Janus Dousa Jr. (Latinized from Johan van der Does, also Janus Dousa filius, Janus II Dousa, Janus Dousa the younger, 16 January 1571 - 26 December 1596) was a Dutch classicsscholar, Neo-Latinpoet, historian and the second librarian of the young Leiden University (1593-1596).
Biography
Young years
Dousa Jr., the eldest son and the first of ten children of Janus Dousa (Johan van der Does, Dousa Sr.), was born at Noordwijk but in 1573 his family moved to Leiden, where his father was in command during the second siege by the Spanish army (26 May–3 October 1574). He was taught the classics by his father and at a young age excelled in languages. He was then, for instance, already well versed in writing Neo-Latin poetry. Johannes Meursius called Junior "verum Gratiarum pullum" (a true chick of the Charites). Janus Dousa Jr. concluded his studies at Leiden University in Latin, Greek, Hebrew, Roman law, mathematics and astronomy, with professors Peter Tiara (Petreius Tiara, Pieter Tjeerts, Greek language), Bonaventura Vulcanius, Justus Lipsius, and Petrus Bertius in 1583. He assisted his father in literary studies and library activities. In 1594 he tutored Frederick Henry, Prince of Orange for a short time, when the prince was a student at Leiden University.
In the summer of 1585, Dousa Sr. led an informal Dutch embassy to England to investigate a possible Anglo-Dutch union, later leading to the failed military mission of Robert Dudley, 1st Earl of Leicester and his nephew the poet Philip Sidney to the Netherlands. A small group of Leiden Neo-Latin poets, including Dousa Jr., his friend Dominicus Baudius and Georgius Benedicti Wertelos, visited London in the summer and autumn of 1585 and met with fellow English poets.
Librarian of Leiden University 1593-1596
When his father Dousa Sr. was appointed a member of the Hoge Raad in 1591, Junior assumed the duties of his father as a pro tem university librarian and succeeded him officially on 15 July 1593, at the age of 21, so becoming the second librarian of the young Leiden University. On a two-year journey through Europe including Germany and Poland with two of his brothers starting in 1594 he fell ill and died shortly after his return at The Hague in 1596, at the age of 25.
Reputation
Notwithstanding his young age, Junior was considered a significant scholar, so that his portrait graces the frieze of the Bodleian Library at Oxford. In 1612, Leiden library curators commissioned five portraits of scholars considered outstanding, with Junior alongside his father Janus Dousa Sr., Justus Lipsius, Johannes Heurnius and Henricus Junius.
Leiden University's leading professor Joseph Justus Scaliger mourned the untimely death of his student: «Jamais je n’ai pleuré de mort que lui, mais je l’ai pleuré à bon escient. Il mourait tout en parlant; il ne sentait point de mal. Le pauvre Janus était si bon et si simple! Je pleuray huit jours durant comme une vieille, lorsqu'il fut mort.» (Translation from the French: I have never cried for anyone's death but his, but I cried for him with good reason. He died while talking; he felt no pain. Poor Janus was so kind and simple! I cried for eight days like an old woman when he died.)
During his absence and after his decease, Petrus Bertius stood in for Janus Dousa Junior as the university librarian.

Epigram for the historian Van Meteren, 1585
Latin epigram by Janus Dousa Jr. at age 14 as a tribute contribution to the Album Amicorum presented to the Flemish historian Emanuel van Meteren
Mens mihi in ambiguo utrum tua iussa secutus Inscalpam libro carmina pauca tuo;
An potius nihil hic ausus, metuensque tot inter Obscurum artifices nomen habere viros
Nil scribam, reddamque tibi hoc inglorius Album Nomine denigrare ipse meo veritus:
Sed quoniam tibi maiori parere necesse est, Qui me sis factus paene senex puero,
Effigiem tibi non aliquam aut insignia pingam Maiorum, at male natum hoc Epigramma dabo.
Ergo cape EMANUEL manum monimenta mearum, Ingeniique modo non puerilis opus,
'Mnemostunon filias' aeternum mique tibique,
Dum notus terris sit vetus EMANUEL.
D. EMANUELI DEMETRIO mercatorum doctissimo, amicitiae
paternae caussa scripsi hoc qualecunque Epigramma JANUS DOUSA filius.
Londini Anno 1585. Aetatis vero 14.
—Janus Dousa Jr.
Translation:
While doubting in my mind whether following your orders I'll engrave a few poems in your book;
Or rather not risking anything here, fearing that among so many expert artists I with an obscure name
will write nothing, and return to you this Album as a nobody, worrying that I smirch my name:
But since of course i must obey a senior, you, Who has made a wise old man of me out of hardly a boy,
I'll paint you not some portrait nor coats of arms Of my ancestors, but I'll give you this feeble born Epigram.
Therefore, receive, EMANUEL, the memorials by my hands, and so the work of a nearly childish talent,
A 'Mnemostunon filias' [Greek: A friendship memorial] eternal for me and you,
As long as the old EMANUEL be known throughout the world.
To Mr. EMANUEL DEMETRIUS, most learned of merchants, for paternal friendship's sake
I have written this sort of Epigram, JANUS DOUSA son. London, 1585. Aged 14.

Whom alone heaven's Powers venerate, and [who]
Watches the armies of the Gods with completely painted wings,
Great Parent, because it pleases to divulge your work to the nations,
