Vilnius, after 1785
Wood, joiner’s and carver’s work, gilding; glass, silk, velvet, metal (silver?)

The wooden aedicula-shaped glass reliquary contains a skull placed on a pillow. In the background, three smaller reliquaries of saints with inscriptions are attached to the red fabric. Under the pillow, two documents were found testifying that the relic of the head of St Felicissimus, had been extracted from the catacombs in Rome, and in 1676 was gifted to the Provincial of Poland Minor and Lithuania, Gabriel Rotermund. On 17 December 1676, its authenticity was confirmed by the administrator of the Vilnius Diocese, Mikołaj Stefan Pac, who allowed public veneration of the relic. On the same day, the provincial handed over the relic to the Church of St Michael the Archangel in Vilnius. The second document issued in 1777 to the Bernardine monk, Jan Nepomucen Pacewicz, testifies to the authenticity of the relics of the holy martyrs Urban, Jucundus, Pius, and Casta, extracted from the Priscilla catacombs in Rome. In the postscript, it is asserted that their authenticity was confirmed by the Bishop of Vilnius, Ignacy Jakub Massalski, on 15 May 1786. Most probably at that time, all five relics were placed together in the wooden reliquary. The relic of the head of St Felicissimus, gifted by Gabriel Rotermund, is mentioned in the documents of the Bernardine nuns among the treasures that pertained to the painting of the Blessed Virgin Mary as early as 1678. At that time, it was placed in a specially manufactured reliquary decorated with silver.
