Thirteen Satires of Juvenal (leaving out, as often happens, II, VI, and IX, though the work isn't really intended for younger students) is, or was, a minor monument of Victorian scholarship. Its author, John E. B. Mayor, was Professor of Latin at Cambridge University. The commentary is intended less as an aid to understanding and more as an exploration of the environment through a collection of references to related works. Gilbert Highet's Juvenal the Satirist says, “A text with very learned notes on all satires except 2, 6, and 9; the comments consist chiefly of parallel passages, and do not go deeply into problems of text and interpretation.”

Mayor was a philologist and delighted in the details. He contributed five notes to the first volume of Notes and Queries, the Victorian group blog; and nine articles to the first volume of The Classical Review, which was edited by his brother, Joseph. He wrote an article on Latin lexicography for the Journal of Classical and Sacred Philology, in which he summed up his destiny, “there still remains work enough to keep the memory and the understanding employed to the end of life; there will still be new facts to collect, or forgotten facts to recover, to store up, and to classify.”

A . E. Housman, who succeeded Mayor as Latin Professor, a chair that was then renamed for Kennedy, who had refused while he was alive, in his 1911 Inaugural Address, after attributing to Kennedy's Sabrinae Corolla (a collection of translations of English poems into Latin and Greek) his “genuine liking for Greek and Latin” (Kennedy became Regius of Greek at Cambridge; in Stoppard's first scene, AEH tells this and has digs at him and Jowett, the Regius of Greek at Oxford; we still used an edition of Kennedy's public school primer in Form I Latin in the late '60s; I imagine they still uses it today) said of Mayor:

Most good scholars are much fonder of learning than of teaching, and to Munro the duties of his office proved uncongenial and irksome. He resigned the Chair after a tenure of three years, and in 1872 it passed to the venerable man who left it vacant only last December; a scholar who in learning, if that word is taken to mean range and thoroughness of reading, had no equal in England and no superior in Europe. To dwell on the erudition of John Mayor is not merely superfluous but presumptuous; and I will now speak rather of a characteristic on which speech perhaps is not unnecessary. It is well known and sometimes lamented that for all his amplitude of knowledge he left behind him no complete work and no work having even the air of completeness. This regret I do not share; I am much more disposed to recommend for imitation the examples of one who recognized his own bent and followed it, and whose inclinations were exactly in harmony with his talents. Many a good piece of work has been spoilt by the vain passion for completeness. A scholar designs to edit a certain author, a complete edition of whom would involve the treatment of matters to whose study the editor has not been led by his own tastes and interests, and in which he therefore is not at home. The author discourses of philosophy, and the editor is no philosopher; or the author writes in complex metres, and the editor's metrical education stopped short at Porson's canon of the final cretic. It then sometimes happens that the editor, having neither the humility to acknowledge his deficiency nor the industry or capacity to repair it, scrapes a perfunctory acquaintance with the unfamiliar subject, and treats it incompetently rather than not treat it at all; so that his work, for the sake of ostensible completeness, is disfigured with puerile errors, and he himself is detected, not merely in ignorance, but in imposture.

It is the absence of any such vanity, the abstention from all misdirected effort, which redeems and even converts into merit what might else appear defective in the works of Mayor. The establishment and the interpretation of an author's text were not matters in which he took the liveliest interest nor tasks for which he felt in himself a special aptitude: his likings pointed the same way as his abilities, to the collections of illustrative material. I said while he was alive, and I shall not unsay it because he is dead, that this labour is labour bestowed upon the circumference and not the centre of the subject. But this also is work which must be done, and which no other could have done so thoroughly. ‘If a man read Richardson for the story’, said Johnson, ‘he would hang himself’; and much the same may be said not only of Mayor's Juvenal but of a still more celebrated book, Lobeck's Ajax of Sophocles. When you have finished Lobeck's commentary you have imbibed a vast deal of information, but your knowledge and understanding of the Ajax has not proportionally increased. Lobeck himself in his preface admits that this is so; τὸ μὲν πάρεργον ἔργον ὣς ποιούμεθα [, τὸ δ' ἔργον ὡς πάρεργον ἐκπονούμεθα. 'we treat our by-work as work, and perform our work as by-work. ' Agathon, frag. 11]. He in his commentary is not principally the critic nor the interpreter, but the grammarian; and Mayor in his is principally the antiquarian and the lexicographer: his main concern is not with what the author wrote or meant, but with the words he used and the things he mentioned. These he carried in his mind through the whole width of his incomparable reading, and brought back from the limits of the literature all the parallels and imitations and echoes which it contained. What he has bequeathed us is less an edition than a treasure of subsidies: there he saw his true business, and to that business he stuck: and ‘it is an uncontrolled truth’, says Swift, ‘that no man ever made an ill figure who understood his own talents, nor a good one who mistook them’.

