The term ‘Mohtasham’ refers to the revered master weaver Hajji Mollah Mohammad Hassan Mohtasham (active circa 1840 – 1885). Mohtasham is known only through a handful of existing signed works and now the term ‘Mohtasham’ is used amongst carpet connoisseurs to describe works produced in Kashan, toward the end of the 19th and beginning of the 20th century, of excellent quality and design, utilising the remarkably velvety kurk wool. For further reading on the master and ‘Mohtasham’ works see Azadi, Siawosch, ‘The Mark of Mohtasham’ , Hali, 2009, Issue 160, pp. 66 – 73, or Bennett.
