 system
- Interpretation:
- Possibly used for counting or tracking purposes
- May be an early example of a primitive calculator
- Shows evidence of mathematical thinking in early humans
Ishango Bone
- Discovered in 1960 in the Democratic Republic of Congo
- Dating: circa 18,000-20,000 years old
- Made from a fossilized bone of a Nile crocodile
- Features:
- Series of markings, including:
- 168 markings on one side, grouped into 16 rows
- 48 markings on the other side, grouped into 8 rows
- Markings include:
- Tally marks ( single strokes)
- Groups of 2-6 marks, possibly indicating multiplication
- Arithmetical patterns, such as 10+1, 20+1, 30+1, etc.
- Series of markings, including:
- Interpretation:
- Possibly used for mathematical calculations, such as counting, addition, and multiplication
- May have been used for astronomical observations or tracking of lunar cycles
- Shows evidence of advanced mathematical thinking in early humans
- Considered one of the oldest known examples of a mathematical tool