(Housman, too, would edit a Juvenal, with just an English introduction and no notes.)

Around 1880, Mayor joined the Vegetarian Society and in 1884 was elected president. At Cambridge, he was not known as a particularly effective lecturer, tending to deliver unadorned citations, as in his commentaries. But he was a proselytizer. M. R. James recalled in his memoir Eton and King's: Recollections, Mostly Trival, 1875-1925 (pp. 181-2):

There was never any translation, or any explanation of an interesting point. Of course Mayor, imagining that everybody was as conscientious as himself, thought that one would go home and look up all these references and copy out the passages in a neat hand. But! At the end of the lecture there was an oasis. I used to carry Mayor's books back to his rooms in St. John's, and he would reward me with a copy of the last number of the Vegetarian Magazine, or refresh me with the reading of a letter he had written to, or received from, one of the Old Catholic Bishops. Innocency, charity, the purest enthusiasm for learning were seen at their best in Mayor: accompanied by a want of sense of proportion (and humour) which could hardly be exaggerated.

In 1886, he greatly expanded the “Advertisement” at the head of his Juvenal, which had been previously unremarkable — the early editions just noting that he had purposely not read anyone else's English edition and containing the ultimately unfulfilled promise to do all sixteen satires, and the enlarged second edition just providing some more details on the text. In this fourth edition, it became a wide-ranging discourse on various matters, including in particular vegetarianism and temperance, only barely managing to return to the topic of Juvenal at the very end. There was so much new material that it was also published separately as a supplement to the first volume.

All of which explains why Mayor's Juvenal, in its final edition, contains a footnote on the etymology of vegetarian. To be specific, it refers to an address he had given, which was issued as a pamphlet, titled What is Vegetarianism? I have not had any luck tracking down a copy of this; it is just possible that it is included in the collection of essays, Plain Living and High Thinking (see here), but I have not been able to track down a copy of that, either. (Suggestions would be welcome.) Only one library lists it in OCLC, I suspect because others catalog it differently, perhaps because it it's in a box with other Vegetarian Society ephemera. Still, it is possible to piece together much of it from quotations in the Mar. 1907 Vegetarian Magazine and a note by William E. A. Axon in the Christmas 1909 Notes & Queries (snippet only in GB; note that he says that as of then the word had only been traced back to 1845, just before the Society's founding).

The name was born with the Society. [...] No lexicographer has learnt our secret, ‘fruit and farinacea’. The vulgar error that we devour a wheelbarrow load of cabbages at a meal is fostered by definitions like these:

[Here everyone omits Mayor's inventory of “wrong” definitions from various lexica, which is too bad, since that is just the sort of thing this blog is all about.]

Would you be surprised to learn that as Vegetarians, looking at the word etymologically, not historically or in the light of our official definition, we are neither required to eat all vegetable products, nor vegetable products only, nor even vegetable products at all? Far from committing us to abstain from milk and eggs, the name derives its connexion with diet exclusively from the definition given to it by our Society.

When librarian means an ‘eater of books,’ antiquarian ‘an eater of antiques,’ even then vegetarian will not, cannot, mean ‘an eater of vegetables.’ Your learned townsman, my old friend Mr. Roby, has cited many nouns substantive and adjective ending in arius = Engl. arian. All of these are derived from nouns substantive or adjective, none from verbs. Prof. Skeat was misled by a borrowed definition. Antiquus, ‘ancient’; antiqua, ‘antiques’; antiquarius, ‘one who studies, deals in, has to do with, antiques an antiquary or antiquarian.’ So vegetarius, ‘one who studies, has to do with, vegeta.’ What vegetus means you shall hear from impartial lips :—

Vegetabilis is not used in good Latin at all. Cicero's word for plants is gignentia.

‘Vegetus, whole, sound, strong, quick, fresh, lively, lusty, gallant, trim, brave; vegeto, to refresh, recreate, or make lively, lusty, quick and strong, to make sound.’ Thomas Holyoke, ‘Latin Dictionary,’ London, 1677.

Ainsworth adds to the senses of ‘Vegetus,’ agile, alert, brisk, crank, pert, nourishing, vigorous, fine, seasonable; and renders the primitive ‘vegeo’ to be lusty and strong, or sound and whole; to make brisk or mettlesome; to refresh.

The word vegetarius belongs to an illustrious family. Vegetable, which has been called its mother, is really its niece. Vegetation, vigil, vigilant, vigour, invigorate, wake, watch, wax, augment; the Gr. ὑγιὴς (sound) ; Hygieia, the goddess of health; hygiene, the science of health; all these are more or less distant relatives.

