The 165th birthday of novelist Bram Stoker has been marked by Google with a Dracula illustration.
The search engine has replaced the multicoloured Google logo on its homepage with an illustration depicting scenes from Bram Stoker's famous gothic fiction novel Dracula.
Stoker was born in Clontarf, Dublin, and was part of the literary staff of the Daily Telegraph in the last decade of the 19th century.
His most famous work, Dracula, was published in 1897.
At the time of its publication it was considered a straightforward horror novel; however, as years have passed literary critics have argued that it distills many of the concerns of Victorian England into its pages.
In particular, the famous bloodsucking and transformation of humans to vampires has proved fascinating for academics, who have admired its potent depiction of desire.
The vampire myth was not just a popular one in an age of repressed sexuality, however, and vampire fiction remains popular today - most obviously in Stephenie Meyer's extremely successful Twilight series.
Dracula was well-received at the time of its release, although it was met with nowhere near the fever that greeted the release of Twilight, which has spawned four novels, one spin-off novella, and five films.
Stoker died after suffering a number of strokes at the age of 64 in 1912.
The first Google Doodle appeared in 1998 when the search engine's founders Sergey Brin and Larry Page replaced the logo with a picture of a Burning Man, to notify the world that they had gone on holiday to the Burning Man Festival.
