In Roman mythology, Securitas was the goddess of security and stability, especially the security of the Roman Empire. On coinage Securitas was usually depicted leaning on a column. She first appears on a coin in 62 AD and then becomes a usual coin motif in the following centuries. On Sardinia during the Roman imperial period, a Latin inscription described the tomb of Titus Vinius as a shrine of Securitas. . References https://en.wikipedia.org/wiki/Securitas
