Abstract:
It recently emerged that two bronze ‘doorknobs’ in the Rijksmuseum collection, decorated with Tritons blowing conch shells and with inlaid silver discs, came from the renowned collection of the Amsterdam merchant and burgomaster Nicolaes Witsen. They were listed in 1728 in the catalogue of the sale of his estate (in the Antiquiteyten section) and appear in an engraving in the third, enlarged edition of Witsen’s Noord en Oost Tartaryen of 1785. It was also possible to establish that they were not, as had long been thought, sixteenth-century objects, but Roman appliques dating from the first century AD. The pair probably came from a litter used to carry the body of a deceased to its burial place. The two pieces were recently transferred to the National Museum of Antiquities in Leiden, where they have been reunited with other antiquities from Witsen’s collection.

Abstract:
In a collection of essays concerning the inevitably diverse vicissitudes of the representatives of that phenomenon collectively known as ‘the Company's servants,’ the inclusion of Nicolaas Witsen may come as a surprise. In our democratic age, he undoubtedly would have termed himself a ‘servant’ of the Dutch East India Company; in his own, more hierarchical times, he will have considered himself one of the Company's masters, as indeed he was. Whatever the powers of the Heren XVII may actually have been, Witsen for many years was one of the directors of the Amsterdam Chamber, the Company's most powerful division, and one of Amsterdam representatives to the bi-annual assembly which actually directed the Company's affairs at home, and tried to do so abroad, in its far-flung commercial empire, where other servants often held far greater, and less controlable power.

Abstract:
The current infrafamilial taxonomy of the Iridaceae recognizes four subfamilies; Isophysidoideae (1: 1); Nivenioideae (6: ca. 92), Iridoideae (29: 890), and Crocoideae (29: 1032). Phylogenetic analyses of sequences of five plastid DNA regions, rbcL, rps4, trnL–F, matK, and rps16, confirm most aspects of this classification and the evolutionary patterns that they imply, importantly the sisiter relationship of Isophysidoideae to the remainder of the family and the monophyly of Iridoideae. Subfamily Nivenioideae is, however, paraphyletic; Crocoideae is consistently found nested within it, sister to the core Nivenioideae, the woody Klattia, Nivenia, and Witsenia. This clade is sister to Aristea, which in turn is sister to the Madagascan Geosiris, and then to the Australasian Patersonia. We treat Aristea, Geosiris, and Patersonia as separate subfamilies, Aristeoideae and the new Geosiridaceae and Patersonioideae, rendering Nivenioideae and Crocoideae monophyletic. The alternative, uniting a widely circumscribed Nivenioideae and Crocoideae, seems undesirable because Nivenioideae have none of the numerous synapomorphies of Crocoideae, and that subfamily includes more than half the total species of Iridaceae. Main synapomorphies of Crocoideae are: pollen operculate; exine perforate; ovule campylotropous; root xylem vessels with simple perforations; rootstock a corm; inflorescence usually a spike; plants deciduous. Four more derived features of Crocoideae are shared only with core Nivenioideae: flowers long-lived; perianth tube well developed; flowers sessile; and septal nectaries present. The genera of the latter subfamily are evergreen shrubs, have monocot-type secondary growth, tangentially flattened seeds, and the inflorescence unit is a binate rhipidium. The latter feature unites core Nivenioideae with Aristea, Geosiris, and Patersonia, which have fugaceous flowers and, with few exceptions, a blue perianth. Molecular-based phylogenetic trees using sequences from five plastid DNA regions now show discrete generic clusters within Crocoideae and Iridoideae, the foundation for the tribal classification. The five tribe classification of Iridoideae, initially based on morphological characters and subsequently supported by a four plastid DNA region sequence analysis, continues to receive support using additional DNA sequences. Application of molecular clock techniques to our phylogeny indicates that the Iridaceae differentiated in the late Cretaceous and diverged from the next most closely related family, Doryanthaceae circa 82 mya, thus during the Campanian. The Tasmanian Isophysis is the only extant member of the clade sister to the remainder of the Iridaceae, from which it may have diverged 66 mya, in the Maastrichtian. The generic phylogeny shows the proximal clades of the family are all Australasian, which corroborates past hypotheses that the Iridaceae originated in Antarctica-Australasia, although its subsequent radiation occurred elsewhere, notably in southern Africa and temperate and highland South America at the end of the Eocene or later.

