This pencase is a rare signed example of metalwork from the reign of Sultan Mahmud I (r.1730-54). Fortunately, the artist Ismail b. Mehmed is recorded and his works documented. For his signature, please see Kürkman 1996, p.106. Inside the lid is an incised calligraphic composition which includes the names of the so-called 'Seven Sleepers' mentioned in the Qur’an, Surat al-Kahf. Their names, which have talismanic values are Yamliha, Makthalina, Mislina, Marnush, Dabarnush, Shazanush, Kafashtatayyush and their dog Kitmir. This inscription is beautifully composed in the shape of the star of Solomon (mohr-i Sulayman) in the centre. For comparable applications of the names of the 'Seven Sleepers' on Ottoman silver pen-cases please see ibid. p.82. This divit is of further interest as it bears stylistic resemblance to some silver pen-cases from the period of Sultan Ahmed III (r.1703-30), illustrated in Kürkman 1996, pp.152-5.
