New techniques and questions

The Problem with Early Excavations

Before 1944, archaeologists often dug Harappan sites in a mechanical, unscientific way — they removed earth in uniform horizontal layers, ignoring the natural layers (strata) of the mound. This destroyed crucial evidence about the sequence of human occupation.

Wheeler's Revolutionary Approach

R.E.M. Wheeler became Director-General of the ASI in 1944 and brought two major changes:

1. Stratigraphic excavation — digging must follow the natural layers of the mound, not arbitrary horizontal lines. This preserves the chronological order of deposits.
2. Military precision — Wheeler, an ex-army brigadier, introduced disciplined, systematic methods to archaeology.

Key principle: The sequence of layers (stratigraphy) tells the story of how a site developed over time. Digging across layers mixes up evidence from different periods.

Post-1947 Shifts in Focus

With Partition, major Harappan sites (Harappa, Mohenjodaro) became part of Pakistan. This forced Indian archaeologists to:

• Locate new sites within India through extensive surveys
• Discoveries include Kalibangan, Lothal, Rakhi Garhi, and Dholavira
• Explore Punjab, Haryana, and Kutch — revealing many Harappan settlements

New Questions and Techniques (Since 1980s)

Modern archaeologists now ask:

• Cultural sequence — what is the order of different cultures at a site?
• Site location logic — why were settlements placed where they were?
• Artefact function — what were objects actually used for?

Modern scientific techniques include:

• Surface exploration — recovering traces of clay, stone, metal, plant and animal remains
• Minute analysis — examining every scrap of evidence
• International collaboration — specialists from India, Pakistan, and abroad working together

Wheeler's Personal Account

Wheeler described his first visit to Harappa in 1944:

• Arrived by tonga at night, saw moonlit mounds
• Local officer warned: start at 5:30 AM, finish by 7:30 AM (too hot after)
• Next morning, Wheeler was so amazed by the tallest mound that he and his team worked six hours under blazing sun
• The "mad sahib" (Wheeler himself) set a relentless pace
