from the Batavia was the navigation material. Four astro-
labes were found on the site, two during the 1972-76
seasons. One was found in the stern of the site, the other
was associated with a massive concretion o f silver coins.
The astrolabes are of great interest because we know that
some form of latitude measuring device must have sur-
vived the wreck, because Pelsaert was able to determine
his latitude during the voyage from the wreck site to
Batavia. a
There are five lists of steersman's requirements in the Resolutions of the Heren XVII 16 April 1655 (Resolu/ies genomen op de ordinaris en extraordinaris vergaderingen van de Heeren XVII KA187 23 September 1654 - 22 August 1660). This is the earliest list of navigation equip- mentknown for the VOC. TheResolutionslistinstruments and maps for the skippers, uppersteersmen, for the cabin which the uppersteersmen were responsible, for under- steersmen and for the third watch.
The instrument list is as follows:

This list is very similar to the published list of charts and steersman's requirements for the ship Ternale which was published in 1673 (KA 4393"). The Ternate list seems to be a printed version of the resolutions (with some variations) onto which was entered, in handwriting, the nameoftheship,theskipper,theChamberitwassailingfor and the date of depanure. These lists would be signed to confirm the receipt of the goods.
From the Heren XVII list we can see, for example, that a ship would carry three round astrolabes, two semi- circular astrolabes, two astrolabium catholicum, twelve pairs of compasses, four graelboogh or Jacob's Starf, four Hoeckboogh or Davies's Quadrant, together with a large assortment of charts and manuals.
