The kausia (Greek καυσία) is a cap associated with Macedonia and the Hellenistic world. Images show rounded soft caps and forms with a more pronounced spreading top. Coins of Antimachus I of Bactria depict it with a royal diadem. Such images attest its use without providing a complete fabric pattern.
Its resemblance to the modern pakol is useful for comparing shape, but does not prove an uninterrupted tradition or the direction of borrowing. The absence of a similar cap from one relief does not settle its origin either.
Two modern reconstructions can use rounded or conical tops. In the first, a circular crown joins a fabric strip forming a rolled edge; in the second, removing a sector from a circle produces a shallow cone. Linings and folds help adjust the fit, but remain reconstruction choices unless supported by a specific find.
Fresco colours must be assessed in light of pigment preservation. A pale kausia on one monument does not show that all examples were white. A ribbon on a royal cap may be a diadem rather than merely an adjustment cord.
Reconstruction should follow a specific image, identify restored details and test wearing comfort. The kausia, conical pilos and broad-brimmed petasos should not be conflated: they are distinct forms of headwear.
