It is widely known that jerba was the land where Ulysses paused in the course of the Odyssey and had a lot of trouble persuading his crew to get back on board . The myth says that when the boat of Ulysses reached the shore of Jerba , the Jerban people gave them a flowery food to eat , the lotus , and this made them forget everything even their way home . Most of the visitors of Jerba or the island of dreams now , hope that they can find that flowery plant that make them forget their way home .
