  • In the Spanish suited type, the batons are knobly clubs or cudgels and the swords and batons are drawn separately on the pip cards.
  • Cards with Spanish suits are also used throughout the southern part of Italy.
  • In the Italian suited type, used in the northeast of Italy, the batons are straight ceremonial sticks, and on the numeral cards they intersect to form a trellis. The swords are mostly curved and intersecting on the pip cards, though they are straight on many of the picture cards.

Late 16th-century engraving by Jan van der Straet (Stradanus) showing Venetian scholar Flavio Gioja at his desk with a magnetic compass, dividers, an astrolabe, and sailing ships.
  • The Magnetic Compass (Agulha de Marear):
    While maritime pilots relied on larger shipboard compasses—housed in protective binnacles and suspended on gimbals to remain level despite a rolling deck—overland envoys, diplomats, and spies carried compact, palm-sized versions. Cast in brass and protected by a hard leather case for travel in a writing box or suspended from the neck, these portable instruments featured a magnetized needle balanced on a pivot above a hand-drawn wind-rose card. They provided an indispensable anchor of direction when traversing uncharted mountain passes, featureless deserts, or overcast skies where the stars were obscured.
  • The Nautical Quadrant (Quadrante Náutico):
    A simple wooden or brass quarter-circle (90 degrees) with a weighted plumb line hanging from its apex. When a mariner sighted the North Star or the sun through pinholes along the upper edge, the hanging string indicated the heavenly body’s altitude on the graduated arc below, allowing for a quick calculation of latitude.
  • The Cross-Staff (Balestilha):
    Consisting of a graduated main wooden rod and a movable perpendicular cross-piece, the cross-staff was held to the eye so the user could slide the cross-arm until its ends touched the horizon and a star. Though tricky to master without burning one’s eyes on the sun, it became a standard tool for measuring celestial angles at sea.
