Alonso (Alfonso X, King of Castile and Leon in 1252-1284) gave Seville the badge, which is to be seen carved and painted everywhere. It is called El Nodo, and is thus represented "No 8 do"; the hieroglyphic signifies "No ma dexaDo", "It has not deserted me." "madexa" in old Spanish meant a knot, [nodus in Latin means knot and its ablative case is nodo] (..) thus was reproduced unintentionally the old Phoenician merchant mark, the Nodus Herculis (a knot tied very hard, and in which no ends were to be seen) - the knot which guaranteed the genuineness of the contents of every bale: hence the mark of these founders of commerce became the symbol of peace, trade, and of the god of thieves, and was perpetuated by the Greeks in the twisted ornaments of the herald Caduceus of Mercury.
