18th century Ilustration of the Moon after Grimaldi & Riccioli

A map of the Moon's surface of the moon according to Grimaldi and Riccioli. with four diagrams of the phases in the corners. The principal 'seas', mountain ranges and craters are labelled following the Jesuit nomenclature first established in Bologna in the mid-17th century. This plate was issued in Pierre-Charles Le Monnier’s Institutions astronomiques, a widely used French astronomical manual, intended to make contemporary celestial science accessible to students and amateur observers. Francesco Maria Grimaldi (1618-1663) and Giovanni Battista Riccioli (1598-1671) were Jesuit astronomers working in Bologna who produced one of the earliest systematic maps of the Moon. Their nomenclature, naming lunar features after philosophers, scientists, and theologians, was first published in Riccioli’s Almagestum Novum (1651) and formed the basis for lunar mapping for centuries. Many of the crater names they coined are still in use today.
