Remarks on two dimensional array tables in Latin astronomy: a case study in layout transmission

Several aspects of astronomical tables can be transmitted from one
source to another: numerical parameters, underlying functions and theoretical models, computational methods, etc. The concern here will be on the transmission of layout. We will study how a certain family of layouts was used in European Latin astronomies after its transmission from Arabic sources. Three different stages of the circulation of this layout will be identified: first transmission, assimilation and innovation. Moreover we will see how two distinct uses of the layout will finally converge in the compilation of large trigonometric tables in the 15th and 16th centuries.
