Many notable polymaths lived during the Renaissance period, a cultural movement that spanned roughly the 14th through the 17th century, beginning in Italy in the late Middle Ages and later spreading to the rest of Europe. They had a rounded approach to education that was typical of the ideals of the humanists of the time. A gentleman or courtier of that era was expected to speak several languages, play a musical instrument, write poetry, and so on, thus fulfilling the Renaissance ideal. The idea of a universal education was pivotal to achieving polymath ability, hence the word university was used to describe a seat of learning. At this time universities did not specialize in specific areas, but rather trained their students in a broad array of science, philosophy and theology. This universal education, as such, gave them a grounding from which they could continue into apprenticeship to a Master of a specific field. It is important to note that a university education was highly regarded. A person was not considered to need this broad knowledge to apprentice as a carpenter, but to apprentice in the sciences or philosophy it contributed hugely to their being able to comprehend the universe as it was understood at the time. During the Renaissance, Baldassare Castiglione, in his The Book of the Courtier, wrote a guide on becoming a polymath.[citation needed]
