Etymology
The Solomon Sea is named after the Solomon Islands. These islands received their name "Islas Salomón" from the legend of the biblical land of Ophir — fabled as the source of King Solomon's wealth which was hoped to be discovered, in the first 1568 voyage by their discoverer Spanish navigator Álvaro de Mendaña de Neira. They were so named after his voyage when it was mapped.[2]
