Theodori Kerckringii doctoris medici spicilegium anatomicum : continens observationum anatomicarum rariorum centuriam unam : nec non osteogeniam foetuum : in qua quid cuique ossiculo singulis accedat mensibus : quidve decedat & in eo per varia immutetur tempora, accuratissimè oculis subjicitur
A Latin anatomical treatise by Theodor Kerckring, published in Amsterdam in 1670 by Andreas Frisius, aimed at physicians and anatomists studying fetal bone development. The pictures are white-ground copper engravings, probably by Abraham Blooteling, showing a skeleton standing in full front and side views with numbered fetal bones and skull details placed around it. A designer might take the clean, diagrammatic line work and the orderly plate layout with labelled figures.
