17th century drawing of the human skull from a Dutch anatomy textbook
This public domain image of a human skull is a drawing that was included in a 17th century Dutch medical textbook by Govard Bidloo. As you can see, the skull is presented from several angles so viewers can observe the bone structure. The letters adorning each bone correspond with the Latin name of the bone, for quick reference and study.
Because the text was published in 1690, it is in the public domain.
