This is not like most Michener books, which are generally fictional; this is his personal travelogue of his impressions of many travels all over Spain. It should be understood that it was published in the late 1960s and that much has since changed in Spain since that time. While 'Iberia' is normally taken (in the USA, at least) to incorporate Portugal, Michener is writing almost exclusively about Spain in this book.
Michener clearly loved Spain and knew many Spaniards as friends. He discusses Spain's history, culture, art, literature, dance, geography, sports, and spirituality. Rather than putting all that into nice neat little buckets, he weaves it all together to paint an entrancing picture of the Spanish soul as he knows it.
Unlike many such authors, Michener uses photos very carefully to illustrate aspects of Spanish culture, from the assuredly adamant eyes of the Guardia Civil to the warm smiles of the poorest people. He also takes a lot of time to explain words that are difficult to translate and what they tell us about Spanish culture.
Recommended with equal enthusiasm whether from the viewpoint of history, religion, culture, or art. Also of special value to those living in Spanish-speaking countries or regions with large Hispanic populations, as Spain's influence on those cultures, as a mother country, is readily apparent.
Bravo, Sr. Michener. Faltan mucho a Ud.
