In what is now Portugal south of river Douro and a portion of Spain, there was Lusitania, previously owned by Celtic-derived groups and conquered by the Romans when they invaded the Iberian Peninsula. What most people, even most of the modern Portuguese and Spanish, seem to be unaware of, is that there was a [[http://en.wikipedia.org/wiki/Lusitanian_mythology native pantheon of gods]]. Considering this is perhaps one of the least studied mythologies, there is no surprise that these gods were so little known, and today little is left after centuries of Christian domination (and a period of Islamic domination, and shorter period of the two fighting) of the Iberian Peninsula. What is known, however, is that the [[ClassicalMythology Roman religion]] adopted some of the deities (as was the norm), and that there's enough known to [[TvtropesWillEnhanceYourLife leave something written on TVTropes]].

Like in many mythologies, there are historical texts focusing on it, the most relevant being Macrobius's ''Saturnalia''.

!!Tropes:
* CastSpeciation: Of the known gods several were essentially water gods, several dedicated to war and two related to light.
* DarkIsNotEvil: Ataegina.
* EnsembleDarkhorse: Possibly Endovelicus, the only god even recognised by modern Portuguese and Spanish thanks to the amount of shrines and temples he had, and even so not a very famous figure.
* FatherNeptune: Duberdicus.
* FertileFeet: Sucellus and Nantosuelta.
* GodCouple: Duberdicus/Nabia, Sucellus/Nantosuelta (the second pair also occurring in the main CelticMythology) and possibly Bandua/Bandus, if they aren't two different names for the same god(dess).
* IntercontinuityCrossover: Having derived from the CelticMythology and being incorporated into the ClassicalMythology by the Romans, this mythology seems to have effectively mixed both continuities; for instance several gods are present in the original Celtic myths, such as Sucellus and Nantosuelta, while the Romans accepted the native gods into their canon and the mythology itself shaped to fit the Roman influences (Lusus, the ancestor of the Lusitanians and thus of modern Portuguese people, was a canon Greek/Roman character).
* LightEmUp: There are two gods related to light: Endovelicus, also associated with [[HealingHands health]], was [[LightIsGood benevolent]], while the other, Neto, was [[LightIsNotGood a war god]]. The first [[SadlyMythtaken became associated]] with Lucifer once Christianity got installed on Lusitania, while the later was incorporated into the Roman god Mars, leading to the title of Mars Neto in the Iberian Peninsula and his association with the sun (he was already an agricultural god to begin with).
* MakingASplash: Several gods were water based as mentioned above.
* OurGiantsAreBigger: Possibly Dervetius, a mountain god.
* SpellMyNameWithAnS: As in many [[CanisLatinicus Latinized names]], there are several variations to the names; Endovelicus was Aendovelicus and, in Portuguese, Endovélico. There is a possible subversion in Bandua's case as the name Bandus might have referred to the god he/she was consort to.
* ThePowerOfTheSun: Neto was one of the few solar deities in any mythology to show the Sun's real potential.
