Perhaps overshadowed by the great 1495 Aristotle edition of Aldus Manutius or perhaps by the 1640 establishment of the Imprimerie Royale, this imposing four volume edition of Aristotle in 1639 has perhaps been unfairly neglected. Aldus had reintroduced Aristotle's Greek text to the Western world by way of the printing-press, but his Greek typeface is said to have been based on the handwriting of his friend Marcus Musurus, with its crabbed and unusual ligatures. This edition sets forth both Greek and Latin texts in parallel columns, filling an important historical and scholarly need. Aristotle was not only one of the greatest classical philosophers, but his method came to be seen as underlying all branches of ancient knowledge and modern thinking. To Aristotle the universe consists of substances and the relations between them, unlike the Platonic world of ideas.[PMM]
