Abstract
In 1960, two chamber tombs were discovered during construction in the Tinoni area of Vescovado di Murlo. Many examples of black gloss pottery were recovered from the tombs, 43 of which were scratched with alphabetic and non-alphabetic sigla. One siglum stands out for the frequency with which it occurs (12 times) and for its unique shape; it resembles the form of a baseball. In this paper, we investigate the 'baseball' siglum, discussing its placement on the interior of the pottery and describing its variation in form. Given the frequency and the unique form of the siglum, we suspect that it had a special function for family members buried in the Tinoni tombs. We conclude the paper by speculating about this possibility.
