Retrogradation is the landward change in position of the front of a river delta with time.

The euglyphids are a prominent group of filose amoebae that produce shells or tests that in most described species is reinforced by siliceous scales, plates, and sometimes spines, but this reinforcement is absent in other species. These elements are created within the cell and then assembled on its surface in a more or less regular arrangement, giving the test a textured appearance. There is a single opening for the long slender pseudopods, which capture food and pull the cell across the substrate.

The Battle of Apamea was fought on 19 July 998 between the forces of the Byzantine Empire and the Fatimid Caliphate. The battle was part of a series of military confrontations between the two powers over control of northern Syria and the Hamdanid emirate of Aleppo, which in turn were part of the larger series of regional conflicts known as the Arab–Byzantine wars. The Byzantine regional commander, Damian Dalassenos, had been besieging Apamea, until the arrival of the Fatimid relief army from Damascus, under Jaysh ibn Samsama. In the subsequent battle, the Byzantines were initially victorious, but a lone Kurdish rider managed to kill Dalassenos, throwing the Byzantine army into panic. The fleeing Byzantines were then pursued, with much loss of life, by the Fatimid troops. This defeat forced the Byzantine emperor Basil II to personally campaign in the region the next year, and was followed in 1001 by the conclusion of a ten-year truce between the two states.

For some time after the period of the Parthian Empire, art in its styles continued for some time. A typical feature of Parthian art is the frontality of the people shown.
