"In a cylinder from the British Museum, a cylinder dating back to around 800 BCE., Tiāmat has the exact shape of a serpent, as long as the seal itself. [...] In addition to some other similar cylinders, with Tiāmat in the form of a serpent, we also have cylinders with Tiāmat in the guise of a lion-griffin or dragon. This depiction of the monster is very common in the last period, but it is nothing more than an artistic variant of the first."
