The zig-zag road up to the temple was lined with statues—thousands of them, some in gold and silver. They were votive offerings from pilgrims—kings and states as well as individuals.
The temple hill looked a little like some famous cemeteries, with rows of marble figures and family memorials with inscriptions on them.
The Temple was fabulously rich from donations. The Emperor Nero looted it when Rome overran Greece. He carried off, besides gold, five hundred statues. Yet just a few years later, when Pliny the Younger visited Delphi, there were still three thousand standing.
Of course everyone went to Delphi to consult the oracle.
