The words of the veteran pleased Muza ben Nosier, and he gave his consent; and Taric departed with four galleys and five hundred men, guided by the traitor Julian.[16] This first expedition of the Arabs against Spain took place, according to certain historians, in the year of our Lord seven hundred and twelve; though others differ on this point, as indeed they do upon almost every point in this early period of Spanish history. The date to which the judicious chroniclers incline is that of seven hundred and ten, in the month of July. It would appear from some authorities, also, that the galleys of Taric cruised along the coasts of Andalusia and Lusitania, under the feigned character of merchant barks: nor is this at all improbable, while they were seeking merely to observe the land, and get a knowledge of the harbours. Wherever they touched, Count Julian despatched emissaries, to assemble his friends and adherents at an appointed place. They gathered together secretly at Gezira Alhadra, that is to say, the Green Island; where they held a conference with Count Julian in presence of Taric ben Zeyad.[17] Here they again avowed their readiness to flock to his standard whenever it should be openly raised, and made known their various preparations for a rebellion. Taric was convinced, by all that he had seen and heard, that Count Julian had not deceived them; either as to his disposition or his means to betray his country. Indulging his Arab inclinations, he made an inroad into the land, collected great spoil and many captives, and bore off his plunder in triumph to Muza, as a specimen of the riches to be gained by the conquest of the Christian land.[18] CHAPTER X.
