The most complete work addressing the dates of the reigns of these Sidonian kings is by the French historian Josette Elayi who shifted away from the use of biblical chronology.
Elayi used all the available documentation of the time and included inscribed Tyrian seals and stamps excavated by the Lebanese archaeologist Maurice Chehab in 1972 from Jal el-Bahr, a neighborhood in the north of Tyre, [6][7][8][9][10] Phoenician inscriptions discovered by the French archaeologist Maurice Dunand in Sidon in 1965,[11] and the systematic study of Sidonian coins which were the first coins to bear minting dates in antiquity based on the years of reign of the Sidonian kings.
[18][19] Eshmunazar I, a priest of Astarte and the founder of his namesake dynasty was enthroned King of Sidon around the time of the Achaemenid conquest of the Levant.
[20][21][22] In the mid 5th century BC, Eshmunazar's dynasty was succeeded by that of Baalshillem I; this dynastic turnover coincides with the time by which Sidon began to independently mint its own coinage bearing the images of its reigning kings.
The coins dating from the reign of the Baalshillem I dynasty show the abbreviated names of the respective kings, a custom of the Sidonian royalty.