The Vegetarian, then, is one who aims at wholeness, soundness, strength, quickness, vigour, growth, wakefulness, health. These must be won by a return to nature, and the natural food for man is a diet of fruit and farinacea, with which some combine such animal products as may be enjoyed without destroying sentient life.

In his clarification, and in specifically addressing his footnote to Sir Henry Thompson's work on diet, and Eduard von Hartmann's essay “Was sollen wir essen?” 'What should we eat?', Mayor is also addressing an issue which would be framed in modern terms as the difference between vegetarians and vegans. His opponents claim that vegetarians, transparently eaters only of foods with vegetable origins, are deceptive when they also eat animal protein like eggs or milk. So, there is position to be won by showing that vegetarian actually refers to a healthy diet in which those are permitted. (This being before it was clear how one might manage to get complete protein without them.) This same idea is presented by Josiah Oldfield in reply to two articles by Thompson and he gives a similar derivation from vegeto 'invigorate'. Eustace Miles rejects the name, since animal protein is needed for his athlete's vegetarian diet. Henry Salt hedges his bets a little:

Mind, I am not saying that the originators of the term “vegetarian” had this meaning in view, but merely that the etymological sense of the word does not favour your contention any more than the historical. (The Logic of Vegetarianism, p. 5)

(In other words, he goes one step beyond the argument that etymology exposes the true meaning of a word, because it does so even when the coiners did not know or intend it.)

In August, 1907, the Third Universal Congress of Esperantists was held in Cambridge. Mayor (then 83) took advantage of the opportunity to learn enough of the language to deliver a speech in Esperanto on the last morning (apparently he addressed them at other times in English that had to be translated). The Times (Mon., Aug. 19, 1907) reported:

Professor J. E. B. Mayor, professor of Latin at Cambridge, addressed the congress amid a scene of the greatest enthusiasm. He said that in their meetings miracle followed miracle, and he had ceased to be astonished at the mutual comprehensibility of all nations. It had come to be plainly seen that their Esperanto Congresses had resulted in the discovery of a new international nation, of which Dr. Zamenhof was the Christopher Columbus. They had witnessed a new Pentecostal festival, as shown by the different nationalities there represented. Professor Mayor proceeded to say he considered it a great mistake for people to suppose that the learning of Esperanto would interfere with the study of other languages. He was convinced that if a child of five learnt Esperanto he would afterwards learn with ease French, Latin, German, &c. Esperanto was, in fact, the lernigilo for all other languages.

See also here and here. I wonder whether a copy of this speech survives someplace.

For more information on Mayor, see the DNB, the obituary by J. E. Sandys in The Classical Review, the “Memoir” in Twelve Cambridge Sermons, and John Henderson's Juvenal's Mayor: the Professor who Lived on 2^d a Day. (I do not agree with the Wikipedia that this last portrait is "unsympathetic," though it is indeed "idiosyncratic." It aims to strike some balance between Mayor as a useless old kook and ignoring his quirks. See also the review of it by one of Henderson's students, Susanna Morton Braund, who is herself a vegetarian and an editor of Juvenal.) Henderson has also edited a version of Mayor's Juvenal, adding commentary on the commentary. Someone should track down a copy of the Catalogue of the Library of J. E. B. Mayor, Deceased, Comprising Upwards of 18,000 Volumes of Books and get it started in LibraryThing's Legacy Libraries project.

Mayor's predecessor as president of the Vegetarian Society was Francis W. Newman, who is best remembered today for holding less orthodox religious views than his brother, John Henry, Cardinal Newman. (There was a third brother, Charles Robert, who was an atheist and a hermit. The Grammar of Assent sums up the situation, “Thus, of three Protestants, one becomes a Catholic, a second a Unitarian, and a third an unbeliever.”) Francis was Professor of — Latin! — at University College, London. (Charles Kingsley, Cardinal Newman's adversary in the debate on Catholicism and Truth which sparked, and is given in an appendix to some editions of, Newman's Apologia, had the same tutor at Cambridge as Mayor, Dr. Bateson.) Professor Newman was a polymath, writing on mathematics as well as religion, philology and vegetarianism. (See the bibliography here.)

