December 8 – Sea-centaurs

Ichthyocentaurs are winged creatures, half-fish and half-horse. Depicted in classical Greek art, they are also referred to as sea-centaurs.
This illustration of an ichthyocentaur, playing a lute, is featured on a map of Scandinavia by cartographer Abraham Ortelius in our 1575 edition of Theatrum orbis terrarium (TypNAn.B75RO).
What a delightful creature to learn about and its name (ichthyocentaur). And evidently it's musical!
