Mythologie und Geschichte

Für dieses Sternbild existieren manche Deutungen. Die Griechen nannten es Deltoton, die Römer Triangulum und die Araber El Muthalleth, was ebenfalls Dreieck bedeutet. Einige sagen, Triangulum repräsentiere auch die Insel Sizilien, welche von Zeus dadurch geehrt wurde, dass ihr Abbild unter den Sternen zu sehen ist. Einer der früheren Namen von Triangulum war Sicilia. Aratos von Soli beschreibt diesen Ort folgendermaßen: "In der Nähe der Andromeda ist die Insel Sizilien, die einem Dreieck ähnelt, dessen kürzerer Teil durch nahe aneinanderliegende Sternchen geschmückt ist." Bei den Ägyptern war dieses Sternbild ein Sinnbild des Nildeltas und eine Ehrung für die alexandrische Wissenschaften. ^{[7, 21]}
