At the close of the 19th Century, Portuguese archaeologists discovered and examined a Roman dedication near Évora. The inscription was in Latin and read SANCTRVNESOCESIOSACRVGLIC ... QVINTCINV ... BALS. In a paper submitted to the French Société des Antiquaires, it was interpreted as Sancto Runeso Cesio Sacrum G. Licinius Quinctinus Balsensis: a dedication by Gaius Licinius Quinctinus of Balsa to a previously unknown god, Runesus Cesius. The name was interpreted as Celtic, with "Cesius" an allograph for gaesius and hence deriving from the roots *runa- and *gaiso- meaning "the Mysterious One of the Javelin (or Spear)"[1]
An alternative reading, as a single word Runesocesius, was proposed by J M Blazquez-Martinez, based on the recurring element -eso- found in Lusitanian names.[2]
