Aclima (alsoKalmana,Lusia,Cainan,Luluwa,Âwân^[a]) according to some religious traditions was the oldest daughter ofAdam and Eve and the sister (in many sources, the twin sister) ofCain. This would make her the first woman to be born naturally.

Genesis 4:17 states that after he had killed Abel, "Cain knew his wife, and she conceived and boreEnoch". In an effort to explain where Cain and Abel acquired wives, some traditional sources stated that each child ofAdam and Eve was born with a twin who became their mate.

In Muslim tradition, Cain was born with a twin sister named Aclima, and Abel with a twin sister named Azura. Adam wished Cain to marry Abel's twin sister and Abel to marry Cain's. Cain did not consent to this arrangement, and Adam proposed to refer the question to God by means of a sacrifice. God rejected Cain's sacrifice to signify his disapproval of his marriage to Aclima, his twin sister, and Cain slew his brother in a fit of jealousy.^[1][2][3]

In another Muslim tradition, Cain's twin sister was named Lusia, while Aclima was Abel's twin sister.^[4]

In different sources, this name appears asAclimah,Aclimia,Aclimiah,Klimia.^[5] In theCave of Treasures she is called Qelima.

Some sources in the Eastern Orthodox traditions give Cain's twin sister the nameCalmana,Calmanna,Azrun, orAzura.^[5]

In the Jewish workSeder Hadorot, Cain's twin sister is calledKalmana, and Abel's twin sister called Balbira.^[6][7]

Cain's sister is namedKalmana in theApocalypse of Pseudo-Methodius (first Greek redaction) II.1.,^[8] andCalmana in theGolden Legend. The poetPetrus Riga (1140–1209) includedCalmana in his famous poemAurora, and this could have been a source for her appearance inPeter Comestor'sHistoria Scholastica. Comestor's Biblical narrative text then served as the standard textbook for Biblical education for centuries.

In an Armenian work republished in 1966, Cain's twin sister was named Cainan. This short work does not mention Cain's marriage.^[9]

In the 6th-century apocryphal workConflict of Adam and Eve with Satan, Cain's wife and twin is named Luluwa.^[10]

According to theBook of Jubilees, Âwân (also Awan, Avan or Aven, fromHebrew אָוֶןaven "vice", "iniquity", "potency") was the wife and sister ofCain and the daughter ofAdam and Eve.^[11]
