Athanasian (adj.)
1580s, "pertaining to Athanasius" (c. 296-373), bishop of Alexandria in the reign of Constantine. The name is Latin, from Greek Athanasios, from athanatos "immortal," from a- "not, without" (see a- (3)) + thanatos "death" (see thanatology). The anti-Arian creed attributed to him was perhaps not his work.

Adelphi 
district of London, so called because it was laid out c. 1768 and built by four brothers of a family named Adam; from Greek adelphos "brother," literally "from the same womb, co-uterine," from copulative prefix a- "together with" (see a- (3)) + delphys "womb," which is perhaps related to dolphin. The district was the site of the popular Adelphi theater c. 1882-1900, which gave its name to a style of performance.

Atlas 
1580s, in Greek mythology a member of the older family of Gods, later regarded as a Titan, son of Iapetus and Clymene; in either case supposed to uphold the pillars of heaven (or earth), which according to one version was his punishment for being the war leader of the Titans in the struggle with the Olympian gods. "Originally the name of an Arcadian mountain god; the name was transferred to the mountain chain in Western Africa" [Beekes].

The Greek name traditionally is interpreted as "The Bearer (of the Heavens)," from a-, copulative prefix (see a- (3)), + stem of tlenai "to bear," from PIE root *tele- "to lift, support, weigh." But Beekes compares Berber adrar "mountain" and finds it plausible that the Greek name is a "folk-etymological reshaping" of this. Mount Atlas, in Mauritania, was important in Greek cosmology as a support of the heavens.
