Robert Vickery is for simplicity. The egg yolk already contains oil, so it is an emulsion in itself. He just adds a certain amount of distilled water to the yolk, around 3 parts of egg yolk and 1 part of water with no preservatives as it may cause trouble. He then filter his emulsion through a cheese cloth. Refer to his excellent book "New Techniques in Egg Tempera".
