In the fifteenth century prices rose, as the Florentines insisted on having Russian or Circassian girls as being better-looking. Their reputation for honesty and morality did not stand high, and they were often brutally ill-treated and imprisoned in the dreaded prison of the Stinche for stealing, &c. Alessandra Strozzi, writing to her son Filippo at Naples in 1465, warns him about two he thought of buying.

“Thou tellest me in thy letter of the 28th that a slave is offered thee who was here with Lionardo Vernacci and that thou wouldest have taken her but for the old one thou hast in the house. I must tell thee that she is not fit for thee according to my ideas. Lionardo’s wife had her four or five years, and as she did not learn and was of a bad disposition they feared she might do some ill to herself or to others, so they got rid of her; she was also dishonest. They sold her to Antonio della Luna, with whom she remained but a short time, as he would not have her and sent her back; so she was sent down there [Naples]. Lionardo’s wife had her for sewing, but she had no aptitude for it. Had she been a good servant they would have kept her for themselves. Thou sayest thou hast one now who belonged to Filippo degl’ Albizzi; she was highly thought of and well treated, but was sold because wine began to affect her and made her extremely lively, and also she was immoral. Having a wife and children in the house he would not keep her. She is praised for loyalty and intelligence. Now do as thou wilt.... I have told thee what I know.”[29]

Towards the end of the fifteenth century the manumission of slaves begins to be mentioned in wills together with bequests to hospitals and convents. By the word este civis romana the slave became a free man or woman, could own property, buy and sell, and act in all other respects as if free-born.[30]

Cosimo de’ Medici to his son Piero de’ Medici at Venice

Send by the women who are returning the things mentioned in the list given to Ser G., and look closely yourself, as is but right, after what is sent here and what remains there.

Put the books that are in my desk into a small strong-box so that they should not be opened, and see that the others which we lent should be sent back in such a manner as not to spoiled.

It seems to me that thou shouldest remain at Venice this winter, for there is nothing doing here, and thus thou canst devote thyself to learning something of the affairs of the bank and of book-keeping. I have ordered a book which thou art to keep according to instructions which Antonio Martelli will send thee. In this way thou wilt learn book-keeping properly, and canst return here at Lent.

Be careful to conduct thyself well at home and abroad, so as not to put either me or thyself to shame. Consort with our friends according to usage; make thyself acquainted with what is doing in the company, and learn what is going on.

Try to get back that book on ethics from the son of Messer P. Corro,[31] and the Sallust and Suetonius I lent to G. Lignacci, in one volume. If they have done with them get them back before S. Lucia (13th December). Also get back a small volume of Chrysostom which they say they want to translate. Keep the books from Nicola de Servi, as is said in the minute given to Ser G., and send back twenty or twenty-five volumes of our books of each subject. Thou canst put them with the quilts, or in other bales, so that they should not be spoiled, and take care that those which remain are not gnawed or spoiled.

As I said before, for many reasons I think it would be better for thee to remain at Venice, for nothing of any good is doing here. But if thou wishest to return here, do as thou wilt. Nought else to say.—[No date.]
