Seleucus II Callinicus
Neriglissar likely died in April 556 BC. The last known documents dated to Neriglissar's reign are a contract from 12 April 556 BC at Babylon and a contract from 16 April that same year at Uruk. The Uruk King List (IM 65066, also known as King List 5), a record of rulers of Babylon from Shamash-shum-ukin (668–648 BC) to the Seleucid king Seleucus II Callinicus (246–225 BC), accords Neriglissar a reign of three years and eight months, consistent with the possibility that Neriglissar died in April.
