Wooden-columned mosques constitute a major structural group in Turkish mosque architecture. Inspired by the abundance of forestation in the region in which they were built, the mosques that made use of wood boasted of rich architectural ornamentation. It is the aim of this study to offer a presentation of Beyşehir Eşrefoğlu Mosque, one of the wooden-columned mosques that were widely constructed in the Anatolian Selçuk Era, taking their place in Anatolian Turko-Islamic architecture. A product of the local master builders of its time, the structure was included in UNESCO’s List of Provisional World Heritage Sites. In this context, the paper will describe the characteristics and elements of the layout of the Beyşehir Eşrefoğlu Mosque, its structural system, roof structure, and the distinctive features of the materials and adornments used.


There are few branches of science so indelibly associated with the second half of the last century as that highly-specialised study of the compounds of carbon, which is commonly called organic chemistry. The marvellously rapid development of this branch of chemistry will ever remain one of the greatest monuments to the enthusiasm and industry of scientific workers. Amongst the master-builders of this imposing edifice, one of the most conspicuous was Johannes Wislicenus, who, over a period of more than forty years, devoted his great natural gifts and extraordinary energy to this work of construction. Although in 1853, at the early age of 18, we already find Wislicenus acting as assistant to Heintz, then Professor of Chemistry in the University of Halle, his further progress to academic distinction did not proceed on the stereotyped lines usually followed by those who succeed in gaining access to the select professional caste of the German universities. Wislicenus’ early life is, in fact, of special interest, taking us back as it does to a time when liberty and freedom of speech were ideals for which serious sacrifices had to be made even in the countries of Western Europe.

Historians have long recognized the central role of debt and credit for producers, retailers and consumers in the later eighteenth and early nineteenth centuries. Against a background characterized by persistent shortages of specie, limited banking facilities and erratic transport mechanisms, the speculative impulse that fed the expanding economy drew sustenance from a proliferation of instruments of private credit — notably bills of exchange, promissory notes, and accommodation bills — which, together with an increase of trade credit to retailers and their customers, served to promote and intertwine the industrial, commercial and consumer revolutions. ‘At any one time any business owed and was owed many goods caught up in the process of exchange’, Julian Hoppit observes of the later decades of the eighteenth century. ‘All businessmen were creditors and all businessmen were debtors.’ As trade and manufacture increased in English towns and cities, extended chains of indebtedness multiplied the economic links both between individual producers, retailers or consumers and among these sectors of the economy. Thus in Lancashire innkeepers were the debtors of maltsters, brewers and wine merchants, but were the creditors of shopkeepers, who in turn extended webs of consumer credit to sawyers and carpenters, artisans typically indebted (in their capacity as producers) to the master builders for whom they laboured in Liverpool's shipyards. Based on personal faith rather than tangible securities, these varied forms of private credit were notoriously unstable. Broad-based financial crises fuelled by the failure of private credit became commonplace in the last three decades of the century, and persistently disrupted economic life into the Victorian period.
