General description:
"The Lateran obelisk takes his name from the nearby basilica of San Giovanni in Laterano: this obelisk was ordered by Ramses, son of Sothis, king od Egypt...when they hoisted it on, it risked falling down, because of the weight of such a huge mass. Therefore, the king ordered that his son the tied on top of it, so that the need to safe the royal child might make the architect more careful. It was later raised in Tebe, in the temple of the Sun, to which is was devoted until 334 b.c.,at the time of the Emperor Costanzo, son of Costantine the Great... who took it away and sent it to Alexandria: however, fate disappointed the Emperor's wishes. Indeed, after the death of Costantine, the obelisk stayed for a long time on Alexandria, ignored by everybody. Later on Costanzo, heir of his father's glory, ordered to take it to Rome and hoist it in the middle of the Circo Massimo , where it stayed for a long time, until the Goths invaded Rome. At that point, it collapsed and layed down on the ground until Pope Sixtus, once he recognised its value, had it unearthed, and raised once again in the Piazza del Laterano (1588), where we can still admire it now."

The obelisk was ordered by the Egyptian king Ramses I (ca. 1345 b.C.– June 1290/1289 b.C.), who was son of Sothis, head of the archers, and belonged to a warlike aristochracy from Nile delta. [Source: Kenneth A. Kitchen, "Il Faraone trionfante", Laterza, Bari (1994). p.29b]
Ferdinand III (13 July 1608 – 2 April 1657) was Holy Roman Emperor from 15 February 1637 until his death, as well as King of Hungary and Croatia, King of Bohemia and Archduke of Austria. He was Kircher's (Geisa, 2 May 1602 – Rome, 28 November 1680) patronus, especially in Kircher's Egyptian studies on obelisks. Because of that, Kircher dedicated his work on Lateran obelisk to him (infact on Lateran obelisk's press there is an iscription of Ferdinando III).
Athanasius Kircher, following Oropollo's studies (V sec. a.C, author of "Hieroglyphica") about two hundred hyrogliphical letters,understoond that the Egyptian language comes from Copto and the hyrogliphicy has a symbolic value. Kircher wrote about it: "Avendo seguito i significati reconditi esposti dagli autori…come un filo di Arianna, avvalendoci dell’aiuto della scienza analitica o combinatoria, mediante gli sforzi e le indagini di molti anni, alla fine, guidati e condotti da Dio, abbiamo penetrato gli arcani ed i misteri dei geroglifici” ( Ob. Pamph. Epist. Paraen. ad Fi.).
Although Kircher's approach to deciphering texts was based on a fundamental misconception, some modern commentators have described Kircher as the pioneer of the serious study of hieroglyphs. The data which he collected were later consulted by Champollion in his successful efforts to decode the script. Kircher himself recognized the possibility of the hieroglyphs constituting an alphabet; he included in his proposed system derivations of the Greek alphabet from 21 hieroglyphs. According to Joseph MacDonnell, it was "because of Kircher's work that scientists knew what to look for when interpreting the Rosetta stone" ( MacDonnell, p 12). Another scholar of ancient Egypt, Erik Iversen, concluded: "It is therefore Kircher's incontestable merit that he was the first to have discovered the phonetic value of an Egyptian hieroglyph. From a humanistic as well as an intellectual point of view Egyptology may very well be proud of having Kircher as its founder"( Iversen, pp 97–98).
