Before the refurbishment of municipal infrastructure as part of the rearrangement of Gosposvetska cesta, Ljubljana, phase one of preliminary archaeological research took place between August and December 2017.

Excavation has revealed part of a major late-Roman graveyard in the western part of what is today's Ajdovščina. A special feature of this part of the Emona's northern necropolis is a 4^th-century group of inhumations in sarcophagi and masonry tombs. Serving as a covering for one of the brick tombs was a secondarily used tombstone of an Apollo's Fifteenth Legion veteran.

Made of dark grey limestone, the tombstone is carved quite precisely and deeply with centrally aligned text:

L(ucius) Obulsius, L(uci) f(ilius)

Camil{l}ia, Pisaur(o)

vet(eranus) (ionis)  Apo(llinaris)

annorum LX, t(estamento) f(ieri) [i(usit)]

Lucius Obulsius, son of Lucius,

from the Camillia voting district, native of Pisaurum,

an veteran of the Apollo's Fifteenth Legion,

aged 60, (the deceased) ordered (this stone) to be erected in his will.

Who was Lucius Obulsius?

The proposed dating and location of his burial support the assumption of L. Obulsius having belonged to the first generation of settlers, thus indirectly reinforcing the validity of the deduction on the existence of a close connection between the “establishment and commencement of operation of urban functions at Emona's new location” and being granted the status or deduction of a colony, which was accompanied by veterans and civilians settling there as the constitutive element of the new roman colonia Emona.