Abstract:
Abstract After briefly exploring various conceptions of the Europe-Asia divide, the paper observes how one panoramic image of Tobol’sk – a Russian town in the heart of Eurasia – traveled through several early modern manuscripts. While it is well known that the Dutchman Nicolas Witsen had a hand in the production of the western European texts that featured the Tobol’sk panorama and that the Tobol’sk panorama Witsen reproduced was a copy of one by the Siberian cartographer S.U. Remezov, this paper wonders if amateurish panoramas by Nicolaas Witsen may have inspired Remezov’s Tobol’sk panorama. While questions about this panorama’s history and textual “travels” remain, this preliminary inquiry and speculation remind us to be attentive to unexpected dynamics and modes of early modern transmission.

Abstract:
Summary This contribution studies the cessio bonorum of painter Rembrandt van Rhijn in relation to the relevant rules and institutions of Amsterdam. In the Rembrandt case the procedural rules on the cessio bonorum were followed to a large extend. In regard to the beweysinge, a few weeks before the application for the cessio, it seems more convincing that it should be interpreted as a promise than as a conveyance of the house he owned. This new perspective on the beweysinge, however, does not alter the fact that it seems likely that there was a conflict between the Orphans Chamber (serving the interests of Titus) and the Insolvency Chamber (serving the interests of the creditors, and among them especially the former burgomaster Cornelis Witsen). Arguments for this are derived from: 1) the new bylaw issued by the Orphans Chamber shortly after Rembrandt’s application for the cessio, 2) the appointment of the renowned lawyer Louis Crayers as guardian of Titus (instead of Jan Verwout), and 3) the position of Titus’ preferential claim in the concursus creditorum. Crenshaw has stated that this conflict was decided by the personal influence of Cornelis Witsen. This contribution defends that Witsen only could enforce the sale of the house because of the institutional and political power structures within the city government. Witsen belonged to the powerful reigning faction of Cornelis de Graeff, whereas the majority of the officials in the Orphans Chamber belonged to the ‘political opposition’. In the end it was especially Witsen who profited from the sale (at the expense of Titus).

Summary This contribution studies the cessio bonorum of painter Rembrandt van Rhijn in relation to the relevant rules and institutions of Amsterdam. I would first and foremost like to thank professor Eddy Put (KU Leuven), for repeatedly reading my drafts and providing me plenty of useful references and advice. Gerrit Vanden Bosch, Marie-Juliette Marinus, and Jos Van den Nieuwenhuizen kindly answered my many questions, and, needless to say, all the possible flaws are on my own responsibility. In conducting this research, I was supported by the Hitotsubashi University Foundation (Japan). In the Rembrandt case the procedural rules on the cessio bonorum were followed to a large extend. In regard to the beweysinge, a few weeks before the application for the cessio, it seems more convincing that it should be interpreted as a promise than as a conveyance of the house he owned. This new perspective on the beweysinge, however, does not alter the fact that it seems likely that there was a conflict between the Orphans Chamber (serving the interests of Titus) and the Insolvency Chamber (serving the interests of the creditors, and among them especially the former burgomaster Cornelis Witsen).

Abstract:
Witsenia is a monospecific genus of the putatively basal group, the woody Iridaceae. This upright iris has extremely long black and yellow flowers ( see fig. 1) that are thought to have been pollinated by an extinct Sunbird. The role of the unusual black floral colouration is investigated as this colour is seldom associated with bird pollination. This plant typically exists in discreet and restricted populations in wet habitats in the South Western Cape (South Africa). The restricted nature of the plant is peculiar as it occurs in either low or high altitudes, yet appears to be extremely sensitive to altitude. Popular belief suggests that Witsenia maura occurs in the Peninsula only, and results from this study show the Peninsula population to be genetically separate from other populations, reflecting a long term separation. Samples from nine populations are sequenced to investigate haplotypic variation within the species, and dispersal of ancestral populations. This thesis investigates the current knowledge of Witsenia, its ecology, history and distribution. An examination of flowers under UV light reveals the first evidence of UV nectar guides in an ornithophilous flower. Conservation issues are also addressed, and it is established that although small and apparently shrinking due to global warming, populations are nonetheless viable if managed properly. A molecular study of the species and examinination of its variation revealed exceptional haplotype diversity. This diversity can best be explained by swamps acting as refugia during interglacial periods.
