This rare 17th-century Greek–Latin lexicon, published in London in 1637, is a monumental folio reference work compiled by John (Ioannis) Scapula, one of the most influential lexicographers of the Renaissance and early Baroque period. Printed by Thomas Harper, this substantial volume represents an important milestone in classical scholarship. Bound in full leather, the book measures approximately 13.75 × 9.5 × 3.5 inches, and combines four major Greco-Latin reference works in a single volume, each with its own title page. The compilation reflects the scholarly ambition of the early modern period and was intended as a comprehensive tool for linguists, theologians, and humanist scholars.
