Iconography of Deities and Demons (IDD).

“All three types begin to appear in the late 2nd millennium. Some possible antecedents are noted by GREEN (1993-97: 252; see also nos. 66-70 belonging to the early Atlantid series, which MATTHEWS 1990: 109 dates to the 14th century).
They could, however, have had a different connotation before being adopted into the sages tradition. Although late texts attribute the tradition of sages to early historical times, no iconographic evidence supports such antiquity for the tradition.
Early dated examples of type 2 on sculpture come from the Terqa (Tell Ashara) stela of Tukulti-Ninurta II (890-884 BCE) (67) and the entrance to the Ninurta temple at Nimrud, probably installed by Assurnasirpal II (883- 859 BCE) (55*).
Huge sculptures of the fish-cloak Apkallu were used likewise in the Southwest Palace of Sennacherib (704-681 BCE) (53 – 54 ).
Type 3 first appears on Middle Assyrian seals, and becomes popular in the 9th-7th centuries both in Assyria and Urartu, often in combination with the sacred tree.
Type 2, on the other hand, appears around the same time in Babylonia, and is taken over in Assyria in the 9th-7th centuries.
Type 1 may have begun early in Assyria of the 1st millennium.
Type 2 is found in Achaemenid (66) and Seleucid (MCEWAN 1982: nos. 30, 40) times.
As shown above, Assyria is the region where Types 1 and 2 were first found, with extension of Type 1 to Carchemish, and of Types 1 and 3 to West Semitic stamp seals (if they are genuine) and to Urartu, probably all under Assyrian influence.
The Babylonian Type 2 is more restricted, moving from Babylonia into Assyria, but from there to Pasargadae in West Iran, and thence into Seleucid art (MCEWAN 1982: nos. 30, 40).
Types 1 and 3 occur in Neo-Hittite/Aramaean sculpture at Carchemish (30), Sakce-gözü (80), and Malatya (31–32)
The three types mainly occur on Assyrian palace sculpture (1*–2, 6*–7, 17–18, 20, 22, 26, 53–55*, 67, including representations on buckets held by sages [e.g., PALEY 1976: pls. 16, 20, 28a-b] and on garments PALEY 1976: pl. 24a), on Assyrian wall-painting (16, 19), on seals (8*–9*, 11–14*, 33*–34*, 38, 41*–47, 52*, 63, 68*– 75*) or seal impressions (3–5, 49–51), carved ivory (10*, 21, 76*–79) found in Assyria, as groups of apotropaic clay figurines (56–62*), on amuletic plaques (35), on various Urartian objects (15*, 24–25, 27–29, 36*, 77) of stone and metal (pendants, horse frontlets, etc.), and as clay foundation figurines (65).
None are found on boundary stones of the Kassite and post-Kassite periods, nor on sealings from Emar tablets of the 12th century, nor among mid-7th century sculptures from Assurbanipal’s North Palace at Nineveh.
The discrepancy between the written tradition in which the sages represent early antiquity, and the much later chronology of the iconographic evidence is striking. Babylonian and Assyrian traditions seem to have arisen separately. The diffusion of the probably Assyrian types 1 and 3 is different from that of the essentially Babylonian type 2.
Types 1 and 3 are closely associated with royal ritual in their scenes with the sacred tree and winged disc, and type 2 is especially associated with sickness, presumably as a healer. These associations make it likely that the bucket and cone, a hallmark of all three types, represent purification and blessing.”
