Historians reconstruct ancient India’s past using archaeology, inscriptions and coins. Each source type has its own methods and limitations.

Must Know
Three Ways to Read the Past
Archaeology
- ScopeArchaeology studies physical remains: pottery, tools, seals and structures.
- CunninghamAlexander Cunningham is called the ‘Father of Indian Archaeology’. He founded the Archaeological Survey of India (ASI) in 1861.
- MethodExcavations rely on stratigraphy, the study of layered soil deposits where deeper layers are usually older.
Epigraphy
- ScopeEpigraphy is the study of inscriptions.
- PrinsepJames Prinsep deciphered the Brahmi script in 1837, then used it to crack Kharosthi the next year.
- KharosthiKharosthi was written right to left, unlike most other ancient Indian scripts.
Numismatics
- ScopeNumismatics is the study of coins.
- ValueCoins reveal a ruler’s name, title and approximate date, plus the kingdom’s extent based on where they are found.
Good to Know
Reading Inscriptions
Ashoka’s Edicts
- CountAshoka’s edicts survive in about 33 inscriptions, in four groups: Major and Minor Rock Edicts, and Major and Minor Pillar Edicts.
- LanguageMost use the Prakrit language in Brahmi script; the northwest used Kharosthi, and a few frontier edicts even used Greek and Aramaic.
The Prayag Prashasti
- ContentThe Prayag Prashasti, or Allahabad Pillar Inscription, is a Sanskrit eulogy for Emperor Samudragupta.
- AuthorHis court poet Harisena composed it in the 4th century CE, carved onto an older pillar that already carried Ashoka’s edicts.
Copper-Plate Grants
- GrantsCopper-plate grants, called tamra-patra, record land grants made by kings.
- ValueThey often include exact dates and family lineages, making them valuable for historians.

Dating and Cross-Checking
Carbon-14 Dating
- MethodArchaeologists use Carbon-14 dating to estimate the age of organic remains like charcoal, wood or bone.
- RangeIt works reliably for material up to roughly 50,000 years old.
Coins and the Indo-Greeks
- DiscoveryCoin evidence revealed over 30 Indo-Greek kings, far more than texts alone.
- TextsGreek and Roman texts name only a handful of these rulers.
A Fuller Picture
- MethodCombining archaeology, epigraphy and numismatics gives historians a fuller, cross-verified picture than any single source type alone.
