The term comes from the Latin cento, a cloak made of patches; and that from the Greek κέντρων (gen. κέντρωνος). The Roman soldiers used these centones, or old stuffs patched over each other, to guard themselves from the strokes of their enemies. Others say, that centos were probably used for the patches of leather, etc., with which their galleries or screens, called vineae, were covered; under which the besiegers made their approaches towards any place. Hence centonarii, the people whose business was to prepare these centos.
The cento originated in the 3rd or 4th century. The first known cento is the Medea by Hosidius Geta, composed out of Virgilian works, according to Tertullian. However, an earlier cento might be present in Irenaeus's late 2nd century work Adversus Haereses. He either cites or composes a cento as a demonstration of how heretical Christians modify canonical Gospels.
Ausonius (310–395) laid down the rules to be observed in composing centos. The pieces, he says, may be taken either from the same poet, or from several. The verses may be either taken in their entirety, or divided into two; one half to be connected with another half taken elsewhere. Two verses should never be used running, nor much less than half a verse be taken. In accordance with these rules, he made a cento from Virgil, the Cento Nuptialis.
Faltonia Betitia Proba wrote a Cento vergilianus de laudibus Christi, in which she details the life of Jesus and deeds of the Old and New Testaments; it was written entirely in centos taken from Virgil.
In the Greek World, centos are mainly composed by verses taken from Homer.
The Politics of Justus Lipsius (Politicorum Libri Sex, 1589) consist only of centos; there being nothing of his own but conjunctions and particles. Etienne de Pleure did the same as Proba in Sacra Aeneis (1618). Alexander Ross did the same thing in his Virgilii Evangelisantis Christiados (1634), his most celebrated work of poetry.

- AH 1.9.4: 4. Then, again, collecting a set of expressions and names scattered here and there [in Scripture], they twist them, as we have already said, from a natural to a non-natural sense. In so doing, they act like those who bring forward any kind of hypothesis they fancy, and then endeavour to support them out of the poems of Homer, so that the ignorant imagine that Homer actually composed the verses bearing upon that hypothesis, which has, in fact, been but newly constructed; and many others are led so far by the regularly formed sequence of the verses, as to doubt whether Homer may not have composed them. Of this kind is the following passage, where one, describing Hercules as having been sent by Eurystheus to the dog in the infernal regions, does so by means of these Homeric verses—for there can be no objection to our citing these by way of illustration, since the same sort of attempt appears in both:— "Thus saying, there sent forth from his house deeply groaning."— Od., x. 76. "The hero Hercules conversant with mighty deeds."— Od., xxi. 26. "Eurystheus, the son of Sthenelus, descended from Perseus."— Il., xix. 123. "That he might bring from Erebus the dog of gloomy Pluto."— Il., viii. 368. "And he advanced like a mountain-bred lion confident of strength."— Od., vi. 130. "Rapidly through the city, while all his friends followed." — Il., xxiv. 327. "Both maidens, and youths, and much-enduring old men."— Od., xi. 38. "Mourning for him bitterly as one going forward to death." — Il., xxiv. 328. "But Mercury and the blue-eyed Minerva conducted him."— Od., xi. 626. "For she knew the mind of her brother, how it laboured with grief."— Il., ii. 409. Now, what simple-minded man, I ask, would not be led away by such verses as these to think that Homer actually framed them so with reference to the subject indicated? But he who is acquainted with the Homeric writings will recognise the verses indeed, but not the subject to which they are applied http://www.newadvent.org/fathers/0103109.htm
