4Q240 (or 4QCanta) is believed to be a commentary (or pesher) on the Song of Songs, also known as 'Canticles'. Written in Hebrew, it was found in Cave 4 at Qumran in the Judean Desert and comprises part of the Dead Sea Scrolls. From its palaeography (script) it has been identified as being early-Herodian.
Included in Milik's original list, but this fragment has never been located.[1]
