Trabea is a short cloak that served among the Etruscans as a sign of royal power.
Trabea was a very ancient type of toga and served as the clothing of saliy and augurs  .
According to Servius , three types of trabey were used  :
- purple - the clothes of the gods;
- purple with white gaps - the robe of the kings;
- with bright red horizontal stripes and a purple border - the augurs robe.
Later, the trabey with bright red horizontal stripes on solemn occasions was worn by the Roman kings, horsemen and augurs, and then consuls . The imperial trabya became completely purple  .
