An Ottoman Calendar, 19th Century (Osmanlı Takvim-i Devri Daim)
–-----
Perpetual almanac. 17th-century illustration of a perpetual almanac (a type of calendar) devised for the English county of Staffordshire, and presented in the form of a clog almanac, which consisted of a log of wood with four edges, shown here as four vertical blocks. Each notch represents a day, with large notches representing a week. Each of the edges shows a period of three months, with the whole representing a year. The symbols represent religious festivals and phases of the moon. The dedication by English naturalist Robert Plot (1640-1696), first Professor of Chemistry at the University of Oxford, and the first keeper of the Ashmolean Museum, is to English antiquary Elias Ashmole (1617-1692). Artwork from Plot’s ’The Natural History of Staffordshire’ (1686).

DELL’ ALMANACCO PERPETTUO1676Splendid WoodcutsRare BookVenice, Italy, 1676. Exceedingly rare early edition of this scarce intriguing almanac. Many woodcuts, detailed and delightful. Medicine meets mysticism, science mixes with sorcery. Odd and intriguing. In darkened vellum binding, worn, missing corner, and the binding is more of a portfolio as the pages, bound together, slip right out, not attached anymore. Some repair work was done on this book long ago, not particularly skillful work especially at the spine. Pages patched up, mostly at the start, and some newer endpapers. Missing the main title page, there is a title page further in, two books bound as one - volume begins with a lengthy index (heavily repaired), a few prefaces, then p.1 is the beginning of the monthly almanac with small woodcuts. Missing p.81-p.84, p.151-p.155, p.385/6, & p.395/6, ends properly on p.516 then comes a title page and new pagination ending on p.142. Some browning, toning, staining, and worn edges. 4 x 7 inches.
