Lusitanic definitions of "Lusitanic" or "Lusitanian" may include medieval-to-modern Galicia, because the Portuguese people and Galician people share close linguistic and cultural ties, including pre-Roman Celtic ones. Modern Portuguese and the Galician language both derive from medieval Galician-Portuguese, and the term is a cultural classification more than a historic–geographical definition. Although, in Ancient Roman times, the Gallaeci were not part of Lusitania province, what became the Galician-Portuguese language developed from Vulgar Latin in Gallaecia, which comprised what is now Galicia, as well as north Portugal, the center of the development of post-Roman Portuguese culture. Later Portuguese use of the name "Lusitania"
RMS Lusitania contract with the British Admiralty and other British authorities to partially salvage "Lusitania". The means of salvage was unique in that a steel tube, five feet in diameter, which enclosed stairs, and a dive chamber at the bottom would be floated out over the "Lusitania" wreck and then sunk upright, with the dive chamber resting on the main deck of "Lusitania". Divers would then take the stairs down to the dive chamber and then go out of the chamber to the deck of "Lusitania". Lake's primary business goals were to salvage the purser's safe and any items of historical value.
