Christina Rossetti's (1830–94) best renowned poem is arguably "Goblin Market." It's a long narrative poem about two sisters, Lizzie and Laura, and how Laura succumbs to temptation and consumes the fruit sold by the poem's title's goblins. The poem was written when Christina was only twenty-one years old and has been called her "most famous work." Goblins are mischievous creatures in English folklore. They often take on human form to commit crimes or act as spies for their masters. Goblins can be good or bad; some behave like demons while others are simply silly. There are several types of goblins including brownies, gnomes, and leprechauns. Goblin markets were popular during the medieval times when people would go to holy sites to sell sacrificial gifts such as chickens, gold, and wine. As these places began to lose their religious significance, they just became regular markets where people could buy and sell anything. Goblins usually steal what you leave behind. If you leave your cloak behind in a place where there are goblins, then they will steal it. So if you don't want your belongings stolen, then you should keep them with you at all times! Goblins can be good or evil depending on who you ask. Some consider them to be children's toys while others see them as real living creatures that should be treated with respect.
