In Lao (and
Buddhist/Hindu) theology and iconography there are numerous half-human
half-animal beings and creatures with multiple parts from other
animals.
To answer your
question the answer is yes, there are in fact angels and mermaids
in Lao iconography. They are referred to as nang fa and nang
supanamuchsee, repectively.
There are many
variations of hooks in Lao textile designs. However, generally they
appear as repeating patterns and colors that give a real geometric
elegance to a design.
Hook (Lao: kaw,
Indian: ankusha). No one is entirely sure where the hook
designs came from or what is the significance they hold. Nevertheless,
there are theories. Bunce writes that one theory is that the hook
symbolizes a goad. A goad is associated with the training and taming
of the elephant. In this case it could relate to the control of
animal instincts. Bunce goes on to say, another possible theory
is that since the goad is also a part of the dress and decoration
of local rulers this could equate the goad to the sceptre as in
European royal regalia. In which case it would represent temporal
authority and dominance.
Additionally,
in Buddhist tradition, an ankusha can be seen being carried by a
deity. In these cases it appears strictly as a hook and appears
to be an offensive weapon. In this context, it can be a destroyer
of enemies and of protection.
Yet another
theory, is that since fish (and other seafood) are widely eaten
in Laos and are a large source of protein, it could refer to fish hooks and bountiful catches.
