Auctions were recorded as early as 500 BC. Auctioneers and gavels came later, but at the beginning of the long history of auctions, the proceedings were a little more dramatic. The auctioneer was referred to as the 'Magister Auctionarium', and instead of using a gavel to commence the auction he would use a spear.
The entire Roman Empire was once put up for Auction. The most advanced civilisation in the world was once put up for sale to the highest bidder during the year of 193 AD. Friendly Trans-Tasman rivalry showed it's colours in 2006 when a cheeky Australian listed the entire country of New Zealand for sale.
Most people are well aware of how auctions work. During an auction, an item is placed up for sale and people can bid on it until it reaches a point where no more bids are coming in. The highest bidder is then awarded the item and allowed to take it home after paying for it.
Most auctioneers supply bidders with a catalog ahead of time.
