The Orbis Sensualium Pictus

When it is remembered that this work is not only an educational classic of prime importance, but that it was the first picture-book ever made for children and was for a century the most popular text-book in Europe, and yet has been for many years unattainable on account of its rarity, the wonder is, not that it is reproduced now but that it has not been reproduced before. But the difficulty has been to find a satisfactory copy.

Many as have been the editions, few copies have been preserved. It was a book children were fond of and wore out in turning the leaves over and over to see the pictures.
