The image depicting the cover of this book presents the sculpture entitled ‘Apolo Belvedere’. exhibited at the Pio-Clementino Museum in the Vatican. The date of their origin and authorship is controversial, but it is considered to be a Roman copy, in marble, of a lost Greek original. Representing Greek deus Apolo, this sculpture has become the expression of perfection, characteristic of Greek civilisation. It should be noted that that ideal, although referring to beauty, was not restricted to aesthetic appearance, since the beauty was associated, by the Greeks, with love, wisdom, justice, cause, beauty and courage. This association implies the idea of a superior man, perfect, as a cultural model, guided by greater values, who would generate the best citizens. This conception has its roots in the homerical period and is consolidated at the height of Athensan democracy. Apolo, son of Zeus and Leto, is the deus of music, arts, teachers, purification, curing, sunlight, fair measure, youth. It summarises the principles of order, harmony, reason, balance and moderation. Because it is a multifaceted, sometimes paradoxical, vintage, as it also presents aspects that are contradictory to its own qualities, it harmonises the poarities in itself, directing them towards the ideal of culture and wisdom. As a result, the Greek people became the expression of the ideal of perfection and was considered to be a genuine personalisation of the Greek spirit.
