Context paragraphs:
Tombos (Nubia): Tombos is an archaeological site in northern Sudan.  The village is located at the third cataract of the Nile, not far from Kerma near the present Karmah.  An important granite quarry was located here in the Pharaonic era.  Its stone was used mostly to build statues and buildings between the river delta and the southern regions of the kingdom.  A statue to the 25th Dynasty Pharaoh Taharqa, abandoned for over 2700 years, contains inscriptions.  Around 3000 years ago, there were pyramids dedicated to ten noble Egyptians.

Mithras in comparison with other belief systems: The Roman cult of Mithras had connections with other pagan deities, syncretism being a prominent feature of Roman paganism.  Almost all Mithraea contain statues dedicated to gods of other cults, and it is common to find inscriptions dedicated to Mithras in other sanctuaries, especially those of Jupiter Dolichenus.  Mithraism was not an alternative to other pagan religions, but rather a particular way of practising pagan worship; and many Mithraic initiates can also be found worshipping in the civic religion, and as initiates of other mystery cults.

Lusitania: Lusitania ( , Portuguese: "Lusitânia" , Spanish: "Lusitania" ) or Hispania Lusitana was an ancient Iberian Roman province including approximately all of modern Portugal south of the Douro river and part of modern Spain (the present autonomous community of Extremadura and a small part of the province of Salamanca).  It was named after the Lusitani or Lusitanian people (an Indo-European people).

Dercetius: Dercetius was a mountain god in Lusitanian mythology, in the cultural area of Gallaecia and Lusitania (in the territory of modern Galicia and Extremadura (Spain) and Portugal).  Inscritptions dedicated to him have been found near Braga ("Bracara Augusta", the Roman capital of Gallaecia).

Cissonius: Cissonius (also "Cisonius", "Cesonius") was an ancient Gaulish/Celtic god.  After Visucius, Cissonius was the most common name of the Gaulish/Celtic Mercury; around seventeen inscriptions dedicated to him extend from France and Southern Germany into Switzerland.

Damona: In Gallo-Roman religion, Damona was a goddess worshipped in Gaul as the consort of Apollo Borvo and of Apollo Moritasgus.  Mary Jones interprets Damona's name as "Divine Cow" based on its resemblance to "damos" or "cow".  She has sometimes been linked with the Irish goddess Boand on the basis of this bovine association.  Van Andringa describes Damona and Bormana as the patron deities of the hot springs at Bourbonne-les-Bains and Saint-Vulbas, respectively.  Some seventeen inscriptions dedicated to Damona have been recovered, including nine from Bourbonne-les-Bains and four from Bourbon-Lancy, both spa towns in eastern France.  In one inscription from Saintes, she has the epithet "Matubergini".

Junagadh rock inscription of Rudradaman: The Junagadh rock inscription of Rudradaman, also known as the Girnar Rock inscription of Rudradaman was inscribed by the Western Satraps ruler Rudradaman I.  It is located in Girnar near Junagadh, Gujarat, India, and dated to circa 130–150 CE.  The Junagadh rock contains inscriptions of Ashoka (fourteen of the Edicts of Ashoka), Rudradaman I and Skandagupta.

List of Marshals of Portugal: This List of Marshals of Portugal contains the names of people who received the title of Marshal-General (" Marechal-general"), Army Marshal ("Marechal do Exército"), or Air Marshal ("Marechal da Força Aérea") in the history of the Portuguese Armed Forces.

Al-Kutbay: Al-Kutbay (Arabic: الكتبي‎ ‎ ) was a Nabataean god of knowledge, commerce, writing, and prophecy.  The name means, roughly, "the scribe"; it comes from the Arabic root "ktb" which means 'to write.'  A carving at the foot of Jebal Rumm in Jordan, discovered in 1959 by J. Strugell, is dedicated to al-Kutbay.  Another inscription in Wadi Es Siyyagh, on the way to the main spring of Petra contains the phrase "in front of Kutbay, this very god."  Other sites around Arabia contain inscriptions dedicated to him.

Icovellauna: Icovellauna was a Celtic goddess worshipped in Gaul.  Her places of worship included an octagonal temple at Le Sablon in Metz, originally built over a spring, from which five inscriptions dedicated to her have been recovered; and Trier, where Icovellauna was honoured in an inscription in the Altbachtal temple complex.  Both of these places lie in the valley of the Moselle river of eastern Gaul, in what are now Lorraine in France and Rhineland-Palatinate in Germany.  One such inscription was, somewhat unusually, inscribed on a copper tablet in Roman cursive letters.
