The menorah is the major symbol of Hanukah since the small amount of oil the Macabees had to keep the eternal flame burning lasted for 8 days. This miracle is celebrated by lighting one candle more on each of the eight days of Hanukah.
The menorah has nine candle holders. The one in the middle is the shamos with which you light the others. On the first day, you light the shamos and use it to light one other candle. On the second day, you light the shamos and use it to light two others candles. You keep this up until the eighth day when the shamos and all eight other candles are burning.
