Hefa or Hepha in Eusebius of Caesarea 's 4th @-@ century work , Onomasticon ( Onom . 108 , 31 ) , is said to be another name for Sycaminus . This synonymizing of the names is explained by Moshe Sharon who write that the twin ancient settlements , which he call Haifa @-@ Sycaminon , gradually expanded into one another , becoming a twin city known by the Greek names Sycaminon or Sycaminos Polis . References to this city end with the Byzantine period .
