The phrase identifies a specific segment of a larger literary work. The constituent parts indicate a narrative (“when the black wolf calls me”) broken down into sequential divisions (“chapter 1”). This designation is common in serialized fiction, denoting the initial entry in a series or novel.
This type of identifier serves multiple purposes. It provides a clear reference point for readers and critics, facilitating focused discussion and analysis. Furthermore, it is essential for organization and indexing within digital libraries and online platforms. Historically, chapter divisions have aided in pacing and thematic structuring of long-form narratives, allowing authors to manage plot and character development effectively.
