The Star of Ishtar
Eight points for the planet Venus, and the standard way of writing a goddess into a scene without drawing her.
What the sources claim for it
Ishtar present as guarantor. On a boundary stone, a divine witness to the terms carved beneath it.
History
Where does the Star of Ishtar come from?
Mesopotamian art identifies deities by emblem, and Ishtar's is an eight-pointed star or rosette standing for Venus, the planet she governs. It appears on cylinder seals, on boundary stones and on the Ishtar Gate's programme, usually in a row with the crescent of Sin and the disc of Shamash — moon, sun and Venus as the three visible authorities of the sky.
The convention is worth stating plainly because it is unlike anything later in this corpus. These are not secret marks. They are captions: a scribe or a stonecutter uses them the way a modern document uses a letterhead, and a literate viewer reads which gods are guaranteeing the object.

Who is it attached to?
Figures who carry it
An attribute rather than a signature — held, worn or associated in the texts and the images.
Afterwards
What did it turn into?
The eight-pointed star passed into Islamic geometric ornament and into modern national and commercial heraldry across the region, entirely detached from the goddess.
Which texts describe it?
Oldest first, with what each one does with the mark. A mark described in a Bronze Age incantation and a mark first drawn in a seventeenth-century manuscript are different kinds of claim, whatever the shape has in common.
