Greece. (c1920). [Geological Maps of] (‘Ap38)Syros and Milos (‘Ap39) Naxos and Amorgos from the series Geological Map of Greece [ΓΕΩΛΟΓΙΚΟΣ ΧΑΡΤΗΣ ΤΗΣ ΕΛΛΑΔΟΣ]. Athens: Geological Service of Greece. Published during the late 19101s and 1920s. No dates on maps. Flat colour lithographs at 1:300,000 scale, 52 x 34 cm). Entirely in Greek with light pencil annotations translating the map titles. Library stamps in lower right corner, otherwise, clean. Bright and in very good condition.

Sold as a pair as island of Paros is split between them and the pair form a pleasing group visually. Other islands covered are: (‘Ap38) Kythnos, Serifas, Folegandros, Sikinos,  west half of Paros (‘Ap) Mykonos, east half of Paros, and Ios.

These sheets are from the first official geological series of Greece, published by the Geological Service of Greece (then part of the Ministry of National Economy) during the late 1910s and 1920s. They represent a critical transition where Alfred Philippson’s German research was officially "Hellenised" and expanded for Greek national use. They are quarter sheets of the four folding geological maps of the same scale published by Alfred Phillipson (1864-1953) in Beiträge zur Kenntnis der Griechischen Inselwelt, [Contributions to the knowledge of the Greek islands] Gotha, 1901.

The coordinates used appear to be based on a prime meridian passing through Athens.
