The planetary squares had disseminated into northern Europe by the end of 15th century. For instance, the Cracow manuscript of "Picatrix" from Poland displays magic squares of orders 3 to 9. The same set of squares as in the Cracow manuscript later appears in the writings of Paracelsus in "Archidoxa Magica" (1567), although in highly garbled form. In 1514 Albrecht Dürer immortalized a 4×4 square in his famous engraving "Melencolia I." Paracelsus' contemporary Heinrich Cornelius Agrippa von Nettesheim published his famous three volume book "De occulta philosophia" in 1531, where he devoted Chapter 22 of Book II to the planetary squares shown below. The same set of squares given by Agrippa reappear in 1539 in "Practica Arithmetice" by Girolamo Cardano, where he explains the construction of the odd ordered squares using "diamond method", which was later reproduced by Bachet. The tradition of planetary squares was continued into the 17th century by Athanasius Kircher in "Oedipi Aegyptici" (1653). In Germany, mathematical treaties concerning magic squares were written in 1544 by Michael Stifel in " Arithmetica Integra", who rediscovered the bordered squares, and Adam Riese, who rediscovered the continuous numbering method to construct odd ordered squares published by Agrippa. However, due to the religious upheavals of that time, these work were unknown to the rest of Europe.
