After one of the many quarrels and reconciliations between these fierce brethren, there was an exchange of hostages for the observance of the terms of the treaty. These were not taken from among the Franks, who were too proud to submit to captivity, but from among the Gaulish nobles, a much more convenient arrangement to the Frankish kings, who cared for the life of a 'Roman' infinitely less than even for the life of a Frank. Thus many young men of senatorial families were exchanged between the domains of Theodrik to the south, and of Hildebert to the northward, and quartered among Frankish chiefs, with whom at first they had nothing more to endure than the discomfort of living as guests with such rude and coarse barbarians. But ere long fresh quarrels broke out between Theodrik and Hildebert, and the unfortunate hostages were at once turned into slaves. Some of them ran away if they were near the frontier, but Bishop Gregory was in the utmost anxiety about his young nephew Attalus, who had been last heard of as being placed under the charge of a Frank who lived between Treves and Metz. The Bishop sent emissaries to make secret enquiries, and they brought word that the unfortunate youth had indeed been reduced to slavery, and was made to keep his master's herds of horses. Upon this the uncle again sent off his messengers with presents for the ransom of Attalus, but the Frank rejected them, saying, 'One of such high race can only be redeemed for ten pounds' weight of gold.' This was beyond the Bishop's means, and while he was considering how to raise the sum, the slaves were all lamenting for their young lord, to whom they were much attached, till one of them, named Leo, the cook to the household, came to the Bishop, saying to him, 'If thou wilt give me leave to go, I will deliver him from captivity.' The Bishop replied that he gave free permission, and the slave set off for Treves, and there watched anxiously for an opportunity of gaining access to Attalus; but though the poor young man--no longer daintily dressed, bathed, and perfumed, but ragged and squalid--might be seen following his herds of horses, he was too well watched for any communication to be held with him. Then Leo went to a person, probably of Gallic birth, and said, 'Come with me to this barbarian's house, and there sell me for a slave. Thou shalt have the money, I only ask thee to help me thus far.' Both repaired to the Frank's abode, the chief among a confused collection of clay and timber huts intended for shelter during eating and sleeping. The Frank looked at the slave, and asked him what he could do. 'I can dress whatever is eaten at lordly tables,' replied Leo. 'I am afraid of no rival; I only tell thee the truth when I say that if thou wouldst give a feast to the king, I would send it up in the neatest manner.'
