This folio from Walters manuscript W.624 contains a colophon that gives the name of the calligrapher as Muhammad Husayn Zarrin Qalam and the date 142, which is difficult to interpret. Seyller and Brend read it as dated 42 and thus interpret it as the 42nd year of Emperor Akbar's reign, i.e. AD March 1597-March 1598. According to Seyller the vertical stroke that precedes the 42 should be regarded as an extended dot over the nun in the word sana (year). According to Brend the vertical stroke should be read as an alif for ilahi.
