The Tammar Luxoro Atlas, or Atlante Luxoro, is an anonymous collection of Italian portolan charts from the early 15th century, currently held at the Biblioteca Civica Berio in Genoa, Italy.
The author is unknown, although believed to have been made by Francesco de Cesanis of Venice.
The Luxoro Atlas was once believed to originate from the early 14th century, and sometimes said to have been authored by the Genoese cartographer Pietro Vesconte.
[1] However, according to more recent scholars, the Luxoro Atlas was probably made by the Venetian cartographer Francesco de Cesanis, probably a little time before 1421.
The eight sheets are separate nautical charts, together covering the "normal portolan" range.
