In typography, an asterism is a rarely used symbol consisting of three asterisks placed in a triangle (⁂). It is used to call attention to a passage or to separate sub-chapters in a book. It is Unicode character U+2042: [⁂].
Often, this symbol is replaced with three, sometimes more, consecutive asterisks or dots. Otherwise, an extra space between paragraphs is used. An asterism or its analogue may be used in conjunction with the extra space to mark a smaller subdivision than a subchapter.
