Trajan (Marcus Ulpius Nerva Traianus) was born on this day (or close to it) in the year 53. Emperor of Rome from 98 to 117, he was a successful general and civil administrator well known for his architectural projects. In addition to his many imperial portraits, he left to Rome the forum bearing his name, the colossal frieze-encircled column depicting his military exploits in what is now East-Central Europe, and the Markets of Trajan. 
An innovative urban mixed-use development in the heart of the city, the Markets made extensive use of brick, an inexpensive but versatile material. The curved facade was the first of its kind in the city and has inspired commercial buildings ever since.