Newman translated some English works into Latin, as part of a scheme for facilitating teaching the language:

• Hiawatha:

  Juxta ripas Aequoris Maximi,
  Lacûs latissime relucentis,
  Nocomidis stabat tugurium,
  Nocomidis e Lunâ genitae.
  Nigra surgit pone silva,
  Atrâ contristata pino
  Atque abiete nucamentis squameâ.
  Clara jactatur in froute unda
  Praeter ripam Lacûs Maximi,
  Unda aprica, late relucens. (p. 22)

• Shorter Translations of English Poetry into Latin Verse, such as [15] “Erin's Days of Old”:

  Tempus Ierne revocet veterum,
  Prava priusquam sua progenies
  Infidè proderet ipsam:
  Quum colli déçus aurea torqnis,
  Derepta superbo invasori,
  Malachaeum laudibus auxit;
  Regesque sui, viridi elato
  Panno, miniâ fronde Quirites
  Ducebant per fera bella;
  Necdum regia nostra maragdus
  Maris Hesperii gemma refulsit
  Tempora circum peregriui. (p. 45)

  Note how the philologist cannot help inserting a footnote proposing that Curaidhe 'knights' and Quirites must be cognate, an idea that he also picks up in Regal Rome and which gets blasted by Donaldson here. Curaidh seems to be from a root *k̂ū-ro-s 'strong' and cognate with κύριος and शूर.
   
• or [61] “Peace After War”:

  Nobis hiems morosa tandem splendida
  Evasit aestas sole sub Ebŏrāceo;
  Nubesque cunctae, quae domum obscuraverant,
  Evanuere, penitus immersae mari. (p. 147)

• Robinson Crusoe (Rebilius Cruso; as much a retelling in Latin as a strict translation, and so actually missing most famous passages):

  209. Tamen neutiquam satiata est mea cupiditas. Ad cocos nuces demetendas falculam illam mecum apportavi; scalas novas ipsis in hortis relinquebam. Dum autem infra incedo, ananassas video multas, (mala pïnea vulgo nos vocamus): nunquam ego anteà has animadverti. Jam intelligo et plurimas esse et maximas, paene ex arenis cum cactis nascentes. Unam illicò vindemiavi, nec abstinui quin grande frustum comederim. (p. 55)

He prepared a text of the Iguvine Tables with interlinear latin translation.

Of Newman's translation of the Iliad, Matthew Arnold wrote, “while for want of appreciating the fourth, [Homer's] nobleness, Mr. Newman, who has clearly seen some of the faults of his predecessors, has yet failed more conspicuously than any of them.” Newman replied with Homeric Translation in Theory and Practice and Arnold rejoined.

Newman wrote a Handbook and Dictionary of Modern Arabic, both avoiding the Arabic alphabet. He produced a number of monographs on Berber languages (I am not qualified to say how these compare to the ones listed recently at Jabal al-Lughat):

• “Outline of the Kabail Grammar.” West England Journal of Scientific Literature, 1836. (Listed in Berber bibliographies here and here.)
• “Essay towards a Grammar of the Berber Language,” West of England Journal 1.5 (January 1836): 161-84.
• “On the Berber Language of Mount Atlas, generally supposed to be that of the ancient Mauritanians.”
• “Of the Structure of the Berber Language.”
• “A Grammar of the Berber Language.”
  This ought to be online, but the necessary volume (6) of Zeitschrift für die Kunde des Morgenlandes didn't get scanned for some reason.
• “Berber Languages.” (uncredited).
• “The Narrative of Sidi Ibrahim ibn Muhammad el Messai el Susi.”
• “Wörterbuch des Dialektes der Auelimmiden.”
• “Notes on the Libyan Languages.”
• Libyan Vocabulary.
• Kabail Vocabulary Supplemented by the Aid of a New Source. (OCLC).

Newman's solution to the naming problem was V E M ('vegetables, eggs, milk'), suggested to him by his friend Thomas Jarrett, Professor of Arabic at Cambridge and then Regius of Hebrew. Of Jarrett, Edward James Rapson, Professor of Sanskrit at Cambridge, writing in the DNB, says:

As a linguist, Jarrett was chiefly remarkable for the extent and variety of his knowledge. He knew at least twenty languages, and taught Hebrew, Arabic, Sanskrit, Persian, Gothic, and indeed almost any language for which he could find a student. He spent much time in the transliteration of oriental languages into the Roman character, according to a system devised by himself; and also in promulgating a system of printing English with diacritical marks to show the sound of each vowel without changing the spelling of the word. (Vol. 10, p. 690)

Jarrett's New Way of Marking the Sounds of English Words Without Change of Spelling is online.

Newman sported the timeless look of a center part and long scraggly gray beard. For more information on him, see the DNB, the memoirs here, and the website of the Francis Newman Society.

Mayor's successor as president was, I believe, Ernest Bell, one of the sons of the publishers George Bell & Sons, and, as far as I know, not otherwise relevant to this post.
