In order to keep them from seizing a vessel and departing for more attractive regions, Balboa conceived the plan of invading the dominions of Dobaybe, which lay around the head of the gulf, and contiguous to the cannibal country on its eastern boundary. He was obliged to await the return of Valdivia with reinforcements, if he would invade the great and opulent region beyond the mountains, but meanwhile there came to him information of a character that fanned to a flame the slumbering desire to achieve a great discovery. An Indian was brought to him one morning, who said he was the subject of a great cacique living in a golden realm of the interior about one hundred miles from Darien. Its capital was situated on the bank of the very river that emptied itself, by many mouths, into the Gulf of Urabá. Its riches were prodigious, and it derived its name from a wondrous goddess of most ancient times, who, according to Indian tradition, was the mother of the god who had created the sun, the moon, and the stars. She also controlled the elements, he said, sending great storms, with thunder and lightning, which destroyed the habitations of those who did not worship her fervently, but rewarding those who did with abundant crops and success in battle. According to some, this goddess had been at one time an Indian princess, whose capital was in the mountains of Dobaybe, and in whose memory, after her death, a temple had been erected containing a golden idol, which was still worshipped by the natives. Both temple and idol were made of gold, and to the holy shrine it was the wont of Indians far and near to make annual pilgrimages, for the purpose of making offerings of their wealth. Thus, in the course of centuries, the golden temple had become filled with treasure of inestimable value. Its walls were adorned with plates of gold, and its vaults filled with the precious metal, veins of which radiated from them to the various mines with which the region abounded. The idol and the temple were of themselves sufficient to arouse the predatory instinct of the Spaniards; but not alone was their cupidity appealed to, for Balboa was informed that his old enemy Zemaco had retreated to the province of Dobaybe, and was engaged in arousing its cacique to resistance. Inflamed, then, by a lust for gold and their desire for revenge, the followers of Balboa volunteered so readily for the desperate enterprise that he had difficulty in retaining any able-bodied soldiers for the defence of the settlement. One hundred and seventy were finally selected, and embarking them in two brigantines, under command of himself and Colmenares, Balboa sailed up the gulf to the mouth of the river draining the golden country.
