 The Israeli scholar and archaeologist Adam Zertal identifies Sisera with the sea people called Shardana (or Sherden), arguing that Sisera came from the island of Sardinia.Zertal and Oren Cohen proposed that the excavation at El-Ahwat, between Katzir-Harish and Nahal Iron, is the site of Harosheth Haggoyim, Sisera's military base.The Jewish Encyclopedia reports that possibly his father was Shamgar.
