Monumental plaque, in lioz limestone, probably for placement in façade of important family tomb, although a rim on its back initially suggested its use as a sarcophagus lid. The epigraph had a frame that was picked, quite possibly following its reuse as an altar stone in the chapel of São Julião. It also lost the inscription's first line - recorded in the 17^th century-, probably when it was displaced to Quinta de A-da-Rainha, between 1633 and 1861, having been donated to the Leonel Trindade Municipal Museum, in the early 20^th century, by the estate's owner at the time.
The writing is

square capital type, with classic pagination: in the first line, the dedication to the

Manes Gods; in the three following lines, the identification of the dedicant's husband and son; in the last two lines, there is reference to family ties and the circumstances of the monument's construction.
The names are Latin and the monument's quality and size agree with a family belonging to the

ordo decurionum, of Italic origin, despite the relation with native elements indicated by the

cognomen Avitus. Although the municipality where Q. Caecilius Caecilianus held his post is unmentioned, his presence in the

ager olisiponensis suggests he was a municipal magistrate in

Felicitas Iulia Olisipo.
Like other Roman gravestones used in the chapel of São Julião, this one must also be from the burial area of a

villa identified nearby.
