Note: Pasargadae was located northeast of Persepolis and was chosen as the capital of the Achaemenid Persians by Cyrus II because it lay near site of his victory over Astyages (550 BCE). The name may have derived from a Persian tribe called the Pasargadae. Buildings in the city were placed at a distance from each other, and palaces were placed in a walled compound irrigated by water channels. The large gate of the compound was guarded by statues of winged bulls. South of the compound was the tomb of Cyrus, a limestone box of eastern Greek design decorated with an Assyrian rosette. During the Islamic periods (beginning with the defeat of the Sasanian army at the battles of Qadisiyeh in 637 CE) the tomb was believed to be the resting place of King Solomon's mother.
