Philadelphus

Philadelphus is a Latinized form of the Greek name Philadelphos, derived from the elements φιλέω (phileo, “to love”) and ἀδελφός (adelphos, “brother”), meaning “brotherly love.” The name is historically associated with the Ptolemaic dynasty of Egypt, notably borne by Ptolemy II Philadelphus (308–246 BC), who ruled during the Hellenistic period. He was a patron of the arts and sciences, later credited with commissioning the Septuagint, the Greek translation of the Hebrew Bible.

Cultural Significance

The name gained wider recognition in the botanical world, as the genus Philadelphus (common name “mock-orange”) was named after Ptolemy II by Swedish botanist Linnaeus, honoring his reputation for learning and patronage.
