1720 (undated) 21 x 12 in (53.34 x 30.48 cm)
This is a page from a stunning 18th century manuscript treatise on navigation. The teatise, Introdusione alla sfera e alla Geografia Moderna, alas, is incomplete. Definitions of geographical terms critical to navigation are detailed, such as continent, island, peninsula, gulf and strait. Each definition is followed by a diagram of the term and an example. Each diagram includes the geographical term in question as well as ships on the sea and birds in the sky. Definitions 29-38 are given in full on the recto and verso of this page, along with the beginning of definition 39. All text is in Italian. We have provided a date of 1720, but this is merely conjecture. Based upon the paper and style, it is reasonable to assume this was drawn between 1650 and 1790.
Good. Water stains upper right. Italian manuscript text on recto and verso.
