Passed from hand to hand
Hints in antiquity. Nobody knows how the notebook survived its writer's death.5 Herodian, in the third century, says Marcus loved old literature, «δηλοὶ δὲ ὅσα καὶ ἐς ἡμᾶς ἦλθεν ἢ λεχθέντα πρὸς αὐτοῦ ἢ γραφέντα», “as everything of his that has come down to us, spoken or written, shows” (our translation); he may have meant the Meditations.7,8 Debated among scholars About 364 the orator Themistius told the emperor Valens he had no need of the parangelmata, the “precepts”, of Marcus; whether he meant this book is doubtful.2,5,8
Ancient tradition / legend A late Latin life in the Historia Augusta says that before Marcus left for the war he was asked to publish his precepts of philosophy, and instead discussed them for three days.8 Wikipedia notes that this life, of the rebel Avidius Cassius, is one of the unreliable ones.1
Byzantium. The first clear mention is by Arethas, a bishop of Caesarea in Cappadocia and a great collector of manuscripts. Before 907 he sent a volume of the book to Demetrius, archbishop of Heraclea, saying he had long had an old copy “so old indeed that it is altogether falling to pieces”, and had had it copied.8 Leopold prints the letter's words for it, Μάρκου τοῦ αὐτοκράτορος τὸ μεγαλωφελέστατον βιβλίον, “the most profitable book of the emperor Marcus” (our translation).19 In notes on Lucian, Arethas calls it τὰ εἰς ἑαυτὸν ἠθικά, “the ethical writings to himself”; the manuscript behind the first printed edition was headed more simply τῶν εἰς ἑαυτόν, “of the things to himself”. Arethas' copy is lost, but it is thought to be the likely ancestor of the manuscripts we have.8,19
The Suda, the great Byzantine encyclopedia of the late tenth century, quotes the book some thirty times, from Books 1, 3, 4, 5, 9 and 11, and calls it “a directing” (ἀγωγή) “of his own life by Marcus the Emperor in twelve books”: the first mention of the twelve books.5,8 Under the word ἀκενόσπουδος, “shunning vain pursuits”, it quotes, in its own words, the opening of Book 1, chapter 6 and names its author «Μάρκοϲ ὁ φιλόϲοφοϲ βαϲιλεύϲ», “Marcus the philosopher emperor” (our translation; the reader's text of the Suda prints sigma in its old moon shape, ϲ).15,20,22 Around 1150 John Tzetzes quoted Books 4 and 5, and later Greek anthologies, from the fourteenth to the sixteenth century, took extracts.5,8
Manuscripts. Modern texts rest almost entirely on two witnesses. One is P, the Palatine manuscript from the library of the Elector Palatine Otto Heinrich at Heidelberg, which held the whole work; it was printed in 1558 and then disappeared, so the first printed edition now stands in its place.5,8,19 The other is A, Vaticanus graecus 1950 in the Vatican Library, written on paper in the fourteenth century; it came to the Vatican from the collection of Stefano Gradi in 1683, and about forty-two lines have dropped out of it by accident here and there.5,8,19 Shorter selections survive in a fourteenth-century manuscript at Darmstadt (D, more than a hundred passages from Books 1–9), in a fifteenth-century Paris manuscript (C), and in twenty-five or more manuscripts of an anthology that may be the work of the Byzantine scholar Maximus Planudes. D and C give some independent help; the anthology, practically none.5,19 P and A share the same gaps and hundreds of the same corruptions, down to spelling, so they come from a single earlier edition. Leopold judged that P was cleaner, while A, full of copying slips, often kept the true reading more faithfully.19
Print. Wilhelm Xylander published the first printed edition at Zurich, with a Latin translation and notes, at the urging of Conrad Gesner; the year is given as 1558 or 1559.8,19,21 By his second edition, at Basel in 1568, he no longer had the manuscript.8,19 An anonymous edition printed at Lyon in 1626 first divided the books into numbered chapters, though Xylander's translation had already split them in much the same way.19 Meric Casaubon made the first English translation in 1634, and Thomas Gataker's Cambridge edition of 1652 added voluminous notes.2,5,19 The Vatican manuscript was first used by Cardinal Barberini for an Italian translation in 1675; in 1770 it was copied for J. P. de Joly, whose Paris edition of 1774 was the first to draw on it.19 Modern editions followed: Stich's at Leipzig (1882 and 1903), Leopold's at Oxford (1908), Farquharson's with commentary (1944) and Dalfen's Teubner text (1979; second edition 1987).2,19
