Consider the following statements about the archaeological findings in Harappan towns : I. There is wide occurrence of spindle-whorls in the houses but absence of spinning wheels. II. Weights and measurement scales, complete with graduations have been discovered. III. There are houses built in large part with baked bricks, around relatively spacious courtyards, with their own wells, bathing platforms, and large rooms. Which of the following inferences can be drawn from the above statements ? 1. Statement I suggests that spinning was a laborious activity done at home. 2. Statement II suggests the extent of the scientific knowledge that the Harappans possessed. 3. Statement III suggests the emergence of a common property system. Select the answer using the code given below :

Answer: (A) 1 and 2 only

The correct answer is 1 and 2 only.

Key Points

  • Inference 1 is correct. Spindle-whorls made of terracotta and faience are found in almost every household. This shows that spinning cotton and wool was a common domestic task. Mechanized spinning wheels had not been invented yet, so the work was manual and took much time and effort.
  • Inference 2 is correct. The Harappan civilization used highly standardized weights and measurement scales. Excavations have revealed cubical chert weights and graduated scales made of shell, ivory, and metal. These objects show an advanced understanding of mathematics, geometry, and precision engineering.
  • Inference 3 is incorrect. Private wells, bathing platforms, and baked brick houses with large rooms and central courtyards stress individual household privacy and private property. A common property system would instead mean shared public facilities for daily living, which goes against this evidence of self-contained domestic units.

Additional Information

  • Textile Industry:
  • Actual pieces of dyed cotton cloth have been found at Mohenjo-daro.
  • The spindle-whorls suggest that weaving was a widespread cottage industry.
  • Metrology and Trade:
  • The weight system followed a binary system for lower denominations (1, 2, 4, 8, 16, 32, up to 12,800) and a decimal system for higher weights.
  • Standardization was maintained across vast distances, from Gujarat to Punjab.
  • Architectural Features:
  • Baked bricks were made in a uniform ratio of 1:2:4 (thickness to width to length).
  • Drainage systems were carefully planned. Individual house drains connected to street sewers made of mortar and gypsum.
Why this was asked

The Harappan civilization had uniform weights, measures, and brick sizes across thousands of kilometers, showing remarkable administrative control and trade networks.

UPSC is testing whether students can distinguish between evidence of private property systems versus communal living arrangements in ancient civilizations.

The question checks if students can make correct logical inferences from archaeological evidence rather than just memorizing facts about Harappan discoveries.

Harappan Textile Industry

Ancient And Medieval History spindle-whorls spinning houses

Harappan Textile Industry: Spindle-Whorls & Domestic Production

Must know

Spindle-whorls found in almost every Harappan house indicate widespread domestic spinning

No spinning wheels existed - all textile work was manual and time-consuming

Good to know

Actual dyed cotton cloth pieces discovered at Mohenjo-daro

Textile production was a cottage industry spread across households

Archaeological Evidence

Spindle-whorls made of terracotta and faience appear in virtually every excavated Harappan house, suggesting that spinning cotton and wool was a routine domestic task performed by household members.

Textile Production Evidence

Artifact Type

Significance

Spindle-whorls

Terracotta, Faience

Hand-spinning thread

Universal domestic activity

Cotton cloth pieces

Dyed cotton

Finished textile

Advanced dyeing techniques

Spinning wheels

Mechanized spinning

Pre-industrial technology level

Production Characteristics

Spinning was manual and laborious without mechanized wheels

Every household participated in textile production as a cottage industry

Cotton cultivation and processing were well-developed skills

Dyeing technology was sophisticated enough to create colored fabrics

Exam traps

Trap: Confusing spindle-whorls with spinning wheels - whorls are hand tools, wheels are machines

Trap: Assuming absence of spinning wheels means no textile industry - manual spinning was highly developed

Harappan Weights & Measurements

Ancient And Medieval History weights measurement scales graduations

Harappan Metrology: Standardized Weights & Scientific Precision

Must know

Cubical chert weights following binary and decimal systems discovered

Graduated scales made of shell, ivory, and metal found across sites

Weight ratio followed 1:2:4 standardization across vast distances

Good to know

Demonstrates advanced mathematics and precision engineering knowledge

Scientific Achievement

The discovery of standardized weights and graduated measurement scales across Harappan sites demonstrates sophisticated understanding of mathematics, geometry, and precision engineering - indicating advanced scientific knowledge for a Bronze Age civilization.

Cubical chert weights following binary progression - evidence of advanced mathematical knowledge

Exam traps

Trap: Confusing weight systems - lower denominations used binary, higher used decimal

Trap: Assuming modern measurement units - Harappans had their own standardized system

Harappan Architecture & Housing

Ancient And Medieval History baked bricks courtyards wells bathing platforms

Harappan Housing: Private Architecture & Urban Planning

Must know

Houses built with baked bricks in 1:2:4 ratio around spacious courtyards

Private wells and bathing platforms in individual houses

Evidence supports private property system, not common property

Good to know

Advanced drainage systems connected house drains to street sewers

Architectural Evidence

Harappan houses featured private wells, bathing platforms, and spacious courtyards within individual family compounds, clearly indicating a private property system rather than communal living arrangements.
