(covers information from several alternate timelines)
Anslem was the first novel written by Jake Sisko. Begun (but not finished) while under the influence of Onaya, an apparently non-corporeal being who fed on creative energy given out by talented individuals. It was suggested by his father, Benjamin Sisko, however, that she only forced out what was already within him. (DS9: "The Muse", "The Visitor")
In its original conception at least, it was somewhat autobiographical. The mother of the main character was deceased, though that was only one of several themes Jake hoped to incorporate. The father of the main character also featured in the first draft.

Background information Edit
It is not known whether Jake Sisko ever finished this book in the main timeline. We only ever see it finished in the alternate timeline shown in "The Visitor". In "The Muse" Benjamin Sisko suggests that his son let the manuscript rest for a while, but eventually start working at it again.
In the Deep Space Nine book trilogy Millennium, Anslem is stated to be a part-autobiographical book that Jake works on every now and then. Short excerpts begin each of the three books in the trilogy. Millennium also indicates that "Anslem" is the Bajoran word for "father."
