Astroit is a term primarily used in the field of heraldry, referring to a charge or motif that is placed diagonally across an escutcheon or shield. Derived from the French word "astroit," meaning "slanted," this term is typically used to describe a significant symbol, such as a stripe, band, or other decoration, that extends diagonally from one corner of the shield to the opposite corner.
In heraldry, a branch of historical study focused on coats of arms, the astroit is positioned from dexter chief (upper right corner) to sinister base (lower left corner) or vice versa, giving the appearance of a diagonal line across the shield. This distinctive placement is often used to denote an honorable or noble lineage, as well as to establish familial or communal affiliations.
Astroits can vary in size, width, and color, and can be charged upon or superimposed over other heraldic charges or insignia, such as animals, plants, or mythical creatures. They add depth, interest, and individuality to a coat of arms, highlighting the ancestral or personal significance of the design.
In summary, an astroit is a diagonal heraldic charge that extends from one corner of the shield to the opposite corner. It serves as a decorative element and conveys meaning, often in the context of heraldic traditions and affiliations.
