Lovely miniature map of northwestern section of the Balkans - present day Slovenia and Croatia with the Adriatic Sea located at the lower left. The map is filled with tiny cities and good detail of the rivers systems. French text on verso. The first pocket version of Ortelius' Theatrum was published by Philippe Galle in 1577 as Spieghel der Werelt. Galle began a new edition with new plates, commonly known as the Epitome, in 1588. Galle's miniature atlas was quite popular, and was published in editions until 1602. From 1583 he gradually introduced a new set of maps, both adding to and replacing the originals. The plates were then passed to Jan B. Vrients, who retouched some of the plates and published the final editions of the Epitome in 1601 and 1602.

A nice impression with light toning and marginal soiling.
