155. Without recurring to the more ancient writers, I shall quote three respectable testimonies which belong to the fourth and seventh centuries: the Expositio totius Mundi (p. 16, in the third volume of Hudson's Minor Geographers), Ausonius (de Claris Urbibus, p. 242, edit. Toll.), and Isidore of Seville (Praefat. ad Chron. ap Grotium Hist. Goth. p. 707). Many particulars relative to the fertility and trade of Spain may be found in Nonnius, Hispania, Illustrata; and in Huet, Hist. du Commerce des Anciens, c. 40, p. 228-234.
