Definition - A rarely used symbol consisting of three asterisks placed in a triangle. It is used to call attention to something (e.g. a sub-chapter in a book).

1. Often three consecutive asterisks or dots are substituted if the symbol itself isn't available.
2. Don't confuse it with the "therefore sign," which is three dots placed in a triangle.

Etymology -
The word derives from the Latin aster, star. It initially denoted any grouping of stars (e.g. the Big Dipper).

Oxford English Dictionary -
Its first citation in this sense is from 1649: "This full Quotation, by an Asterisme Set in the margent of a middle Page."
(G. Daniel Trinarch. xvi)
