Decem et Tria Loca Confoederatorum Helvetiae.

A fine antique copper engraved sheet with 13 copper engraved views of the original 13 Cantons of the Swiss confederacy from the first volume of Braun & Hogenberg's "Civitas Orbis Terrarum." Latin text to verso. First state, part 1. Koln, 1572.
13 views on 1 plate. The views are: Suicia- Schwytz; Sylvania- Underwalden; Tugium-Zug; Glarona- Glaris; Basilea- Basel; Tygurum-Zurich; Civitas Ursina-Bern; Lucerna-Lucern; Ursella-Uri; Fiburgum- Fryburg; Civitas Soluterensis -Solothurn; Shaphusia- Schaffhussen; Appencella- Appenzell.
Each gives the date of joining the confederacy.
Between 1291 and 1512, the 13 original Swiss cantons slowly forged a single alliance, the Old Swiss Confederation, which lasted until 1798. The 13 cantons are illustrated in relatively small views, accompanied by the year in which they joined the Confederation. According to Swiss national legend, the three cantons of Schwyz, Unterwalden, and Uri were the first to pledge their mutual allegiance in what is known as the "Rutli oath", taken in August 1291 on the Rutli meadow on the shores of Lake Lucerne.
Braun's sources date the birth of the Confederation to 9 December 1315, when the original three cantons signed the Pact of Brunnen after the victorious battle of Morgarten against the Habsburgs.

Eleven of the 13 views derive from a single set of sources: the woodcuts from the Schweytzer Chronick of Johannes Stumpff, 1548. Each of those rectangular illustrations in a horizontal format takes up half a folio page: here they have been considerably reduced in scale and, most noticeably, the proportions have been changed. There are no reliably verifiable sources for Zug and Unterwalden; consequently, Zug is erroneously shown by a river instead of the lake at Zug and Unterwalden as a mountain village without distinguishing features (Taschen).

The 'Civitates Orbis Terrarum', or the "Braun & Hogenberg", is a six-volume town atlas and the greatest book of town views and plans ever published: 363 engravings, sometimes beautifully colored. It was one of the best-selling works in the last quarter of the 16th century.
Georg Braun wrote the text accompanying the plans and views on the verso. A large number of the plates were engraved after the original drawings of Joris Hoefnagel (1542-1600), who was a professional artist. The first volume was published in Latin in 1572, the sixth volume in 1617.
Frans Hogenberg created the tables for volumes I through IV, and Simon van den Neuwel created those for volumes V and VI. Other contributors were cartographer Daniel Freese, and Heinrich Rantzau. Works by Jacob van Deventer, Sebastian Münster, and Johannes Stumpf were also used. Translations appeared in German and French.
