Fernando Pessoa worked as a translator and writer of commercial letters, an advertiser and copywriter, while also trying his luck as a publisher, pioneering inventor, and entrepreneur. The poet of "The Keeper of Flocks" and "Triumphal Ode" also wrote insightful and entertaining texts where he analyzed various theoretical aspects of economics, explained in a simplified and lively manner what free competition, state control, monopoly, public servant, etc. mean, and formulated practical advice with accuracy. He rightfully could be called the poet of economics and commerce.
