During the reign of Constantine the Great, the Roman senator and poet Publilius Optatianus Porphyrius was sent into exile for crimes unknown. He succeeded in regaining favor and his good name by composing a series of poems in praise of the emperor which looked like nothing else. His poetry was an evolution of the Greek tradition of pattern poetry, but he took it a much more complex level, as Arrigo Lora Totino explains. In an illustrated article, John Stephan Edwards goes through the poetry of Porphyrius, showing the evolution of his craft.
Spanning one-ninth of the earth's circumference across three continents, the Roman Empire ruled a quarter of humanity through complex networks of political power, military domination and economic exchange. These extensive connections were sustained by premodern transportation and communication technologies that relied on energy generated by human and animal bodies, winds, and currents. Conventional maps that represent this world as it appears from space signally fail to capture the severe environmental constraints that governed the flows of people, goods and information. Cost, rather than distance, is the principal determinant of connectivity. For the first time, ORBIS allows us to express Roman communication costs in terms of both time and expense. By simulating movement along the principal routes of the Roman road network, the main navigable rivers, and hundreds of sea routes in the Mediterranean, Black Sea and coastal Atlantic, this interactive model reconstructs the duration and financial cost of travel in antiquity.
The Ancient Theatre Archive: A Virtual Reality Tour of Greek and Roman Theatre Architecture offers photos, panoramas, detailed descriptions, and, in several instances, virtual tours of classical theatre sites across Europe. (Tours require Quicktime to view.) The Met offers a basic overview of the differences between Greek and Roman theatrical architecture. For more theatres and related theatrical imagery, visit John Porter's one-stop catalog of online visual resources, Skenotheke.
Physicist Howard Wiseman has a hobby, history. On his website he has three history subsites, filled with lots of information: 1) Ruin and Conquest of Britain 2) 18 Centuries of Roman Empire 3) Twenty Centuries of "British" "Empires". Especially informative are his many maps. As he says himself: "Drawing historical maps of all sorts has been a hobby of mine since my mid teens. Now I can do it digitally, and inflict it upon the world!"
In my quest to fulfill a jones for antiquity, I came across some Roman Numismatics. There are many great photos of Roman artifacts to be found here. Monetary, military, scroll down, click and scroll some more. It's almost as if ancient Rome has come back to life. (Some art is NSFW)
