This composition is a six part motet for the first published in 1545 and has a subtitle ‘Déploration de Lupus’. We saw and already mentioned in this Requiem-survey site several lament/deploration settings: Josquin des Prez for Ockeghem (1497) ; Nicolas Gombert (c.1521), Jheronymus Vinders, for Josquin (1521) ; Certon for Claudin de Sermisy (1562) ; Jacob Vaet for Jacobus Clemens (1556) ; Jacob Regnart for Jacob Vaet (1568) and there are others not mentioned falling out of the scope of this Requiem site. The term Déploration is international accepted to define compositions inspired on the death of a composer. This motet ‘Eheu dolors/ Requiem aeternam/Déploration de Lupus’ is written by Josquin Baston (c.1520-1576) probable at the occasion of the death of LUPUS Hellinck (c.1496-1541) in 1541 in Bruges or of the Death of Joahnnes Lupi in 1539. Lupus Hellinck was choirmaster at Notre Dame in Bruges from 1521 to 1523, and choirmaster at St. Donatian in Bruges from 1523 to his death in 1541.
On the other hand this Lament could be written on the occasion of the Death of Johannes Lupi – Jehan Le Leu - (1506-1539) who worked and died in Cambrai (Kortrijk). It is said and argued Josquin Baston was one of the known pupils of Johannes Lupi. Johannes Lupi was among others from 1527-1537 with some intervals Chapelmaster in Cambrai. He died at young age. In the literature Lupus is mentioned as the most possible dedicatee. This motet by Baston is written for six voices (CCTTBB). In his 6-part lamentation on the death of the above mentioned 'Lupus' the two middle voices (TT) repeat the Gregorian Introit plainchant Requiem aeternam - out of the rite Missae Pro Defunctis Liber Usualis p. 1807 - in canon six times with different counterpoints. In different sources this Lamentation has been found. P. Ulhard in 1545 published this lamentation, Ulhard, Concentus 8, 6, 5 & 4 vocum, Augsburg, 1545 and is now preserved in Paris. This Lament has been reprinted in Maldeghem's Trésor, 1876 XII – 142. The original manuscript probably belonging to the famous Falkenstein collection is since 1894 preserved in Paris at Bibliothèque du Conservatoire de Paris.

This Confitebor tibi is an old Responsorium. There are about 138 Responsoria de Officium Defunctorum, Responds from Office of the Dead known and used during centuries in the Office of the Dead. They are all well ordered, this is number 118. But Josquin Baston used the belonging Versicle ‘Et eripuisti’ number 90 too. The use of all Responds vary per region and they were used all over. Europe. This Respond is in use in Otto of Riedenburg’s Pontifical-ordinal, but be aware these series are absolutely exceptional and used in the German and Austrian region in which Josquin Baston worked. This motet is written by Baston for five parts and it was originally published by Scotto and by Gardano, both printers in Venice in 1549 in Primo libro de motetti a cinque voci da diversi eccellentissimi musici composti et non piu stampati, novamente posti in luce, et con somma diligentia coretti.
