The 1574 Venice edition of Roman philosopher Macrobius' Neo-Platonist work [Commentarii] In somnium Scipionis and Saturnalium.
The work is particularly famous for its world map (on page 144), which presents a geographically similar map to the original woodcut used in Brescia in 1483. This map, adorned with cherubic wind heads (an addition that first occurred in the woodblock of the 1500 Venice edition), is a significant example of early cartography.
As noted by Shirley:
The inhabited world north of the Equator is balanced by a southern continent and divided from it by water. Among the roughly 150 manuscripts recorded by Destombes dating from 1200 to 1500 AD nearly 100 contain a simple map illustrating Macrobius's theories.
Macrobius' commentary on The Dream of Scipio (Somnium Scipionis), which makes up the majority of the sixth book of Cicero's De Republica, is perhaps the most well-known passage since, unlike the rest of the work, it has come down to us practically intact. It is Macrobius' Commentarii that allowed the dissemination of Cicero's text.
Macrobius Ambrosius Theodosius was a prominent Roman philosopher and commentator whose works bridged the classical and medieval worlds. His Commentary on the Dream of Scipio and the Saturnalia are vital texts for understanding the transmission of classical knowledge through the Middle Ages and into the Renaissance. The Somnium Scipionis interprets a dream vision from Cicero's De Republica, focusing on cosmology and virtue, while the Saturnalia presents a rich tapestry of Roman customs, beliefs, and intellectual debates.
