Little is known about the satirist Juvenal, other than what can be gleaned from his works. There are ancient scholia, but these are plainly the product of Late Antiquity.
Reading the old 1913 Loeb edition of Juvenal, my eye was drawn to mention of an ancient biography of Juvenal, of dubious veracity. The editor gave the Latin text of it, in the preface, but strangely not an English translation:
Vita D. Junii Juvenalis.—Iunius Iuvenalis, libertini locupletis incertum est filius an alumnus, ad mediam fere aetatem declamavit animi magis causa quam quod se scholae aut foro praepararet. Deinde paucorum versuum satyra non absurde composita in Paridem pantomimum poetamque [eius] semenstribus militiolis  tumentem [hoc ?] genus scripturae industriose excoluit. Et tamen diu ne modico quidem auditorio quicquam committere est ausus. Mox magna frequentia magnoque successu bis ac ter auditus est, id ea quoque quae prima fecerat inferciret novis scriptis:
Quod non dant proceres, dabit histrio. Tu Camerinos
Et Bareas, tu nobilium magna atria curas?
Praefectos Pelopea facit, Philomela tribunos. (vii. 90-92)
Erat tum in deliciis aulae histrio multique fautorum eius cottidie provehebantur. Venit ergo Iuvenalis in suspicionem, quasi tempora figurate notasset, ac statim per honorem militiae quamquam octogenarius urbe summotus est missusque ad praefecturam cohortis in extrema parte tendentis Aegypti. Id supplicii genus placuit, ut levi atque joculari delicto par esset. Verum intra brevissimum tempus angore et taedio periit.
I found this 1857 translation online, by Maclaine:
Junius Juvenalis, the son or the alumnus (it is uncertain which) of a rich freedman, practised declamation till near middle life, more for amusement than by way of preparing himself for school or forum. Afterwards, having written a clever satire of a few verses on Paris the pantomimus, and a poet of his, who was puffed up with his paltry six months’ military rank, he took pains to perfect himself in this kind of writing. And yet for a very long time he did not venture to trust any thing even to a small audience. But after a while he was heard by great crowds, and with great success, several times: so that he was led to insert in his new writings those verses which he had written first:
What our great men won’t give you, the actor will. Why
frequent the high antechambers of the Camerini and Bareae?
It is the Pelopea that appoints our Prefects, and the Philomela our Tribunes. (vii. 90-92)
The player was at that time one of the favourites at court, and many of his supporters were daily promoted. Juvenal, therefore, fell under suspicion as one who had covertly censured the times; and forthwith under colour of military promotion, though he was eighty years of age, he was removed from the city, and sent to be praefectus of a cohort on its way to the farthest part of Egypt. That sort of punishment was determined upon as being suited to a light and jocular offence. Within a very short time he died of vexation and disgust.”
The remarks about this text in the Loeb are frustratingly vague. Maclaine also is vague, but he tells us a little more. There are, it seems, a number of these biographies, attached to various manuscripts, and he dismisses the lot. He continues:
Another of these notices states that Juvenal was born at Aquinum, in the reign of Claudius; that he returned from exile, survived the reign of Trajan, and finally died of old age in a fit of coughing.
In a third we are told that when he returned to Rome, finding his friend Martial was dead, he died of grief in his eighty-first year.
A fourth says it was Domitian who exiled him; that he never returned, but that after correcting and adding to hi. Satires in Egypt, he died there of old age in the reign of Antoninus Pius.
From a fifth we learn that he was advanced to the equestrian rank through his own merit; that the place of his honourable exile was Scotland, and that the motive was that he might be killed in battle; that the emperor in a despatch addressed to him with the army, wrote these words, “et te Philomela promovit ” (alluding to his own epigram), and that, learning from this the anger of the emperor, he died of a broken heart.
The sixth memoir makes Trajan the emperor, Paris being still the hero of the epigram, and agrees with the fifth about Scotland.
A seventh agrees substantially with the first, except that the emperor is said to have been Nero.
These seven are published at the end of Jahn’s edition.
Jahn’s 1851 edition does indeed contain this material, together with the ancient scholia. It tells us that this first biography was edited by Lorenzo Valla, no less, as by “Probus”, and that it appears at the end of codex “P”, the Pithoeanus, now Ms. Montpellier 125 (9th c.), in a “more recent hand”; plus three other manuscripts from the 10th-13th centuries.
The other six biographies seem to be taken from a range of individual manuscripts, described vaguely, which we may guess to be late, and mostly at second-hand.
It’s good to have this material, but Jahn is now an exceedingly long time ago. A. E. Housman’s 1905 edition is online here, with its mighty and often amusing preface, which I first read reprinted among that great poet and author’s literary works. But he does not print the scholia or the vitae.
Fortunately I was able to locate a bibliography online in preview, from which I learn that the standard edition today is that of W. V. Clausen, A. Persi Flacci et D. Iuni Iuuenalis satura, Oxford, 1992. This “includes the ancient biography”. The new Loeb is even more recent. Sadly I have no access to either.
Is it really the case that Jahn is the most recent edition of much of this biographical material? Truly?
- The allusion is to honorary appointments to the military tribunate (imaginariae militiae genus, Suet. Claud. 25), a system instituted by Claudius in order that the holder might obtain equestrian rank. The word militiola means “a trumpery period of military service.”↩
