Codanus Sinus

CODA´NUS SINUS the sea to the east of the Chersonesus Cimbrorum (Jutland), which, as Pomp. Mela (3.4) states, is filled with islands, all of which belong to the modern kingdom of Denmark. It was therefore the southern part of the Baltic. According to Pliny (Plin. Nat. 4.27) it extended north as far as the prom. Cimbrorum.

One of the ancient names of the Baltic. Mela (iii. 3, 6) represents it as full of large and small islands, the largest of which he calls Scandinavia; so also Pliny (iv. 13).
