Year: 2008 Language: english Author: Ken Fleming, Austin Weltman, Mark Randolph & Keith Elson Genre: Technical book Publisher: Taylor & Francis Edition: 3rd ISBN: 978-0-203-93764-8 Format: PDF Quality: eBook Pages count: 407 Description: The first historical reference to piling appears to be by Herodotus, the Greek writer and traveler who is sometimes referred to as the ‘father of history’ and who lived in the fourth century b.c. He records how a Thracian tribe, the Paeonions, lived in dwellings erected on lofty piles driven into a lake bed. The piles were driven under some kind of communal arrangement but after a time a law had been made that when a man wished to marry, he had first to drive three piles. Since the tribe was polygamous, the number of piles installed was considerable. This system provided a unique and practical method of founding an expanding settlement.

Description: The first historical reference to piling appears to be by Herodotus, the Greek writer and traveler who is sometimes referred to as the ‘father of history’ and who lived in the fourth century b.c. He records how a Thracian tribe, the Paeonions, lived in dwellings erected on lofty piles driven into a lake bed. The piles were driven under some kind of communal arrangement but after a time a law had been made that when a man wished to marry, he had first to drive three piles. Since the tribe was polygamous, the number of piles installed was considerable. This system provided a unique and practical method of founding an expanding settlement.
