Date of the Book of the Song of Solomon

Date - 1014 BC Approximately. There is no way to know the exact historical circumstances behind this event. We know it was Solomon because it mentions him by name, but it is uncertain whether he married a Shulamite woman of Israel, or Pharaoh's daughter. Others have included a third person, a shepherd who the girl of Shulam is in love with despite the kings desire for her. This book was included in the Septuagint (Greek translation of the Hebrew Canon) and was known in the time of Jesus as part of the Hebrew Scriptures though some critics doubt it should be in the Bible.
