Piscine symbols, representing the letter dag (which means “fish”) appear near the necks of two 16th-century B.C.E. storage jars discovered at Gezer, in central Israel. These and eleven other symbols, seven of which have been unambiguously identified, from the Gezer jars constitute the earliest examples yet known of proto-Canaanite script, the world’s first alphabet. The letter dag later came to be known as dalet, the fourth letter of Canaanite and related alphabets (including Hebrew).
