According Mun, his father ‘was in his time famous amongst Merchants, and well known to most men of business, for his general Experience in affairs and notable into Trade’ (1664: i). Early in life, Mun gained experience as a merchant in Italy, trading especially with Turkey and the Levant. He served under Duke Ferdinand of Tuscany, from whom he borrowed forty thousand crowns, free of interest. He lived in Leghorn for some time, before returning to England.
