The title-page vignette shows Poseidon and an allegorical female flanking the Portuguese coat of arms; behind them are a row of columns topped by Muses and the ocean, with a tall ship approaching and seagulls. On the first page, the half-page vignette shows three putti holding navigational tools at the lower left; at the right are two tall ships and a castle (the Torre de BelÃ©m?); at the top of the semicircular frame is the sun. Outside the frame, two putti supply wind to move the ships. The 58 diagrams demonstrate how to calculate latitude at sea; each shows the zenith and the globe with meridians and compass directions, plus one other factor (e.g., the position of the sun, moon, or a star) that is required to calculate the latitude. Among the stars used are the North Star, Procyon (the brightest star of Canis Minor), Rigel (Orion constellation), Spica (Virgo constellation), Aldebaran (Taurus constellation), Castor (Gemini constellation).Mata (d. 1809) taught navigation in Lisbon and wrote several other handbooks for pilots.*** Not in InnocÃªncio; cf.
