- Snail (Wikipedia)
A snail is a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name snail is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word “snail” is used in this most general sense, it includes not just land snails but also numerous species of sea snails and freshwater snails. Gastropods that naturally lack a shell, or have only an internal shell, are mostly called slugs, and land snails that have only a very small shell (that they cannot retract into) are often called semi-slugs.
- Ferdinando de’ Medici, Grand Prince of Tuscany (Wikipedia)
Ferdinando de’ Medici (9 August 1663 – 31 October 1713) was the eldest son of Cosimo III de’ Medici, Grand Duke of Tuscany, and Marguerite Louise d’Orléans. Ferdinando was heir to the Grand Duchy of Tuscany, with the title Grand Prince, from his father’s accession in 1670 until his death in 1713. He is remembered today primarily as a patron of music. An excellent musician himself (sometimes called “the Orpheus of princes”), he attracted top musicians to Florence and thus made it an important musical center. Through his patronage of Bartolomeo Cristofori, Ferdinando made possible the invention of the piano.
