Archaeological evidence at Byblos, particularly the five Byblian royal inscriptions dating back to around 1200–1000 BC, shows existence of a Phoenician alphabet of twenty-two characters; an important example is the Ahiram sarcophagus. The use of the alphabet was spread by Phoenician merchants through their maritime trade into parts of North Africa and Europe. One of the most important monuments of this period is the Temple of the Obelisks, dedicated to the Canaanite war god Resheph, but this had fallen into ruins by the time of Alexander the Great.
