These are allusions present in the Warcraft III custom map Defense of the Ancients: Allstars variant.
Items
Aegis of the ImmortalA shield used by Zeus, the Greek god.
Aghanim's ScepterRefers to Aghanim, the final boss in some of the Zelda games.
Burize-Do KyanonAn item from Diablo II.
DagonA Semitic God.
Eul's Scepter of DivinityA tribute to the creator of the original Defense of the Ancients, which included an item of the same name. The item "Guinsoo's Scythe of Vyse" derives from it. The fact that the latter is more powerful (using ESoD as a recipe ingredient, and is in a higher tier of items) may have been to imply Guinsoo's superiority, or simply to represent the development of the map over time.
Eye of SkadiSkadi is the wife of the Van god Njord in Norse mythology. She was the Goddess of winter, and as a tribute to her the item causes a hero's attack to deal frost damage, slowing opponents.
