Where it comes from

The story of Basilio

The scorpion story goes back at least to Pliny and circulated in European herbals for well over a thousand years; Nicholas Culpeper was still repeating and disputing it in 1653. Sweet basil was nonetheless grown and eaten throughout the period, which suggests the belief was held loosely. The word basileus meanwhile produced basilica, originally a royal hall and then a church of a particular plan, and basilisk, the little king among serpents. Basil is a major Orthodox name — Basil II ruled Byzantium for fifty years — and Basilio is standard in Italy and Spain. The American figures peak in 1904 with Italian and Hispanic immigration.

Meaning

Greek "royal, kingly"

From basileios, royal, from basileus, a king. Basil the Great, the fourth-century bishop of Caesarea, gave the name to the Church, and it became one of the most common names in the Greek and Slavic Orthodox world. The herb takes the same word, called the royal plant in Greek, and the basilica and the basilisk share the root. Basilio is the Italian and Spanish form.
