Most portraits are between bust and half-length. The small number of glasses with Jewish iconography are covered separately below. Either portraits or inscriptions naming private individuals are very common, though other examples have no personalizing aspect and were perhaps just bought from a dealer's stock. Portraits of married couples are at first most the common, but saints were more numerous towards the end of the period; the two are also often combined. It is not always possible to distinguish the two confidently, despite "tituli" inscriptions and a convention of using contemporary dress for owners and a conventional out of date costume for sacred figures, even recent male ones such as Pope Damasus I (r. 366–384). Damasus, exceptionally for a contemporary cleric, appears on at least four glasses, or at least it is thought he is who "DAMAS" refers to. Saints Peter and Paul together are very common, usually facing each other in profile, but sometimes with other figures. Both were martyred in Rome, and especially popular there; other local martyrs such as Agnes are depicted several times, and according to Lucy Grig "the "Roman-ness" of the saints portrayed on the Roman glasses is striking", and five popes from the 3rd and 4th centuries are probably depicted. Christ is shown in a number of examples, usually as clean-shaven and youthful, as well as figures such as the Good Shepherd which may symbolize him, or in some cases Orpheus or general bucolic imagery. A small Christ may stand between the heads of a married couple, blessing them. Orants perhaps representing the soul of an owner when not identified as a saint, and as in the catacombs always shown as female, appear a number of times, and female saints and the Virgin are always shown in the orant pose. Narrative scenes from the Old Testament are more common than miracles of Christ, as in the catacomb paintings, and the same "abbreviated representations" of scenes of deliverance feature: the story of Jonah, Daniel in the lions' den, the three youths in the Fiery Furnace. The most common scenes in later Christian art, centred around the liturgical calendar, are very rare. There are really only two non-Christian narrative scenes: one labour of Hercules (two more are shown in "sidewall blobs"), and one of Achilles, but a number of "portrait" figures, as with Christian sacred figures often combined with owners. There are a small number of "agonistic" or sporting scenes, with wrestlers, boxers, one gladiator, and several racing chariot teams.
