I am pleased to announce that a work that two colleagues--Chiara Bariviera and William L. North--and I have worked on for a long time is now out! Luis Gómez, The Floods of the Tiber with Additional Documents on the Tiber Flood of 1530, Translated by Chiara Bariviera, Pamela O. Long, and William L. North (New York: Italica Press, 2023). Translated from Latin to English, it is Gómez's detailed history of Tiber River flooding, including the 1530 flood which he experienced.  


In press is a synthetic work on the history of technology--Technology in Mediterranean and European Lands, 600-1600 (Baltimore: Johns Hopkins University Press, forthcoming).


Two additional projects are as follows: 

First, I and  architectural historian Ann Huppert, are jointly researching and writing a book on the construction of the Gesu' in Rome, a huge church constructed between 1568 and 1580 in the center of the city. Our work is based on numerous archival documents, including a detailed building account that show payouts to workers from the beginning of the work - the foundations - to the end, including the roof and facade.. 


Second, I am writing a book about the lure of machines and machine books from the late 15th century to the early 17th - from Leonardo da Vinci to Vittorio Zonca. In one aspect of this work, medieval historian of science Elly Truitt and I are writing a joint article on Leonardo's mechanics and the medieval science of weights
